As a result, we will be unable to update their data on Saturdays and Sundays. On February 12, 2021, Alaska [announced](https://twitter.com/Alaska_DHSS/status/1360413364065767424?s=20) via the official Alaska Department of Health and Social Services twitter that there would be no update to their data on February 15, 2021 due to the Presidents Day holiday.On January 20, 2021, Alaska [reported](https://www.adn.com/alaska-news/2021/01/20/tracking-covid-19-in-alaska-record-23-deaths-and-167-infections-reported-wednesday/) a comparatively large increase of 23 deaths due to a review of death certificates.On January 4, 2020, Alaska noted that ""counted deaths in Alaska include COVID-19 cases confirmed through a lab result as well as probable deaths based on confirmed COVID-19 clinical and epidemiological criteria as defined by the CDC with no confirmatory lab testing."" Due to this change we are unable to update the **Confirmed deaths** metric after January 4, 2020.On January 1, 2021, Alaska noted that there would be no update to their data on January 1, 2021.On December 25, 2020, Alaska announced on their dashboard that there would be no update to their data on December 25, 2020. On November 17, 2020, Alaska [announced](https://alaska-coronavirus-vaccine-outreach-alaska-dhss.hub.arcgis.com/datasets/cases-frequently-asked-questions) that “As of 11/17/2020, the cases dashboard will not be showing data on recovered and active cases due to the increasing State case load”. Due to this we cannot continue reporting **Recovered**, however the time series for this metric is available in the historical data, and our data downloads. On November 16, 2020 we updated the **Cases (confirmed plus probable)** field to include only residents. We also deleted the time series for **Confirmed cases** because Alaska is lumping PCR and antigen testing for their case definition.On November 16, 2020 we added **Cumulative Hospitalized** (which includes both residents and non-residents), although the value does not reflect current hospitalizations.On November 7, 2020, Alaska announced that their testing dashboard would be ""temporarily disabled from November 6th to November 9th"" and that testing data could be accessed through their data summary tables. After originally using the data summary tables on November 7, we have reversed that decision, and reverted the values to their November 6th state. The frozen values were replaced on November 10, with values from the state's [Tests Dataset](https://coronavirus-response-alaska-dhss.hub.arcgis.com/datasets/tests-dataset). On November 6, 2020, Alaska’s **Total PCR tests (specimens)** and **Positive PCR tests (specimens)** decreased without explanation. As a result, `Negative`, which is calculated by subtracting **Total cases** from **Total PCR tests (specimens)**, decreased also.On November 5, 2020, Alaska’s **Total PCR tests (specimens)** increased from roughly 628k to 782k.

3,AR,"Arkansas reports a category of “non-COVID deaths,” representing individuals who died with COVID positive but of causes unrelated to COVID. We do not count these individuals in our deaths metric, consistent with our policy of tracking only individuals with COVID as a cause of death where possible.On February 28, 2021, Arkansas’s total Deaths decreased by over 200. Arkansas [stated](https://twitter.com/ADHPIO/status/1366163333225799682) that this decrease was because of data clean-up and deduplication.During the week of September 20, 2020, Arkansas made some continual adjustments to its antigen people tested numbers, resulting in some fluctuation in its negatives and totals.As of September 18, 2020, Arkansas's total test results are drawn from our `totalTestsViral` field instead of calculated via positive+negative. The totals do not include repeat positives—counting individuals only for their first positive—but do count repeat negative tests.On September 16, 2020, Arkansas’s **Negative Tests (PCR)** dropped by 26,801 tests, causing its **Total Tests (PCR)** to drop by 26,195 tests due to the reversal of a data dump of negative test results. It also added 140 **Probable deaths**, not all of which dated to September 16.On September 3, 2020, Arkansas began reporting **Probable cases** according to the most recent CSTE definitions, in addition to confirmed cases. This added 423 new cases to AR’s **Total cases** number.On Aug 15, 2020, Arkansas data changed due to deduplication and the state's removal of out-of-state cases from its dataset. These changes resulted in reductions in **Total cases**, **Ever hospitalized**, and **Ever in ICU** data. Between July 30, 2020 and September 17, 2020, Arkansas provided Total, Positive, and Negative Antigen tests (specimens) sporadically and then stopped reporting them.

5,AZ,"Arizona combines PCR and antigen tests in the total tests figure reported on the state’s dashboardArizona regularly reviews and removes duplicate records which may occasionally result in minor decreases of cumulative figures. The **Recovered** data point we report for Arizona reflects the number of COVID-19 patients discharged from the hospital and therefore does not represent the total number of people who have recovered from COVID-19, since many people with COVID are never hospitalized.Negative test results reported in our API and CSVs are calculated by subtracting **Confirmed cases** from **Total PCR tests (people)** in the absence of better data.On March 1, 2021, Arizona [announced](https://twitter.com/AZDHS/status/1366405875754291212?s=20) via the official Arizona Department of Health Twitter that due to death certificate matching, Confirmed deaths increased by 1, and Probable deaths decreased by 2. As a result, Deaths (confirmed + probable) decreased by 1.On February 22, 2021, Arizona [announced](https://twitter.com/AZDHS/status/1363869914356994054?s=20) via the Department of Health's official Twitter that no new deaths were reported. Additionally, there was a decrease of 3 deaths (confirmed and probable) due to death certificate matching.On January 18, 2021 Arizona [announced](https://twitter.com/AZDHS/status/1351183189100867586) via the official Arizona Department of Health twitter that their reported Deaths (confirmed and probable) decreased by one due to de-duplication of the data.On January 9, 2021, Arizona [announced](https://twitter.com/AZDHS/status/1347930259170021376?s=20) that the number of COVID-19 patients in ICU was incomplete on their COVID-19 dashboard, and we sourced Currently in ICU from the official Arizona Department of Health twitter.On December 28, 2020, Arizona [noted](https://twitter.com/AZDHS/status/1343575976026886144) that due to the holiday weekend, multiple days of case reviews were completed, resulting in the data for December 28, 2020 being higher than usual. As a result, they reported a larger increase in Confirmed cases than Total PCR tests (people), which caused their Negative PCR tests (people), which is calculated as Total PCR tests (people) minus Confirmed cases, to decrease.As of December 10, 2020, Arizona's total test results are drawn from our `totalTestsViral` field instead of calculated via positive+negative. We backfilled the data for March 2 2020 through December 8 2020 using the time-series posted on Arizona's dashboard as [Diagnostic Tests Conducted](https://tableau.azdhs.gov/views/ELRv2testlevelandpeopletested/TestsConducted?:isGuestRedirectFromVizportal=y&:embed=y). On December 1, 2020, Arizona [announced](https://twitter.com/AZDHS/status/1333791978992017408) that figures reported on December 1, 2020, would be higher than normal due to a delay in case review and reported over the Thanksgiving weekend.On October 6, 2020, the Arizona Department of Health Services [announced](https://directorsblog.health.azdhs.gov/covid-19-hospitalizations-in-arizona/?utm_source=TWITTER&utm_medium=AZDHS&utm_campaign=covid19,Director%27s+Blog&utm_content=3840149936&linkId=101333440) that they were removing cases who had been admitted to a hospital but had not been hospitalized from their total hospitalization counts. This results in a decrease of Arizona's cumulative hospitalizations.On September 18, 2020, Arizona reported a policy change in the way they count people with positive antigen testing results to comply with CSTE case definitions. This appears to have resulted in a large increase in probable cases and also likely the reason where a decrease in confirmed cases was observed. On September 16, 2020, Arizona added antigen testing into its main totals figure. This appears to have raised its Total Tests (PCR) number more than usual.From July 18–August 5, 2020, Arizona’s dashboard stopped displaying confirmed and probable breakdowns for **Cases** and **Deaths**, so we could not update **Confirmed Cases,** **Probable Cases,** **Confirmed Deaths,** or **Probable Deaths** during this period. We were still able to update the total data points for **Cases (confirmed plus probable)** and **Deaths (confirmed plus probable)**. We will backfill the separate confirmed and probable case and death data if Arizona provides historical numbers.On June 23, 2020, we updated our historical data for **Cumulative hospitalized** to match Arizona's dashboard data for ""hospitalized by date admitted."" Data for this metric is not typically reported until several days after admittance.

6,CA,"On February 25, 2021, California announced that their deaths included a backlog of 806 deaths initially not reported as COVID-19 deaths from Los Angeles County. As a result, many of the deaths reported on February 25, 2021 occurred between December 3, 2020 and February 3, 2021. We urge caution when interpreting numbers from this period, and encourage the use of 7 and 14-day averages as more reliable metrics than individual figures.On December 16, 2020, California [announced](https://www.cdph.ca.gov/Programs/OPA/Pages/NR20-338.aspx) that their cases for December 16, 2020 include 15,337 cases from previous days due to a change in case processing. It appears this new process will regularly include a higher volume of cases that were not identified within the previous 24 hours.As of September 18, 2020, California's total test results are drawn from our `totalTestsViral` field instead of calculated via positive+negative.From July 23 through July 28, 2020, California reported that its **Now hospitalized** and **Now in ICU** were incomplete due to its transition to the HHS reporting system. We carried over hospitalization figures until July 28. We will backfill the complete numbers for this period if the complete data becomes available.From June 29 to July 5, 2020, California made revisions to daily **case** numbers. On July 17, we updated the values based on the most recent data from the state dashboard.On July 8, 2020, California data included a backlog from Los Angeles County, which had not reported for several days. Approximately 1,000 of the 11,000 new cases were attributed to this backlog data.As of April 22, 2020, California has reported specimens tested instead of people tested. Because some people may be tested more than once, this number is probably higher than the number of people tested.On April 4 and April 22, 2020, California reported large batches of backlogged **negative test** data. Prior to April 1, 2020, we used county data sources for more reliably timely reporting of California's COVID-19 data. At the start of April, we began reporting primarily from the state data dashboard(s).

Connecticut stopped reporting hospital discharges on October 22, 2020, but the time series for the metric is available in the historical data, and our data downloads. As of February 23, 2021, Connecticut's `totalTestResults` field is taken directly from `totalTestsViral` instead of calculated from positive + negative. We also cleared the history of Negative (people or cases) since it was calculated using mixed units.On February 3, 2021, we updated the **Total Antigen Tests** and backfilled **Positive Antigen Tests** and **Negative Antigen Tests** from Connecticut's testing dataset provided by the state. Going forward, we'll be updating all these 3 metrics on weekdays. On February 23, we backfilled **Total PCR Tests (specimens)** from the same source so that it would only include PCR tests. This resulted in a drop at the topline of 345,693 tests, distributed over the timeseries.On December 25, 2020, Connecticut announced on their [COVID-19 page](https://portal.ct.gov/Coronavirus/COVID-19-Data-Tracker) that there would be no update to their data on December 25, 2020 through December 27, 2020 or on January 1, 2021 due to the holidays.On November 26, 2020, Connecticut announced via a [press release](https://portal.ct.gov/Office-of-the-Governor/News/Press-Releases/2020/11-2020/Governor-Lamont-Coronavirus-Update-November-25) that there would be no update to their data on November 26, 2020 due to the Thanksgiving holiday.

12,GA,"On February 3, 2021, we moved Georgia’s history of Positive Antigen Tests (people) to Probable Cases, since the state calls the metric “antigen positive cases.” We also backfilled Positive (people, confirmed + probable) to include these values. This change resulted in the addition of 162,028 cases in Georgia distributed over the timeseries from November 3, 2020 onward. Georgia does not provide a full history of this number, so on November 3, 2020 we record 29,937 probable cases for Georgia, many of which do not date to that day.On January 6, 2021, Georgia stated on its dashboard that its data would be delayed several hours “due to a high volume of data to process.” Georgia’s data did not update before for our publication time. We were able to update their Currently hospitalized from their separate [hospitalization source](https://www.arcgis.com/apps/opsdashboard/index.html#/e40c39564f724af7bfe8fd5d88deadb6).On November 13, 2020, we backfilled the **Total PCR tests (specimens)** time series to include only PCR testing, reported by the state in their data download file. This updates the previously reported series that until May 27, 2020 included both PCR and antibody tests.On November 3, 2020, Georgia started reporting probable deaths and antigen positive cases in their COVID-19 Daily Status report. On November 4, we added the probable deaths in our **Deaths (probable)** field for November 3 and 4, causing the daily rise in deaths on the 3rd to appear as 480. This large increase includes the data dump of 450 probable deaths, many of which are not from the most recent 24 hour period. We also began recording the 29,937 antigen positive cases in our `positiveTestsPeopleAntigen` API field.

The number of unique people tested is available in our API as `totalTestsPeopleViral`.On September 2, 2020, MA [reported](https://www.mass.gov/doc/covid-19-dashboard-september-2-2020/download) that it had shifted to using the more restrictive August 6 definition of probable cases released by the CSTE. This change caused a significant decrease in several data points where probable cases or probable deaths were included, particularly the overall case count, which dropped by more than 7,000. Historical data was also affected. On August 31, 2020 we updated Massachusetts' **Total PCR Tests (specimens)** before August 12, 2020 based on the state's ""Tests by Date"" dataset, extending the column back to January 22, 2020.On August 12, 2020, Massachusetts began reporting **probable cases** weekly instead of daily. This can lead to apparent spikes in the data when the weekly numbers are incorporated, as happened on August 19. Beginning August 20, 2020, we will use the daily total case count from the race and ethnicity section of the dashboard, which includes both confirmed and probable cases, and will backfill the previous week's case counts.On July 31, 2020, Massachusetts noted that ""Delays in the reporting of test results to DPH from multiple laboratories, including large national commercial laboratories, are reflected in today’s case counts. However, these positive test results have been assigned retrospectively to the appropriate date of test."" We will backfill case data for Massachusetts in the near future.On June 30, 2020, Massachusetts decreased the number of **cumulative hospitalizations** and **confirmed and probable deaths** ""due to ongoing data cleaning which identifies and removes duplicate reports.""On June 1, 2020, Massachusetts began to report **probable cases** and **probable deaths*, causing **Total cases** and **Total deaths** to appear to increase sharply in our data.

39,OH,"Since February 10, 2021, Ohio has been reconciling their death data. As a result, death figures may fluctuate more than normal, and may include deaths which were not reported in the previous 24 hours. We urge caution when interpreting data from this period and encourage the use of 7 and 14-day averages as more reliable metrics. Our data quality team will continue to investigate how best to handle changes to their data.Ohio continually updates its **Currently hospitalized / Now hospitalized** data which can cause slight differences between their historic data and ours. On February 10, 2021, Ohio [announced](https://odh.ohio.gov/wps/portal/gov/odh/media-center/odh-news-releases/odh-news-release-02-10-20) that up to 4,000 COVID-19 deaths were underreported in the state’s reporting system and on their COVID-29 dashboard. These deaths will be added to their counts over the week on February 11, 2021. As a result, new deaths will be substantially higher than normal throughout this period. We urge caution when interpreting data from this period. Our data quality team will continue to investigate how best to handle the addition of these death. Approximately 650 of the deaths reported on February 11, 2021, 2500 of the deaths reported on February 12, 2021, and 1125 of the deaths reported on February 13, 2021 are a result of this reconciliation. On February 15, 2021, Ohio noted that they were continuing to reconcile deaths through a deep review of data which may result in fluctuations in death data.On January 6, 2021, we switched Ohio's `totalTestResults` to draw from `totalTestsViral` instead of by calculating from positive+negative. On December 29, 2020, Ohio provided a timeseries of Total Tests (PCR), Positive Tests (PCR), Total Antigen Tests, and Positive Antigen Tests. On January 6, 2021, we backfilled all 4 metrics from this download, which resulted in the addition of three new metrics (positive tests PCR, positive tests antigen, total tests antigen) and a full history for Total Tests (PCR).On December 25, 2020, Ohio announced on their [COVID-19 dashboard](https://coronavirus.ohio.gov/wps/portal/gov/covid-19/dashboards/overview/) that there would be no update to their data on December 25, 2020 due to the holiday. Additionally, they noted that the data for December 26, 2020 will include numbers from both December 25, 2020 and December 26, 2020. On January 1, 2021, they noted that there would be no update to their data on January 1, 2021 due to the holiday, and that data for January 2, 2021 will include numbers from both January 1, 2021 and January 2, 2021. On December 19, 2020, Ohio announced that the case numbers for December 19, 2020 may be slightly lower than otherwise due to a technical issue.On December 8, 2020, Ohio announced that their data for December 8, 2020 includes a backlog of roughly 13,000 antigen tests dating back to November 1, 2020. As a result not all new **Probable cases** and **Total cases** were reported in the previous 24 hour period. This followed the state reporting on it's COVID-19 Dashboard that the data was incomplete and ""because of unprecedented volume, thousands of reports are pending review"" from November 18, 2020 to December 7, 2020.  On November 26, 2020, Ohio announced on their COVID-19 dashboard that there would not be a data update on November 26, 2020 due to the Thanksgiving holiday.

Additionally, on November 23, 2020, Ohio did not update their **Total PCR tests (specimens)** by the time of our daily update. Because `Negative` is calculated by subtracting **Confirmed cases** from **Total PCR tests (specimens)**, we did not update them on November 23, 2020.On November 18, 2020, Ohio reported 5246480 **Total PCR tests (specimens)** - the same number that was reported on November 15, 2020, and a drop of roughly 102k tests from November 17, 2020.

41,OR,"As of January 13, 2021, Oregon’s data is on a 1 day lag in our timeseries due to consistently updating after 7:30 pm Eastern Time, when we publish our daily update.On February 8, 2021, we cleared the history of our confirmed and probable cases fields in Oregon. Before Oregon switched to reporting tests in units of specimens, we had used its figures for people testing positive to represent confirmed cases and subtracted that number from total cases to get probable cases. However, it turned out that Oregon's people tested figure included people testing positive with antigen, so the positive people tested figure did not accurately reflect confirmed cases.On January 29, 2021, Oregon [announced](https://twitter.com/ohaoregon/status/1355286471687745537?s=21) that their COVID-19 case database would be down “for server and file migration maintenance” on January 30, 2021, and as a result there would be no update to their data on January 31, 2021. Because Oregon’s data is on a one day lag in our timeseries due to late updates, we were unable to update their data on February 1, 2021.As of December 9, 2020, Oregon’s total test results are drawn from our `totalTestsViral` field instead of calculated via positive+negative. This change will cause Oregon’s `totalTestResults` to begin on March 29, 2020 instead of March 4, 2020. Because Oregon’s totalTestsViral represent only electronic laboratory reporting, whereas its cases and negatives represented tests from all sources, this change causes a decrease of 10,296 tests in `totalTestResults` on March 29. The old numbers remain available by summing the positive and negative fields of our API.In addition, Oregon has not reported their total tests in people units since December 2, 2020 and they indicated that they will not continue to report total tests in people, so we have removed any values in **Total PCR tests (people)** we previously carried over.On December 3, 2020, Oregon removed its total people tested metric, after adding total specimens on December 1. Because they did not provide a full timeseries of specimens, as of December 4, we switched our totalTestResults from people to specimens on December 2, 2020, and stopped calculating **Negative (people or cases)**. This causes an artificial increase of totalTestResults by 960,248 on that day. On December 1, 2020, **Negative (people or cases)** decreased by 3,258 from 968,686 to 965,428. Oregon did not post an explanation. Since `totalTestResults` are computed positive+negative in the state, this caused `totalTestResults` to drop by 2,035.On November 5, 2020 we began reporting current hospitalizations from [Oregon's COVID-19 Update Dashboard](https://public.tableau.com/profile/oregon.health.authority.covid.19#!/vizhome/OregonCOVID-19Update/HospitalCapacity). Previously we had been capturing these metrics on the [Oregon Health Authority page](https://govstatus.egov.com/OR-OHA-COVID-19).On November 4, 2020, Oregon stopped reporting current hospitalization data on the [Oregon Health Authority page](https://govstatus.egov.com/OR-OHA-COVID-19), and so we did not update Oregon's current hospitalization data. Current hospitalization data is provided on Oregon's data dashboard, but it lags a day behind the other source. We will evaluate this change and resume reporting Oregon hospital data when we are sure we can preserve the time series. On October 9, 2020, Oregon [announced}(https://www.oregon.gov/oha/ERD/Pages/OHA-changes-recovered-cases-reporting.aspx) they were removing the **Recovered** metric from their reporting and working on a revised definition of recovered.

On December 11, 2020, Texas added probable cases to their dashboard, and provided a timeseries of **Probable cases** going back to November 1, 2020. On December 12, 2020, we backfilled the **Probable cases** and adjusted  **Cases (confirmed plus probable)** based on the data provided by Texas. This causes the daily rise in Texas probable cases on November 1, 2020, to appear as 71,734. This large increase includes the data dump of 67,475 **Probable cases**, most of which are not from the most recent 24 hour period. We also backfilled **Positive antibody tests (specimens)** from the data provided by Texas at the same time.On November 11, 2020, Texas reported that their update to **Deaths (confirmed and probable)** would be delayed due to technical difficulties.As of August 16, 2020, several commercial laboratories submitted previously backlogged test results to the Texas Department of State Health Services. As a result, new confirmed cases may not have occurred in the past 24 hours. The Texas Department of State Health Services is working to resolve these issues.On August 2, 2020, Texas noted that ""New data will not be posted on this dashboard on Sunday, August 2 due to a scheduled upgrade to the system that processes electronic lab reports. Data for Sunday will be posted with Monday’s data update.""On July 30, 2020, Texas noted that ""Cumulative fatalities have been corrected for July 27–29. As DSHS shifted to using death certificate data to count fatalities this week, an automation error caused approximately 225 fatalities to be included that did not have COVID-19 listed as a direct cause of death.""On July 27, 2020, Texas added 675 additional deaths through death certificate reviews. However only 44 deaths were truly ""new"" deaths on July 27. This will create a one-day artificial apparent daily increase in deaths.On July 25, 2020, Texas reported that 2092 probable cases had been removed from the statewide case totals by the Corpus Christi-Nueces County Public Health District. That removal meant that the number of total cases for Texas appeared smaller than it was. The actual number of new cases in Texas that day was 8,112, not 6,020. Starting July 23, 2020, Texas has reported that its current hospitalization and ICU numbers are incomplete due to its transition to the HHS reporting system.

49,UT,"On February 12, 2021, we cleared the history of Utah's **Confirmed cases** field, which we previously filled using data from its positive people tested via PCR number. Utah does not present this figure as confirmed cases and instead calls its main case number, which includes both PCR and antigen tests, ""lab-confirmed cases."" We did not duplicate Utah's main case number into Confirmed cases to replace this positive PCR individuals number because the definition the state uses for ""confirmed"" is not in accordance with CSTE definitions.On December 25, 2020, Utah did not update their data by the time of our daily update, presumably due to the Christmas holiday.On November 25, 2020, Utah [announced](https://twitter.com/UtahCoronavirus/status/1331703634942451715) via their official Utah COVID-19 response twitter that there would be no update to their data on November 26, 2020. Additionally, the data that would normally have been published on November 26, 2020 will be included in the November 27, 2020 update.As of November 9, 2020, our **Confirmed cases** metric for Utah is sourced from the data download available on the [Utah dashboard](https://coronavirus-dashboard.utah.gov/), which separates PCR and antigen tests. This caused a slight decrease in the number of **Confirmed Cases**.As of November 6, 2020, our **Total PCR tests (people)** and **Negative PCR tests (people)** metrics for Utah are sourced from the data download available on the [Utah dashboard](https://coronavirus-dashboard.utah.gov/), which separates PCR and antigen tests.As of October 28, 2020, our **Total PCR tests (specimens)** and **Positive PCR tests (specimens)** metrics for Utah are sourced from the data download available on the [Utah dashboard](https://coronavirus-dashboard.utah.gov/), which separates PCR and antigen tests. **Total PCR tests (specimens)** is calculated by adding positive and negative PCR tests from this [download](https://coronavirus-dashboard.utah.gov/Utah_COVID19_data.zip).As of October 29, 2020, Utah's `totalTestResults` field represents encounters instead of pos+neg. The number of unique people ever tested remains available in the `totalTestsPeopleViral` field. As of July 16, 2020, Utah is reporting both specimens and people tested. We report positives and negatives based on the number of people tested.As of June 11, 2020, Utah reports a combined case count for total intubated patients and patients on a ventilator.

52,VT,"Negative test results reported in our API and CSVs are calculated by subtracting **Confirmed cases** from **Total PCR tests (people)**. On February 13, 2021 Vermont's reported **Total Tests (PCR)** declined from 961,542 to 958,666 without explanation.On February 02, 2021, Vermont reported a decrease in Total PCR Tests (specimens) of around 23K without explanation.On January 4, 2020, Vermont posted that ""the numbers of COVID-19 deaths now includes deaths among probable cases since September 6, 2020."" Due to this change we are unable to update the **Confirmed deaths** metric after January 4, 2020.On December 23, 2020, Vermont announced on their [COVID-19 page](https://www.healthvermont.gov/response/infectious-disease/2019-novel-coronavirus)that there would be no update to their data on December 24, 2020 or December 25, 2020. On January 1, 2020, they noted that there would be no update to their data on January 1, 2020. On December 23, 2020, Vermont reported more new **Confirmed cases** than new **Total PCR Tests (people)**, which caused a decrease in the value of **Negative PCR tests (people)** in our API.On December 4, 2020, Vermont provided a timeseries for both confirmed and probable cases. We backfilled **Total cases**, **Confirmed cases** and **Probable cases** and updated **Total Tests (in People)** and **Negative** to match the new confirmed series.On December 2, 2020, Vermont added approximately 120 cases to its case count, representing **Probable cases** since the beginning of September in the state (previously, the state had only reported PCR-confirmed cases). It provided a timeseries, and we backfilled our **Total cases** field to avoid the impression of an additional 120 case rise on December 2.On November 26, 2020, Vermont announced on their [COVID-19 page](https://www.healthvermont.gov/covid-19) that there would be no update to their data on November 26, 2020.On November 3, 2020, Vermont’s **Total PCR tests (people)** decreased without explanation. As a result, Vermont’s negative test results, which are calculated by subtracting **Confirmed cases** from **Total PCR tests (people)** decreased as well.On October 29, 2020, Vermont started publishing **Total PCR Tests (in specimens)** in addition to **Total PCR Tests (in people)**. We backfilled the full time series for this metric from Vermont's Arcgis layer.As of October 29, 2020, Vermont's total test results are drawn from our `totalTestViral` field instead of calculated via positive+negative. On September 23, 2020, Vermont's **total tests** decreased by about 80 tests with no explanation. On August 19, 2020, Vermont's **total tests** decreased by about 200 tests with no explanation.

56,WY,"As of February 13, 2021, Wyoming does not update their COVID-19 data on Saturdays.Wyoming’s metrics do not update every day, and don’t always update together. As a result, please exercise extra caution when using numbers that are calculated from daily changes, especially if these calculations use multiple metrics. If anomalies are observed, numbers from previous days will be carried over until corrections are made.Wyoming reports the number of people *Ever hospitalized* with COVID-19 as a percentage of “Lab Confirmed Cases by Reported Hospitalization” on their [Statistics page](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-map-and-statistics/). In the absence of a better data source we convert this percentage to an integer, and as a result of the calculation, this value may fluctuate.Negatives reported in our API and CSVs are calculated by subtracting **Confirmed cases** from **Total PCR tests (people)**.On February 9, 2021, Wyoming’s Total PCR tests (specimens) fell from 704,836 to 595,970. We carried the previous day’s number as we believed this may have been an error. On February 10, 2021, we learned that the decrease was ""Due to recent changes in reporting by commercial laboratories, some test results were being counted twice. Testing numbers have been corrected to reflect these changes therefore a decrease in the testing numbers will be observed for Non-WPHL labs. That decrease is attributed to the removal of duplicate tests being reported"". As a result of this new information, we are backfilling our Total PCR tests (specimens) to reflect this new information and ensure that our data aligns as closely as possible with Wyoming's.On February 7, 2021, Wyoming’s **Confirmed cases** decreased by 36 and **Recovered** decreased by 2 with no explanation.On February 02, 2021, Wyoming’s Total PCR tests (specimens) decreased by roughly 4,600 and their Total PCR tests (people) decreased by approximately 1,500 without explanation. As a result, Negative PCR tests (people), which is calculated as Total PCR tests (people) minus Confirmed cases, decreased by roughly 1,600.On January 25, 2021, Wyoming’s **Total PCR tests (specimens)** decreased by roughly 106k, and their **Total PCR tests (people)** decreased by about 3.6k without explanation. Their **Positive PCR tests (specimens)** and **Negative PCR tests (specimens)** did not reflect that decrease, so we did not update their **Total PCR tests (specimens)**, **Total PCR tests (people)**, or **Negative PCR tests (people)**, which is calculated as **Total PCR tests (people)** minus **Confirmed cases** on January 25, 2021 to ensure our data is as accurate as possible.On January 12, 2021, Wyoming reported more new Confirmed cases than new Total PCR tests (people). As a result, Negative PCR tests (people), which is calculated as Total PCR tests (people) minus Confirmed Cases decreased by 85.On December 24, 2020, Wyoming announced on their [COVID-19 page](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/) that there would be no update to their data on December 24, 2020 or December 25, 2020. On January 1, 2021, they noted that there would be no update to their data on January 1, 2021.We were able to update **Now hospitalized** from Wyoming's separate [hospitalization source](https://sites.google.com/wyo.gov/exec-covid19/hospital-resources) on both days.On December 2, 2020, Wyoming's cumulative **Positive PCR Tests (specimens)** decreased by about 2,000, **Negative PCR Tests (specimens)** decreased by about 13,000, and **Total PCR Tests (specimens)** decreased by about 11,000. The data for these metrics, obtained by downloading the Crosstab data on [Wyoming's State and County Dashboards](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-state-and-county-dashboards/), has been unreliable over the last week. Please use caution when using this data.  As of November 25, 2020, Wyoming's total test results are drawn from our `totalTestViral` field instead of calculated via positive+negative. On November 27, 2020, Wyoming’s **Positive PCR tests (specimens)** decreased by about 10,000 without explanation. We believed that this decrease may be an error, and did not update Wyoming’s **Positive PCR tests (specimens)** and **Negative PCR tests (specimens)**, which come from the same source on November 27, 2020. On November 28, 2020, and November 29, 2020, we were unable to update Positive PCR tests (specimens) and Negative PCR tests (specimens) because Wyoming only updates these metrics on Monday through Friday.On November 26, 2020, Wyoming announced on their [COVID-19 page](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/) that there would be no update to their data on November 26, 2020.On November 25, 2020, we started collecting *Total PCR tests (specimens)* from the ""Wyoming Updates"" section of Wyoming's [COVID-19 page](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/) and started collecting **Positive tests PCR (specimens)** and **Negative tests PCR (specimens)** from the values in the graph on the ""Laboratory Results by Date"" graph on their [COVID-19 State and County Dashboards page](https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-state-and-county-dashboards/). At the same time, we backfilled all three of the above time series based on the numbers from the second page, summing the positive and negative numbers to use for the historical totals.On November 17, 2020, Wyoming’s **Confirmed cases** increased by more than their **Total PCR tests (specimens)** without explanation. As a result, **Negative PCR tests (people)**, which are calculated by subtracting **Confirmed cases** from **Total PCR tests (specimens)** decreased.On October 14, 2020, Wyoming's **Total PCR Tests (specimens)** and **Total PCR Tests (people)** values both decreased by over 1000 with no explanation. We believe the state might have deduplicated its data.On June 19, 2020, Wyoming began reporting **Total PCR tests (people)** as well as **Total PCR tests (specimens)**.On April 28, 2020, we began to report **probable cases** together with **confirmed cases**.During the week of April 7, 2020, Wyoming began to report both confirmed and probable cases in its **Recovered** metrics.During the week of April 6, 2020, Wyoming began reporting confirmed and probable cases separately.",https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/,https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-map-and-statistics/,https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/covid-19-testing-data/,https://sites.google.com/wyo.gov/exec-covid19/hospital-resources,https://public.tableau.com/views/StateandCountyDashboard/Dashboard1?:embed=y&:showVizHome=no&:host_url=https%3A%2F%2Fpublic.tableau.com%2F&:embed_code_version=3&:tabs=no&:toolbar=yes&:animate_transition=yes&:display_static_image=no&:display_spinner=no&:display_overlay=yes&:display_count=yes&:language=en&publish=yes&:loadOrderID=0,@health_wyoming,https://health.wyo.gov/publichealth/infectious-disease-epidemiology-unit/disease/novel-coronavirus/,Specimens,totalTestsViral,Total Tests (PCR),No data,false,Wyoming,56
