Tests reported
Data notes
As of February 13, 2021, Wyoming does not update their COVID-19 data on Saturdays. Beginning on March 7, 2021, they no longer update their COVID-19 data on Saturdays or Sundays.
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. 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 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 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, 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 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 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. 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.
