When Alaska reports no data, several days of data, or unusual data (such as decreases in values that should increase), our volunteers note it here on the date the anomaly occurred. We also note here changes in our own methodology that affect the data.
Alaska combines PCR and antigen tests in the total tests figure reported on the state's dashboard.
Negative test results reported in our API and CSVs are calculated by subtracting Total cases from Total PCR tests (specimens) in the absence of better data.
On January 20, 2021, Alaska reported 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 COVID Response Hubthat there would be no update to their data on December 25, 2020.
On November 17, 2020, Alaska announced 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 Total cases 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.
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 as well.
On November 5, 2020, Alaska’s Total PCR tests (specimens) increased from roughly 628k to 782k. We were unable to find an explanation for the increase.
As of September 18, 2020, Alaska's total test results are drawn from our
totalTestsViral field instead of calculated via positive+negative.
