On March 5, 2021, we cleared the history of West Virginia's Negative (people or cases). The number previously mixed units and is no longer needed since totalTestResults are no longer calculated via positive+negative.

On March 5, 2021, we backfilled the history of West Virginia's Total PCR Tests (specimens) from data scraped from its dashboard. This allowed us to get historical testing data we did not have from March 13, 2020 to April 28, 2020.

On March 2, 2021, the West Virginia Department of Health and Human Resources [announced](https://dhhr.wv.gov/News/2021/Pages/COVID-19-Daily-Update-3-2-2021.aspx) that a backlog of testing results from December and January had been reported to the state after the February 26, 2021 dashboard update was published. These testing results were mistakenly reported as positive instead of negative, and are being corrected in the electronic disease surveillance system. This issue is expected to be resolved on the dashboard within the next few days. We urge caution when interpreting numbers from this time period.

On November 8, 2020, West Virgin removed one death from its confirmed death count due to erroneous reporting.

October 24, 2020

Variables affected:

On 10/24, WV continued to revise their historical timeseries for Total Antibody Tests. We revised numbers through 10/15 but are unable to automate the process due to issues with PowerBI.

October 5, 2020

Variables affected:

On 10/5, WV's confirmed/probable deaths breakdown did not work, so we carried over confirmed and probable deaths. Only total deaths were updated.

WV began separating confirmed/probable deaths on 8/12. Deleting these values from 5/4-5/11.

Tags: CTP Backfill CTP Backfill Mistake Correction

Between 5/22 and 6/4 CTP did not capture confirmed cases in WV. We can't get the values from screenshots because they require hover. We are filling out the time series with the lower bound value which is the 5/21 confirmed cases number.

Fill out probable cases in WV from 6/5 to 7/27 based on the total cases and the confirmed cases.

WV: Moved Total tests from Total PCR Tests (People) to Total Tests (PCR) as the units used by WV are unclear. Additionally we were missing Total Test data from 5/2-5/12 which was filled in using screenshots of the WV dash.

August 13, 2020

Variables affected:

On 8/13, we found that WV started reporting confirmed/probable deaths separately, using a "click-and-drop-down" system. From screenshots it seems that this is new as of 8/12.
