Negatives = Totals - Positives. As of April 16, WV reports hospitalization + ICU + ventilator counts from 49 of 55 counties.
Before April 16, those counts were unreliable -- based on reported percentages of completed investigations, an unpublished number.
As of May 23, West Virginia is separating out PCR and antibody tests; we report the number of PCR tests. Total tests might be impacted.
As of July 4, West Virginia makes changes to its previous data for antibody testing, so its historical time series might not match ours until we backfill our data to match theirs.
