How to read Covid data now

Higher test positivity rates are a sign that many infections are not reported — even if they are tested for at home. This results in a more severe undercount of cases. The number of hospitalized patients with Covid is a more reliable measure because testing is more consistent in hospitals. Read more about the data.

About the data

In data for Washington, The Times primarily relies on reports from the state, as well as health districts or county governments that often report ahead of the state. The state updates its data on Mondays, Wednesdays and Fridays. It released new data daily until Dec. 20, 2020, and all weekdays until Jan. 21, 2022. The state reports cases and deaths based on a person’s permanent or usual residence.

The Times has identified reporting anomalies or methodology changes in the data.

The tallies on this page include probable and confirmed cases and deaths.

Confirmed cases and deaths, which are widely considered to be an undercount of the true toll, are counts of individuals whose coronavirus infections were confirmed by a molecular laboratory test. Probable cases and deaths count individuals who meet criteria for other types of testing, symptoms and exposure, as developed by national and local governments.

Governments often revise data or report a single-day large increase in cases or deaths from unspecified days without historical revisions, which can cause an irregular pattern in the daily reported figures. The Times is excluding these anomalies from seven-day averages when possible. For agencies that do not report data every day, variation in the schedule on which cases or deaths are reported, such as around holidays, can also cause an irregular pattern in averages. The Times uses an adjustment method to vary the number of days included in an average to remove these irregularities.
