Case Information

Gauge for Case Information Page

Masking in public, indoor places is recommended, although no longer required, depending on the level of the Jefferson County COVID-19 case rate, shown above. 

05/20/2022: The two-week case rate is 848 cases per 100,000 people. The risk of COVID-19 transmission in public, indoor places is high. At this level, it's strongly recommended everyone wear a well-fitting, high-quality mask in public, indoor settings. This gauge is updated Tuesdays and Fridays. 

A basic measure of disease frequency is rate. The counties in Washington State all use the same formula in order to make it easy to compare rates with one another. To calculate a two-week case rate, we divide the number of cases that occur in a two-week period by the number of people in the county. We then multiply that result by 100,000, showing what the figure would be if all counties had the same population of 100,000. 

05/20/2022: We are adding 14 cases today, bringing the total to 3,875.

We now include some statewide case rate information published by the Washington State Department of Health, seen in a separate table below Cases by Age. Click here to view the state's report

% Positive in Past 4 Weeks

We calculate our weekly positivity rate by dividing the number of positive test results by the total number of tests taken. Note that, for this particular stat, we only use test results reported to us from Jefferson Healthcare and do not include home test results or results from other labs. That’s because we don’t know the total number of home tests being done so including those positive tests would make the percent positive higher than it should be. We DO incorporate home test results and results reported from other labs when calculating our total case count and our two-week case rate.
