12/05/2022: The two-week case rate is 383 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 data is updated Mondays, excluding holidays. 

Jefferson County Public Health staff estimate that 1 in 4 COVID-19 cases in Jefferson County were reported to public health last week. 

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. View more case data.
