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.
07/05/2022: The two-week case rate is 715 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. View more case data.
