Jefferson County Public Health staff estimate that 1 in 10 COVID-19 cases in Jefferson County were reported to public health last week.
The risk of COVID-19 transmission in crowded, indoor places lowered to moderate this week. At that level, it's recommended everyone wear a well-fitting, high-quality mask in crowded, indoor settings. This data is updated Mondays, excluding holidays.
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.
