Case Information

3/20/2023: We are adding 32 new cases. The two-week COVID-19 case rate is 221 per 100,000 people. This week's new cases are the total number of cases reported to us from Saturday, March 11 through Friday, March 17.

Jefferson County Public Health staff estimate that 1 in 12 COVID-19 cases in Jefferson County were reported to public health last week.

The risk of COVID-19 transmission in crowded, indoor places is high. At that level, it's strongly 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.

The charts below show Jefferson County's COVID-19 hospitalizations and deaths by vaccination statuses. Vaccination statuses are recorded as “up to date,” “not up to date,” or “unvaccinated.” “Up to date” means a person had all the recommended doses of COVID-19 vaccine at the time of their hospitalization or death.

Today, being up to date means everyone six months and older has completed their primary series and received one dose of the updated, bivalent, omicron-specific booster or Novavax booster.

Our staff recommend the bivalent booster for everyone. These charts strongly suggest being up to date on COVID-19 vaccinations protects against hospitalization and death.
