Mpox Data

Mpox Cases per County

Mpox Dashboard Technical Notes

The Washington State Department of Health (DOH) is no longer listing positive cases in non-Washington residents, those cases are counted in a person’s state or country of residence.

DOH makes every effort to publish updates on Mondays (except for state holidays). 

Due to processing, there may be some lag time between when a local health jurisdiction or health care provider confirms a positive test or reports a vaccine dose and when that information is added to the data above.

Mpox (MPV) Vaccine Summary

As of September 18, 2023, 12:50 AM (PDT), there have been 34338 administrations of MPV vaccine entered into the Washington State Immunization Information System (WAIIS). Of these, 99% have been the JYNNEOS vaccine. A total of 20860 Washington state residents have received an MPV vaccine, of which 12835 are fully vaccinated (i.e., have received two JYNNEOS).

MPV Vaccines

There are two vaccines available for MPV: JYNNEOS and ACAM2000. The current MPV outbreak response has focused on distributing JYNNEOS. There have been very few administrations of ACAM2000, although this analysis monitors for them. JYNNEOS is administered in two doses, the second of which is recommended 24-35 days after the first dose. Below is a table of patient counts organized by JYNNEOS dose number.
