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 Tuesdays (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 Vaccine Summary

As of October 02, 2024, 01:18 AM (PDT), there have been 38387 administrations of mpox vaccine entered into the Washington State Immunization Information System (WAIIS). Of these, 99% have been the JYNNEOS vaccine. A total of 23092 Washington state residents have received an mpox vaccine, of which 14517 are fully vaccinated (i.e., have received two JYNNEOS).

Mpox Vaccines

There are two vaccines available for mpox: JYNNEOS and ACAM2000. The current mpox 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.
