What is Mpox?
Mpox is a rare disease caused by infection with the monkeypox virus. Monkeypox virus is part of the same family of viruses as variola virus, the virus that causes smallpox. It is spread through close physical contact between people.
Symptoms of monkeypox include a rash that can look like pimples or blisters that appears on the face, inside the mouth, and on other parts of the body, like the hands, feet, chest, genitals, or anus. It is often associated with a flu like illness including fever, headache, muscle aches, backache, swollen lymph nodes, chills, and exhaustion which can appear 1-3 days before the rash. The rash goes through different stages before healing completely. The illness typically lasts 2-4 weeks. Sometimes, people get a rash first, followed by other symptoms. Others only experience a rash. Immunocompromised people, children and pregnant people are at increased risk for severe disease.
Contact your healthcare provider immediately to be evaluated if you develop a new, unexplained rash. Avoid close skin to skin contact including sex until you have been evaluated by your healthcare provider. If testing for monkeypox is performed, you will need to isolate at home away from other people and pets in your household until you get your test results.
If you test positive for Mpox isolate at home. If you have an active rash or other symptoms, stay in a separate room or area away from people or pets you live with, when possible. You may end isolation when the rash has completely healed.
Contact your health care provider. There are two vaccines for smallpox that can be used for Mpox. Jynneos vaccine is the main vaccine being distributed at this time. Vaccination is currently recommended for individuals who have been exposed to monkeypox. CDC recommends the vaccine be given within 4 days from the date of exposure in order to prevent onset of the disease. If given between 4–14 days after the date of exposure, vaccination may reduce the symptoms of disease, but may not prevent the disease.
JYNNEOS is licensed for a 2-dose series given at an interval of 28 days. In the setting of limited vaccine supply, DOH recommends prioritizing the administration of first vaccine doses rather than retaining inventory for second doses. This means that some people may have their second dose of vaccine delayed beyond 28 days until vaccine supply increases. Exceptions include people with moderate to severe immunosuppression, for whom the second dose should be administered as close to 28 days after the first dose as possible.
Post-Exposure Prophylaxis (PEP) l Vaccination after known exposure to Mpox
Expanded Post-Exposure Prophylaxis (PEP++) l Vaccination after known or presumed exposure to Mpox
Pre-Exposure Prophylaxis (PrEP) l Vaccination before exposure to Mpox
- CDC recommends that the vaccine be given within 4 days from the date of exposure in order to prevent onset of the disease. If given between 4–14 days after the date of exposure, vaccination may reduce the symptoms of disease, but may not prevent the disease.
- For those with previous smallpox vaccination who are exposed to Mpox, and who have not received the smallpox vaccine in the last 3 years, should consider getting vaccinated.
- Due to the EUA, those under the age of 18 can receive post exposure vaccination in accordance with Washington state law.
- If the individual develops symptoms of disease after the first dose is administered, it is not recommended for the individual to receive the second dose.
