More about mpox
Mpox, previously known as monkeypox, is an uncommon disease caused by the mpox virus. Mpox virus is in the same family of viruses as the variola virus that causes smallpox.
Prior to 2022, mpox was spread mostly through contact with certain animals. During the global mpox outbreak that began in May of 2022 we saw mpox mostly spread through close physical contact between people. Some populations were affected more than others, including gay, bisexual, and other men who have sex with men who had recent contact with a new partner or partners.
Mpox symptoms often include a rash that can look like pimples or blisters. The rash can appear on the face, inside the mouth, and on other parts of the body, like the hands, feet, chest, genitals, or anus. Symptoms develop approximately 12 days after a person has been exposed but may be as early as five days and as late as 21 days.
Other symptoms of mpox can include:
Some people do not report having symptoms before the onset of rash. In most cases the rash begins as a flat rash, then progresses to raised bumps which become filled with fluid (poxes). Eventually the rash crusts over and scabs develop. Some people may have only one sore, bump, or blister. This may look different from pictures you see online.
A person is infectious from symptom onset until scabs fall off and a fresh layer of healthy skin has formed. The illness can last for around two to four weeks.
Mpox is spread through direct and indirect contact with the virus.
Take the following steps to prevent or decrease your risk for getting mpox:
Visit Lower Your Risk for Mpox for more information about steps you can take to reduce your risks for getting mpox.
Vaccination is the best way to protect against mpox infection and is recommended for those who are at risk or have been exposed to a person who has mpox. The mpox vaccine is given as a two-dose series separated by 28 days (four weeks).
People who are at risk of mpox disease:
For more information, refer to CDC: Mpox Vaccine Recommendations. People exposed to a person with confirmed or probable mpox CDC recommends getting vaccinated within four days from the first day you were exposed to help prevent disease. If given between four and 14 days after exposure, vaccination may reduce the symptoms but may not prevent infection. Talk to your health care provider if it has been more than 14 days after exposure. Refer to CDC: If You’re a Close Contact for more information.
If you are at risk and would like to get vaccinated, start by contacting your primary health care provider. If you do not have a provider or your provider does not have vaccine, visit CDC: Mpox Vaccination Basics to search the CDC: Find Mpox Vaccines tool to find a vaccine provider or clinic that has reported they have vaccine available.
Make sure you are up to date with your mpox vaccination. It is possible to get mpox even after getting vaccinated, but getting both doses of the vaccine makes getting and spreading mpox less likely. The vaccine may also help make symptoms less severe and easier to manage, and may help protect you against severe infection, hospitalization, and death. For more information visit CDC: Mpox after Vaccination.
If you have a new rash, sore, pimple-like bump, or blister, get tested. Only people who have a rash can get tested for mpox. You may be asked questions about sexual activity/behaviors by your provider to determine if testing for mpox is necessary. The mpox rash may look like other sexually transmitted infections (STIs) such as syphilis or herpes so your provider may consider additional STI testing.
Consult with a health care provider. If you do not have a health care provider, consider one of the following free or low-cost testing sites:
There is no specific treatment for mpox, although treatment with an antiviral, Tecovirimat (TPOXX), may be recommended for people who are more likely to get severely ill, like patients with weakened immune systems. In certain situations, people who have been exposed to someone with mpox may benefit from receiving a mpox vaccine.
