Initial symptoms can include fever, headache, muscle aches, low energy, and swollen lymph nodes (similar to COVID or the flu) before progressing to a skin rash or lesions. The rash or lesions can also be found on the face, arms, and legs as well as in the mouth and around the genitals/anus.
For people who are fully vaccinated that acquire mpox, symptoms can be very mild and a noticeable rash or lesions are less likely to occur. However, among individuals who have been vaccinated, common symptoms reported include:
- proctitis (inflammation of the rectum)
- stomach cramps
- increased or constant need to go to the toilet
- severe lower back or body pain
- sore throat and/or mouth ulcers
- painful urination
Because many mpox symptoms resemble other STIs (for example herpes), it is important to contact your GP or local sexual health clinic and explain your concern that it could be mpox. Let them know about your symptoms when you make an appointment.

The incubation period (the time from infection to the onset of symptoms) of mpox is usually 7-14 days, but it can be as short as 1-2 days or as long as 21 days.
While symptoms are typically mild, for some people with moderate to serious cases mpox can be quite painful.
If you believe you have been exposed to mpox or suspect that you may have acquired mpox, speak to your GP or local sexual health clinic.
