Mpox rash
Mpox rash
Mpox is a viral infection that causes fever, fatigue, muscle aches, and a painful rash. The mpox rash may involve part or all of the body. Once it appears, the rash goes through several stages.
Stage 1: Macules - flat, distinct, discolored areas of skin
Stage 2: Papules - raised spots on the skin that are less than one centimeter wide
Stage 3: Vesicles - small fluid-filled blisters on the skin
Stage 4: Pustules - small, inflamed, pus-filled, sores (lesions) on the skin surface
Stage 5: Scabs - hardened crusts of blood that form over sores, which help protect the skin as it heals
Mpox lasts 2 to 4 weeks. You are no longer contagious only after all symptoms are gone, scabs have healed, and new skin has formed.
