How many days does monkeypox fever last?

Fever generally refers to an elevated body temperature. In most cases, fever associated with monkeypox lasts for 1–3 days. The details are as follows:

Monkeypox is caused by the monkeypox virus and can be transmitted between animals and humans, as well as through secondary transmission among humans. The incubation period for monkeypox ranges from 5 to 21 days. After this period, patients enter a prodromal phase characterized by sudden onset of acute illness, including symptoms such as fatigue, headache, and muscle pain. Body temperature typically rises above 38.5°C and usually persists for about 1–3 days. This is followed by the rash stage, during which skin lesions progress through four stages: macules, papules, vesicles, and pustules. The entire course of the rash lasts approximately 2–4 weeks. A few days after vesicle formation, the lesions begin to dry and crust over; once the scabs fall off, scars may remain.

Monkeypox is contagious, so patients should strictly isolate themselves to prevent spreading the infection to others. Skin lesions such as vesicles and pustules require careful hygiene. Patients should wear clean, soft cotton clothing and avoid scratching the affected areas to prevent secondary bacterial infections. Adequate rest is essential. For fever management, physical cooling methods can help dissipate body heat. If body temperature reaches or exceeds 38.5°C, antipyretic medications such as ibuprofen capsules or acetaminophen tablets may be used under medical guidance to control fever and prevent febrile seizures.

Monkeypox is a contagious, self-limiting disease. Once diagnosed, patients must immediately isolate and receive symptomatic treatment accordingly.
