The WHO declared MPOX a public health emergency. What it is, how it spreads, its symptoms, and the prevention measures available.
MPOX (formerly known as monkeypox) is a viral disease caused by a virus in the same family as human smallpox. First identified in primates in Africa, it has since spread globally, leading the World Health Organization to declare it a public health emergency of international concern in August 2024.
It spreads mainly through direct contact with an infected person's bodily fluids, through contact with contaminated surfaces or objects (clothing, bedding, towels), and zoonotically — from animals to humans — through bites, scratches, or handling meat from infected animals.
Early symptoms include fever, severe headache, muscle pain, fatigue, and swollen lymph nodes. A characteristic rash appears afterward, progressing through stages from spots to pus-filled blisters and scabs. The incubation period can range from 5 to 21 days.
Diagnosis is confirmed through clinical evaluation combined with a PCR test that detects viral DNA in samples from skin lesions. There is no specific antiviral exclusively for MPOX; treatment focuses on relieving symptoms, controlling fever, managing pain, and preventing secondary infections in the lesions.
Prevention relies on avoiding direct contact with infected people, not sharing personal items, and maintaining good hygiene practices. In Mexico, COFEPRIS approved the JYNNEOS vaccine in September 2024 as an additional prevention measure. If you have symptoms consistent with MPOX, the most important step is to seek medical evaluation, avoid close contact with others, and follow a healthcare professional's guidance.
