Mpox: A Comprehensive Overview

Mpox is a viral zoonosis – a disease that can be transmitted from animals to humans. It is indeed caused by the mpox virus, which belongs to the orthopoxvirus family. Symptoms typically include a rash that can look like pimples or blisters, fever, headache, muscle aches, and swollen lymph nodes. while Mpox is usually not fatal, it can be serious, especially for individuals with weakened immune systems.The virus spreads through close contact with lesions, bodily fluids, respiratory droplets, and contaminated materials. Prevention strategies include vaccination, avoiding close contact with infected individuals, and practicing good hygiene.
