Clinical Overview
Professional summary
Mpox is a viral zoonotic pathology induced by the Mpox virus, an orthopoxvirus. Transmission occurs through direct contact with infectious lesions, scabs, or systemic body fluids.
Clinical presentation typically includes a progressive rash that evolves through several stages. While statistically rare, severe systemic complications can occur, necessitating high-authority immunization protocols for high-risk cohorts.
