Understanding Smallpox: History and Impact

Smallpox, one of the deadliest diseases, has a history dating back to the 3rd century BCE. It spread globally with civilization growth, causing over a billion deaths. The variola virus, part of the poxvirus family, is responsible for smallpox. It spreads through airborne droplets and infects the body, leading to various symptoms. Recovery provides immunity, and smallpox was eradicated by vaccination, a major medical triumph.
