Smallpox
Smallpox is a serious viral infection caused by the variola virus. It spreads through direct contact or respiratory droplets and causes flu-like symptoms followed by a distinctive rash that develops into fluid-filled blisters. Smallpox can lead to severe complications and has a high mortality rate. It was a major health threat until a successful vaccination campaign led to its global eradication in 1980. The last natural outbreak occurred in 1977, and today, the virus is stored in secure laboratories for research purposes. Vaccination is no longer routine, as smallpox is considered eradicated.

Smallpox is a contagious disease caused by the variola virus, characterized by fever and a distinctive rash that develops into pus-filled blisters. It was historically severe, causing high mortality rates, but has been eradicated since the late 20th century through a successful global vaccination campaign led by the World Health Organization. Smallpox is unique because it is the only human disease to be completely eliminated, showcasing the effectiveness of vaccination. Although no longer a threat to public health, smallpox remains a subject of interest for research and biosecurity due to its potential as a bioterrorism agent.
