Smallpox
Smallpox is an infectious disease caused by the variola virus, which is a member of the orthopoxvirus family. It is highly contagious and can be spread through contact with an infected person or contaminated objects. Smallpox was one of the most devastating diseases in human history and was responsible for millions of deaths before it was eradicated in 1980. Symptoms of smallpox include high fever, nausea, body aches, and a rash that develops on the face and body. The rash begins as raised bumps that eventually become pus-filled blisters that eventually scab over. Complications of smallpox can include dehydration, blindness, and even death. Vaccination is the only way to prevent smallpox infection, and vaccination is recommended for those who may be at risk of coming into contact with the virus.
