On this day in 1979 Smallpox an acute contagious disease caused by the variola virus, a member of orthopoxvirus family was declared eradicated. Smallpox was one the most devastating diseases known to humanity.

Smallpox was eradicated worldwide as a result of a global immunization campaign. Here’s what’s scary. Samples were kept for research purposes, leading to concerns that smallpox could be used as a biological warfare agent.

Considering latest acts of terrorism I’m concerned. There is no cure or treatment for smallpox.
