Smallpox is an infectious disease. The virus that causes smallpox belongs to the poxvirus family, the genus orthopoxvirus, and the species variola virus. High fever, chills, vomiting, stomach discomfort, headache, back pain, and progressive rashes on the whole body are all symptoms of this infection. This disease shows a mortality rate of 2% or less. This virus spreads from natural disasters and some climatic conditions. It is host-specific to man and evenly distresses humans of all ages. This disease is considered the first infectious disease which was eradicated successfully from all over the world. In 1980, WHO declared the eradication of smallpox from the world. Variola was taken as a biological weapon in world-famous wars as well. The mode of transmission for smallpox is direct contact with lesions or through airborne respiratory droplet secretions.
