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.

airborne respiratory droplet secretions. .. View More»
