Smallpox is an extremely
infectious and powerful disease. It is caused by variola virus. There are usually two types of smallpox. They
are variola major and variola minor, each of which gives immunity against the
other. Variola minor is weaker and is found mainly in
South America and
Smallpox is a contagious disease, which explains its ability to bring about large number of epidemics. The variola virus is contracted from direct contact with individuals infected with the disease. We can also get infected from objects used by another smallpox victim (books, blankets, utensils, etc.). The respiratory region is the usual entry point for the variola virus into a human being.
There is no treatment for smallpox yet. The only treatment is support for the victim, trying to keep the patient as comfortable as possible. Antibiotics are prescribed to prevent secondary bacterial infections.
