The disease can be transmitted by dried small pox scabs and through materials the infected person has come in contact with. The virus is reproduced in the lymphoid tissue and released into the body. Virus reproduction begins when the virion comes into contact with a suitable host cell. The virus must interact with a receptor on the cell surface. The infectious cycle usually consists of two stages. The first stage makes the proteins necessary for the protein to form. The second stage forms the adult virion to start the attack on the body.

However, after a person has come across the disease and recovers from it they become permanently immune to the virus. Jenner later promoted the smallpox vaccination and ultimately wiped the virus clear out. Since then there has only been one case of smallpox but they are not certain that it really was the smallpox virus or just a clone of a chicken pox virus. Vaccinations only work depending on ones immune system if it is weak the vaccine will not take. The number of small pox infected countries gradually decreased. " In April 1978, WHO ( world health organization) officials announced the world's last known case of naturally occurring small pox had been found in Somalia in October 1977" ( Fetzer 513).
