Smallpox Research Paper

Smallpox Agent
Smallpox is a disease caused by the variola virus, a member of the orthopoxvirus family. It was one of the world's most devastating diseases known to humanity. The last known natural case was in Somalia in 1977. It was declared eradicated in 1980 following a global immunization campaign led by the World Health Organization.
Symptoms
High fever,chills,headache,severe back pain,abdominal pain,vomiting.
These symptoms would go away within two to three days. Then the person would feel better. However, just as the person started to feel better, a rash would appear. The rash started on the face and then spread to the hands, forearms, and the main part of the body. The person would be highly contagious until the rash disappeared. …show more content…
By the end of the first millennium of the Christian era, it had spread to all the densely populated parts of the Eurasian continent and along the Mediterranean fringe of north Africa. It became established in Europe during the times of the Crusades.. Transported across the Atlantic by Europeans and their African slaves, it played a major role in the conquest of Mexico and Peru and the European settlement of north America. Variolation, was devised as early as the tenth century. In 1798 this practice was supplanted by Jenner's cowpox vaccine. In 1967, when the disease was still endemic in 31 countries and caused ten to fifteen million cases and about two million deaths annually, the World Health Organization embarked on a programme that was to see the disease eradicated globally just over ten years later, and the world was formally declared to be free of smallpox in May 1980.
Social, biological and economic effect
Overcrowding in an area lead to many diseases where livung conditions and hygiene are sub standard.Decreased investment came the resurgence of known infectious diseases in industrialized countries.
Eradication problem
The central challenge to viral eradication is that, once HIV genetic material is incorporated into an infected cell, it persists throughout the remainder of the cell's lifetime. Current antiretroviral drugs neither kill these latently infected cells nor eliminate the viral genetic material within
