Small Pox :: essays research papers

Smallpox has been one of the most dangerous and deadly curses’ ever placed on humankind. Even illnesses as terrible as the plague, cholera, and yellow fever have not had such a universal effect. Smallpox is a parasitic virus (a virus destructive to the host) called variola. It’s considered to be a â€Å"crowd disease†, spreading only through people and requiring a large densely populated area to survive. If the virus is cut off from new host bodies it dies out. Smallpox is spread by what is called â€Å"droplet infection.† â€Å"Droplets† refers to body fluid that escapes into the open air such as moisture does when you sneeze. The smallpox virus also remains active on a human corpse for up to three weeks and can be passed through the dead host to the living host that way and also through items such as blankets and clothing, which remain infected for up to one year. Patients affected with smallpox will generally begin to show symptoms 9-12 days after exposure. These symptoms begin with depression, fever, rigors, vomiting, headache, and backache. In several cases patients have become disoriented and/or delirious. In other cases a distinct rash will begin to form on face, hands and legs in this phase. All others with begin to notice the rash within a few days. Following the outbreak of the rash on the face, it begins to spread to the chest. Cuts that have formed on face and body begin to turn into blisters and eventually into scabs during the healing process. The virus may attack the eyes, lungs, throat, heart and/or liver and lead to death. The first recorded smallpox outbreak occurred in 1350 BC during the Egyptian-Hittite war. The illness was passed from Egyptian prisoners to the Hittite population affecting both soldiers and civilians. Although it wasn’t until the late 1600’s that people in Europe and Asia accidentally discovered that those infected with smallpox through a scratch on the skin, suffered from a less severe form of the disease than those who contracted it through the respiratory tract. In the early 1700’s doctors began to store samples of smallpox pus and scabs in jars. If an outbreak occurred the doctor would make a small cut in a person’s arm and smeared the pus into the wound. This process of intentionally infecting a person with the smallpox virus in order to make them immune to the disease in the future was called inoculation.
