History Of Chicken Pox Essay, Research Paper
HISTORY OF CHICKEN POXChicken pox, a highly contagious disease that strikes many people, is caused by the herpes zoster virus. The virus is transmitted by the respiratory system and carried in the bloodstream to all parts of the body. The main symptom is a rash that appears on the face and torso, but also on the extremities. The rash turns into blisters that itch like crazy ( I know from personal experience), that go away in a few days. The other symptoms are loss of appetite, fever, and headache. HISTORY OF TUBERCULOSISAn acute infectious disease of humans and some animals, tuberculosis is caused by bacteria of the genus Mycobacterium. One of the oldest known diseases, it was known as the great white plague. TB was one of the leading causes of deaths in adults until an antituberculosis drug was introduced in the 1940 s. The disease can remain dormant for years before becoming active. The typical symptoms are fatigue, night sweats and fever, loss of appetite and weight, and a constant cough. Hemorrhages may occur due to the destruction of lung tissue. The disease is spread through extended exposure to an infected person, because when the victim coughs infected droplets into the air, they can be inhaled by someone near by.
