Today in class we finished up our teaching for the different diseases. Here are some notes on the diseases.
Cholera: is a bacteria, effects mostly babies and children, can be fatal, causes dehydration, caused by unsanitary water, symptoms are diarrhea, vomiting, cramps, and fevers, "cure" (is a way to treat the disease, not stop it completely) is made with sugar, salt, and clean water
HIV/AIDS: Human Immunodeficiency Virus / Acquired Immune Deficiency Syndrome
Virus that affects your immune system, No cure for for HIV/AIDS as of 2010, AIDS shuts down the immune system so you can't fight any illnesses, if you get sick, you cannot fight the disease and you will die, these days they give you drugs to fight the disease. HIV leads to AIDS. No visible symptoms. Transmitted by blood and body fluids.
Smallpox: is a virus, no known cure, vaccine developed in 1796, can only be spread by direct contact, easy to diagnose because shows spots on skins, is easy to trace because of this, is not known to be spread by insects or animals, global campaign against it in 1967 by World Health Organization, vaccinated people exposed to the disease, they invented a special needle that could be used over and over again for vaccination, became first major disease to be wiped out completely.
