HIV to AIDS • Remember HIV will attack and wipe out your immune system (T-Cells). • When an HIV positive persons T-cells count is below 200 (normal is 800-1500) & has an opportunistic infection present, they have AIDS. • An opportunistic infection is an infection caused by pathogens that usually do not cause disease in a healthy immune system. A compromised immune system, however, presents an "opportunity" for the pathogen to infect. (ex. A cold, sunburn….)
HIV • Variable incubation period months-years • HIV lives in the blood, semen, vaginal fluid and breast milk of an infected person. • 70 % of all new infections are by unprotected sex. Sharing needles is the second most common way it is transmitted. • Mother to child during birth and breast feeding are also ways of transmission.
HIV • Flu-like symptom. Known as a ‘wasting’ disease- rashes, weight loss, fever are common signs (for those that engage in risky behavior). • There are specific treatments but NO CURE. The end result will be death of the infected person.
Where did HIV Come From?Hunter Theory • A Hunter was exposed to SIV (monkey virus) while hunting or butchering a monkey. The SIV ‘morphed’ to HIV in the hunters body. The hunter is now infected with HIV. • Researchers believed this happened many times but the outbreak would die off in the small isolated village the hunter lived in. One time it took off like no other. • They believe that the transmission event that has caused the current pandemic of HIV happened around the 1930’s. From that single transmission event when 1 man was infected from 1 monkey HIV has gone on to spread person to person to approximately 80 million people. • Contributing factors – • The urbanization of Africa, cars trains and other forms of transportation aloud a person that lived in the bush or village to travel to more densely populated areas like cities. If an infected hunter were to travel to a city that person could no infect more people. • Unwitting vaccine transfer, during this time vaccine controls were vaccinating thousands of people a day for diseases like small pox and polio. The technique of using 1 needle to vaccinate many people would also expose many more people to HIV if someone getting the vaccine had HIV. • From testing saved blood samples researchers have found that first confirmed death from HIV occurred in 1959 in the Congo region of Africa (West Central Africa).
