Scientists believe that HIV Came from monkey blood in Brazil or Africa when people were eating a monkey and didnt cook it or clean it all the way. HIV is thearied to be dormant in monkeys because its not a whide spread noticable sickness, monkeys arent dying left and right, but on the other hand it would be abnormal for HIV in moneys for form into AIDS because monkeys dont have many sicknesses to fear. another theory is that just that one monkey could have had the first sign of HIV and because it was at the stage of AIDS it was too slow or weak to get away from its captors and consumed, thus sickening humans from wrong cooking or cleaning.
HIV
A mouth disease can't cause HIV.
A person with primary HIV would get a rash later on in the disease progression. Some people will have flue like symptoms when they first catch HIV.
HIV does not refer to a disease, but a virus that in-turn causes the disease AIDS. HIV is transmissible via the blood and saliva.
The autoimmune disease caused by the HIV virus is AIDS.
In essence it is both; the HIV infection occurs which leads to the disease AIDS.
The difference between HIV and AIDS is that HIV is the virus that causes the disease AIDS. You can be a carrier of the HIV virus and not contract the disease but you can infect others.
HIV is a virus; AIDS is a disease.
Lupus has nothing to do with HIV AIDS. Lupus is an autoimmune disease. HIV AIDS is an immunodeficienty disease transmitted by a virus.
A disease
HIV is the virus. AIDS is the disease caused by the virus. (So HIV is not actually a disease per se.) As an analogue - the H1N1 virus can cause the flu.
HIV infection or AIDS is the disease, which you have infection by HIV virus, that attacks disease fighting cells in the blood.
