What is AIDS? Virus? Disease? Where did AIDS come from? Social videos on TV and radio frighten us with this term and call to fight it.
First of all, it is worthwhile to understand that AIDS issyndrome of acquired (as a result of some disease) immunodeficiency. They do not get infected, because it's not some kind of bacterium, but a syndrome. In turn, the syndrome is a combination of any symptoms arising against a background of a disease, for example, HIV. More often than not, the creators of commercials on a social subject by this term mean just HIV, that is, the human immunodeficiency virus. For this reason, it would be more correct to ask "where did AIDS come from?", But "where did HIV come from?". So where did this virus come from?
But since many people often ask at the forums: "Where did AIDS come from?", Then we, perhaps, will answer this question.
The first cases of the syndrome acquiredImmunodeficiency was detected in drug addicts and homosexuals. Shortly thereafter, it was found that among people with this syndrome, there are often those who have been previously transfused with blood or blood products. And so, in the early eighties of the 20th century, American scientists R. Gallo and M. Essex were the first to suggest that all cases of a decline in the functions of the immune system that can not be treated are a consequence of the disease. In their opinion, this disease is caused by a kind of retrovirus that causes a certain type of leukemia in an infected person.
Studies that were conducted a littlelater, showed that AIDS develops in a person who previously contracted HIV. This virus affects only one group of cells involved in cellular immunity, T-lymphocytes. First, it only disrupts the functions of these cells, and then completely destroys them. For this reason, the human body becomes vulnerable to various microorganisms - protozoa, viruses and fungi. In addition, a significant weakening of immunity in the future provokes the development of a variety of malignant tumors.
In general, the question of where AIDS first appeared,we answered. It is clear that the origin of AIDS is due to the human immunodeficiency virus. And it would be wrong to say that HIV is the causative agent of AIDS. This is one of the stages (last or terminal). But where did this virus come from?
There are several theories about its origin:
The theory of Robert Gallo.This scientist believes that the original carriers of HIV infection were green monkeys living in Africa. At some point, a dangerous retrovirus could overcome the interspecies barrier and was passed on to people. In addition to the green marmosets, some other primate species, such as African Mangabit and chimpanzees, also fell into the risk group, as they had antibodies to HIV in their blood. But where does this retrovirus come from monkeys, while no one knows.
HIV is a mistake of scientists.Some believe that this deadly virus is the result of an unsuccessful experiment in which scientists in the seventies of the 20th century tried to create an inoculation against hepatitis and poliomyelitis. It was at this time in the US were the first recorded cases of AIDS in humans. By the way, vaccines against poliomyelitis and hepatitis are created precisely from the biological material of chimpanzees. And then you can not help noticing the connection with the previous theory.
HIV - there is no such disease!There is antiretroviral therapy, which later causes a person AIDS. It turns out that HIV is just a fairy tale of pharmaceutical companies that want to make more money in this way.
HIV is a biological weapon created by American scientists in order to undermine the position of the USSR in the world.
