Transmission of HIV aids
Earlier this month, but in 1981, the first cases of AIDS in the world in Los Angeles, USA and so this year marks 30 years since the onset of the disease.
The diagnosis was younger patients who an unusual pneumonia had caused their death. The picture was produced by a microorganism called Pneumocystis, now known as Pneumocystis jiroveci, and occurred in people who had an unexplained alteration of immunity.
In that first moment, “The New York Times ran a cover story under the title” A strange disease that alters immunity could become a threat. “At that point, just know that patients with this disorder have in common that they were young men who had sex with other men.
The first articles published on the subject, realized that perhaps it was a virus that altered immunity and could be transmitted sexually, by contaminated blood and vertical transmission (from mother to child).
Later, these findings were confirmed, i.e. establishing the three routes of HIV acquisition, until in 1983 it was able to identify the virus causing the disease: a retrovirus that causes immunodeficiency, leading to the disease Acquired Immune Deficiency Syndrome, AIDS. This first phase ends when between 1984 and 1985 shows the Elisa test, which identifies early as those infected with HIV.
