AIDS History – The Hypotheses of the Rise of HIV

The first cases of deaths from the unknown disease, followed by weight loss, fatigue, declines, were noticed in the USA, Sweden, Tanzania, and Haiti in late 1970s, but some scientists think, that the disease appeared earlier. According to some reports, the first infected patient died of AIDS in the Republic of the Congo in 1959.

One of the first officially registered cases of AIDS was identified in the USA in June 5th, 1981, when 5 cases of pneumocystosis (severe pneumonia) were diagnosed in young homosexuals. It being known earlier that this disease has been diagnosed in immunocompromised people: old people, chronically ill persons and dysmature infants. Later scientists registered young people with Kaposi’s sarcoma, a rare form of cancer. This disease had been marked in the group of people, who took the medicaments, weakened the immune system.

In spite of hard therapy, most of patients died. Scientists had to conclude that diseases, suppressing immunity, combined common features. Such combination of diseases was named AIDS, acquired immunodeficiency syndrome.

But in 1983 scientists found the virus in enlarged lymph nodes which in 1986 was called HIV, human immunodefficiency virus. It was determined later that the frozen samples of blood serum, taken from the continent of Africa in 1960s, contain HIV antibodies. It was proved that the virus spreads through all liquid media (in different concentration): blood, sperm, breast milk etc. Since 1985 samples of donated blood and preventive examinations of patients have been taking everywhere to determine containing of HIV antibodies in blood.

1985. In addition to HIV-1, having been registered in the USA and Europe, less pathogenic and much less widespread virus, called HIV-2, was found on the territory of West Africa. World AIDS pandemic is concerned with the virus of the first type.

In 1987 the first AIDS medicine azidothymidine was tested and approved. It could slow down the development of the disease in patients with symptoms of HIV in men and in women of all ages.

1 December, 1988 is World AIDS Day.

To work with HIV-infected patients is very dangerous. As of early 1990 there were 4500 HIV-positive health care professionals (dentists, surgeons etc.).

2000. The last year of XX century. Every 5 seconds the infection affects a new victim. Every 8 minutes a new person dies. You may see how it looks like on the page “”. Between HIV and AIDS are more than 36 100 000 people.

New theories and hypothesizes of AIDS origins are intensively developing, particularly:

As the saying goes, the history of HIV infection is being written by our entire generation, but will it be read? Who knows!
