For more than two decades, mankind has known an ode to one of the most terrible diseases of modern society - HIV. The human immunodeficiency virus has been considered by doctors as a separate disease since 1981. In 1983, the virus was first isolated from the blood of patients by the French researcher Luc Montagnier. And in 1987, the World Health Organization approved a new disease - HIV.
There is a certain misconception that AIDS and HIV are equivalent concepts. But this is actually not true. Once in the human body, the virus begins to multiply. It affects the so-called T-lymphocytes - blood cells that protect the human body from various microorganisms that can cause disease. The speed of this process varies greatly among people. So, many can be carriers of the virus for more than ten years, without experiencing any inconvenience. The biggest danger lies in the fact that a person, not knowing what is the carrier of the infection, infects others.
AIDS is the second phase of the disease. This period is already characterized by a variety of symptoms. Fever, fatigue, indigestion, rash, sweating, rapid weight loss, frequent sore throats are just a small part of the overall clinical picture of the disease. These signs should alert anyone, but they do not necessarily indicate AIDS.
The diagnosis of the virus is carried out using a blood test. This study with a high degree of probability can confirm or exclude the disease. And adherence to basic hygiene rules can reduce the likelihood of infection to almost zero.
The virus is contained exclusively in such body fluids as blood, breast milk, semen. In saliva, urine, feces and exhaled air, the amount of the pathogen is negligible and not enough for transmission. From this it follows that infection occurs when having sex with an infected person, repeated use of disposable syringes, from a sick pregnant mother to a child, with various medical procedures, which is now very rare. Through kissing, mosquito bites, communicating with sick people and sharing food, the disease does not spread.
Until now, there is no effective treatment for this insidious disease. But modern medicine is able to significantly slow down the course of HIV, which significantly prolongs the life of both carriers and sick people.
