What is AIDS?
AIDS: Acquired Immunodeficiency Syndrome (AIDS) is,
in fact, a group of diseases. The number of defensive T cells in the body is drastically reduced, resulting in the appearance of various opportunistic diseases caused by bacteria, fungi, etc. A total of more than 20 diseases take advantage of the vulnerability of those affected
by AIDS. HIV: the virus of
human immunodeficiency The AIDS disease is caused by the human
immunodeficiency virus. All viruses, both HIV and any other virus, are very simple particles. They have genes that contain information to make their own copies, but viruses do not have enough mechanisms to reproduce themselves. What they do is take advantage of the machinery of the cells that infect them to reproduce: the virus enters the patient’s cell, initiates their reproductive mechanisms, and thousands of new viruses are created where originally there was only one virus. Each of these thousands of new viruses in the same way infects so many other cells of the patient.
This is how the flu works, for example, until the patient's body reacts, creates specific defense cells, and fights the virus.
HIV, however, does not infect any cell in the body: it infects precisely the cells responsible for the defense response of our body. It attacks T lymphocytes.
The consequence is very serious: the body cannot cope with HIV or other common diseases; in the end, the patient dies of various ailments if not treated.
When a person becomes infected with the virus, symptoms do not appear until 5 to 10 years have passed. During this time, we talk about people who are HIV-positive. After this time, symptoms usually appear, and then it is said that this person is affected by the AIDS disease.
