Features of AIDS AIDS

(Acquired Immune Deficiency Syndrome) is a disease caused by chronic and prolonged damage to the immune system (defense system) to the human body caused by a virus known as HIV (in English: Human Immunodeficiency Virus). AIDS is a condition called Syndrome, and which, on the gradual destruction of our immune system, microorganisms usually inhabit our body without causing harm or cause minimal damage, they become highly dangerous because they spread and assault our bodies to be the answer diminished our immune system, thus causing a variety of diseases (diarrhea boxes, atypical pneumonia, cancer, tuberculosis, etc.). Our immune system begins to be damaged due to virus replication of HIV, and that, when divided into one of the key cells of our immune system (among others) called T lymphocytes emigrating from the cell causes its death. On the other hand as the virus divides and destroys T cells, the amount of virus in the blood begins to increase and be available to continue and further destroying infected cells. That is why it is called Immune deficiency because a deficiency in the action of the defense system, mainly by the destruction of CD4 + T cells. The word? Acquired? comes from the fact that there are diseases in humans, not very frequent, but for various factors, some of them caused by errors in genes (where information is stored for transmission to the offspring), produce low response to situations attacks by microorganisms by our defense system similar to those produced by the HIV virus, but in this case are not acquired but are due to errors the agency itself.
