ENFERMEDAD DEL VIH SIDA

AIDS (AIDS, which stands for acquired immunodeficiency syndrome, AIDS in English) is a disease that affects humans infected by HIV (human immunodeficiency virus). They say a person has AIDS when his body due to immunosuppression caused by HIV, is not capable of providing an adequate immune response against infections that afflict humans. It is said that this infection is incontrovertible.Note the difference between being infected by HIV and suffering from AIDS. A person infected with HIV is HIV positive and goes on to develop a cadre of AIDS when their CD4 T cell levels (which are the type of cells that attack the virus) falls below 200 cells per milliliter of blood.HIV is transmitted through body fluids (such as blood, semen, vaginal secretions, breast milk). [1] The World Day against AIDS is celebrated on December 1.
