AIDS

Acquired immunodeficiency syndrome, most referred to by its acronym AIDS or AIDS is a disease that affects humans infected by HIV. They say a person has AIDS when his body due to the immunodeficiency caused by HIV, is not capable of providing an adequate immune response against infections that afflict humans.

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 level of CD4 T cells that attack the virus, falls below 200 cells per milliliter of blood.

HIV is transmitted through the following body fluids: blood, semen, vaginal secretions and breast milk [1].

The World Day against AIDS is celebrated on December 1.

The Royal Spanish Academy (RAE) takes the word AIDS in the twenty-second edition of his dictionary, [2] which can be used in lower case and capital letters. [3] The use of lower case is recommended by the Pan American Health, health agency for the Americas United Nations [4].
