Inform yourself about HIV

You know it's the AIDS (HIV).?. It is a disease that affects people who have been infected with human immunodeficiency virus (HIV). It is said that someone has AIDS when his body due to the immunodeficiency caused by HIV, can not provide an adequate immune response against infection .................. .. Whence comes?

HIV is related to other viruses that cause AIDS-like disease. It is believed that this virus was transferred from animals to humans in the early twentieth century. There are two different viruses causing AIDS in humans, HIV-1 and HIV-2. The first reservoir species are chimpanzees, whose virus itself, the SIVcpz, is derived. HIV-2 derived from the SIVsm, typical of a species of monkey in West Africa. In both cases the interspecies transmission has occurred several times, but the current pandemic is extension of the group M HIV-1, as estimated from an infection in Central Africa, where the virus expresses the maximum diversity in the first half of the twentieth century ...................... Women and AIDS

According to the United Nations Fund for Women (UNIFEM), although HIV infection began focusing primarily on men, today, women account for 50% of people infected with HIV. Even in regions like sub-Saharan Africa, women represent 60% of the total HIV population. Symptoms and signs of AIDS symptoms of HIV and AIDS vary depending on the stage of infection. When a person is first infected with HIV is probably not present any symptoms, but is more common to have flu or flu symptoms for two to six weeks after being infected. But despite the signs and symptoms of an initial infection - which include fever, headache, sore throat, swollen lymph glands and rash - are similar to a variety of diseases, will not realize it has been infected by HIV. Even though no symptoms of the disease can still spread the virus to others. Once the virus enters the body, the immune system act. The virus multiplies in lymphocytes and slowly begins to destroy T cells - white blood cells that coordinate the immune system.

The only cause of transmission is the exchange of bodily fluids, including blood and genital secretions. The HIV virus can not be transmitted by breathing, saliva, casual contact by touching, shaking hands, hugging, kissing on the cheek, mutual masturbation with another person or sharing items like glasses, cups or spoons. Instead it is theoretically possible that the virus is transmitted from person to person through kissing mouth to mouth, if both people have bleeding wounds or ulcerated gums, but that case has not been well documented and is considered very unlikely, since saliva contains concentrations much lower than for example semen, saliva and also because it has antiviral properties that make destroy HIV.
