HIV infection is a disease caused by the human immunodeficiency virus, acquired immunodeficiency syndrome characterized by contributing to the emergence of secondary infections and malignancies in connection with a profound inhibition of the body's property. HIV infection has diverse variants of the course. The disease may last for a few months or stretch up to 20 years. The main method of diagnosis of HIV infection is the detection of specific antiviral antibodies and viral RNA. Currently the treatment of patients with HIV is antiretroviral drugs buy zithromax 500mg able to reduce the reproduction of the virus.

Today, the world celebrates the HIV infection, the incidence of the world's population, especially in Eastern Europe is growing steadily.
Human immunodeficiency virus-containing DNA, refers to the genus Lentivirus family Retroviridae. There are two types: HIV-1 is a major activator of HIV infection, the cause of the pandemic, AIDS development. HIV-2 - less common type, occurs primarily in West Africa.
HIV - virus unstable, quickly die carrier body is sensitive to the effects of temperature (reduces infectious properties at 56 ° C, are killed after 10 minutes while heating to 70-80 ° C). Good storage in blood and blood products prepared for transfusion. The antigenic structure of the virus is very changeable.
The reservoir and the source of HIV infection is a person: who suffers from AIDS and the media. Natural reservoirs of HIV-1 have been identified, it is believed that the natural host in nature are wild chimpanzees. HIV-2 is transferred to the African apes. Susceptibility to HIV can not be observed in other animal species.
The virus is found in high concentrations in the blood, semen, vaginal secretions and menstrual gland secretions. It may stand out from the breast milk, saliva, lacrimal secretions and cerebrospinal fluid, but these bodily fluids are less epidemiological risk.
The probability of HIV transmission is increased in the presence of lesions of the skin and mucous membranes (trauma, bruises, cervical erosion, stomatitis, periodontal disease, and others.)
HIV is transmitted by blood-borne and biokontaktnogo mechanism in a natural way (through sexual contact and vertically from mother to child) and artificial (primarily realized at gemoperkutannom transmission mechanism: the transfusion, parenteral administration of substances, traumatic medical procedures).
Risk of HIV during a single contact with the carrier is low, regular sexual contact with an infected him greatly increase. Vertical transmission of infection from mother to child can be sick like in utero (via placental barrier defects), as well as in childbirth, the child in contact with the mother's blood. In rare cases, fixed postnatal transmission through breast milk. The incidence of children infected mothers have reaches 25-30%.Parenteral infection occurs with injections using needles contaminated with the blood of HIV-infected individuals with transfusion of contaminated blood, non-sterile medical procedures (piercings, tattoos, medical and dental procedures, generating tools without proper treatment).
Contact-household transmission of HIV is not transmitted. Human susceptibility to HIV infection - high. The development of AIDS in people older than 35 years, as a rule, takes place in a short period of time after infection. In some cases, there is immunity to HIV, which bind to specific immunoglobulins A, present at a genital mucosa.
