HIV AIDS

Human immunodeficiency virus is a lentivirus (a member of the retrovirus family) that causes Human immunodeficiency (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infection. Infection with HIV occurs by the transfer of blood, semen vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. The four major routes of transmission are unsafe sex, contaminated needles, breast milk, and transmission from an infected mother to her baby at birth {perinatal transmission}. Screening of blood products for HIV has largely eliminated transmission through blood transfusions or infected blood products in the developed world. The initial infection with HIV generally occurs after transfer of body fluids from an infected person to an uninfected one. The first stage of infection, the primary, or acute infection, is a period of rapid viral replication that immediately follows the individual's exposure to HIV leading to an abundance of virus in the peripheral blood with levels of HIV commonly approaching several million viruses per mL. A strong immune defense reduces the number of viral particles in the blood stream, marking the start of secondary or chronic HIV infection. The secondary stage of HIV infection can vary between two weeks and 20 years. During this phase of infection, HIV is active within lymph nodes, which typically become persistently swollen, in response to large amounts of virus that becomes trapped in the follicular dendritic cells (FDC) network The HIV virus cannot be destroyed and lives in the body undetected for months or years before any sign of illness appears. Gradually, over many years or even decades, as the T cells become progressively destroyed or inactivated, other viruses, parasites or cancer cells (called "opportunistic diseases") which would not have been able to get past a healthy body's defense, can multiply within the body without fear of destruction. Commonly seen opportunistic diseases in persons with HIV infection include: pneumocystis carinii pneumonia, tuberculosis, Candida (yeast) infection of the mouth, throat or vagina, shingles, cytomegalovirus retinitis and Kaposi's sarcoma. HIV is a fearful disease; HIV is very difficult to cure it is a virus that mutates the body; if one cell infects the other that infects more until the entire body infected. Because of that, vaccine would be more probable. Before vaccine has not been created is because there are hundreds of strands would be very difficult. Recently I had the chance to talk to a brilliant doctor at Yale med who is working on the cure, and he explained that they find out a treatment for HIV. They are experimented HIV peoples, it’s a success. If you want to know more information about HIV please logon to http://www.hivend.com .
