When HIV gets into a persons blood it attaches itself to a special type of white blood cells called as helper T-Lymphocytes. These Helper T- cells are crucial in defending the body against many infections. during all this the persons have no symptoms at all. They look and feel well. They may not know they now have the virus, but could pass it on to someone else through having sex, or by sharing needles or syringes.
Being HIV Positive is not the same as having AIDS. The HIV actually goes inside the white blood cells and lies their quietly. After about 5 to 10 years the HIV virus tricks the cell to start making the viral proteins, this results in the formation of a huge number of viral particles inside the white cells and eventually the cells burst releasing thousands of new viruses in the blood. The released viruses infecting new white cells This cycle goes on and on, and eventually the immune system of the body is overwhelmed and is no longer capable of fighting the infections.
Eventually the infected person may lose weight and become ill with diseases like persistent severe diarrhea, fever, or pneumonia, or skin cancer. He or she has now developed AIDS. People with AIDS can be helped with medicines for the different infections. At the moment though, in spite of much research, there is no cure for HIV or for AIDS and so, sadly, it is almost certain that people diagnosed with AIDS will die.
