How effect Hiv in the body
The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which infects humans when it comes in contact with tissues such as those that line the vagina, anal area, mouth, or eyes, or through a break in the skin.
HIV invades cells of the immune system. The cells are called CD4 cells (also called T-cells or T4 cells), dendritic cells and macrophages. The infected helper T-cells are activated, they work to create new viruses. In addition, many helper T-cells are destroyed in the HIV replication process.
HIV infection is generally a slowly progressive disease in which the virus is present throughout the body at all stages of the disease. There are two stages of the infection Primary and secondary.
 Within weeks of infection, many people will develop the varied symptoms of primary or acute infection which typically has been described as a mononucleosis- or influenza-like illness but can range from minimal fever, aches, and pains to very severe symptoms. The most common symptoms of primary HIV infection are
fever,    aching muscles and joints, sore throat, swollen glands (lymph nodes) in the neck.
