How the HIV virus attack?

The HIV virus was first discovered in 1981  when homosexual men first had symptoms of a disease that were quite different from other viral infections. Full blown symptoms of the disease which are now indicative of AIDS were first described along with an unusual type of lung infection, weird skin tumors and upon laboratory testing of their blood samples, have revealed a significant decrease in CD4 cells which are useful in fighting infections. The HIV virus was soon seen in many countries in Europe and in Africa and by the year 1983 researchers have described the make-up of the virus that causes AIDS plus the actual definition of AIDS which is the “development of a low CD4 count  or any one of a long list of complications of HIV infection”
