HIV (human immunodeficiency virus) is a sexually transmitted virus that can turn into AIDS (acquired immune deficiency syndrome). Certain cells in the body called CD4 cells are supposed to protect the body from infection. In HIV, these cells are decreased and the body becomes susceptible to a wide variety of infections. Specific symptoms of HIV include a fever, headache, sore throat and a rash, says the Mayo Clinic. Though there is no cure for HIV, there are several medications used to manage it.
