People who are infected with HIV can look and feel healthy and may not know for years that they are infected. However, they can infect other people no matter how healthy they seem. Some of these diseases can kill them. Signs of HIV infection are like those of many other common illnesses, such as swollen glands, tiring easily, losing weight, fever, or diarrhea.
Different people have different symptoms.
HIV is in people's blood, semen, vaginal fluid, and breast milk. The only way to tell if someone is infected with HIV is with a blood test. There are treatments that can keep infected people healthy longer and prevent some diseases that people with AIDS often get. Research is ongoing. HIV slowly makes an infected person sicker and sicker.
