How can I tell if I’m infected with HIV?
The only way to determine whether you are infected is to be tested for HIV infection. You can’t rely on symptoms to know whether or not you are infected with HIV. Many people who are infected with HIV don’t have any symptoms at all for many years.
Similarly, you can’t rely on symptoms to establish that a person has AIDS. The symptoms associated with AIDS are similar to the symptoms of many other diseases. AIDS is a diagnosis made by a doctor based on specific criteria established by the Centers for Disease Control and Prevention (CDC).
