The symptoms of the acute phase of AIDS can actually be very non-specific, with many people not showing any obvious symptoms. Some people, about two to three weeks after being infected with the HIV virus, may experience a series of symptoms such as fever, rash, sore throat, swollen and painful lymph nodes, diarrhea, etc. Some might only exhibit one or two of these signs. In reality, the symptoms are often not very typical. The main consideration should be the patient's high-risk behaviors, along with testing for HIV antibodies or HIV nucleic acids, as these can be used to diagnose AIDS.
