Symptoms of new HIV infection refer to the acute infection period, which occurs around 2-4 weeks after HIV infection. The main symptoms are flu-like symptoms, such as fever, sore throat, rash, diarrhea, muscle aches and pains, and enlarged lymph nodes. The clinical symptoms of most patients are not very serious and do not require special treatment, and will disappear on their own after about 1-3 weeks. After the acute infection phase, the patient enters the asymptomatic phase, in which there are no symptoms of discomfort. The diagnosis of AIDS cannot be made solely on the basis of the symptoms, and a screening test for relevant antibodies is required. If the antibodies are positive, further confirmatory tests are needed to clarify the diagnosis. If the antibodies are negative and the window period has passed, AIDS is basically ruled out.
