The acute phase of AIDS needs to last about 1-3 weeks. Most patients have mild clinical symptoms and do not need special treatment. If the patient’s body temperature is high, antipyretic drugs can be used appropriately. The main symptoms of the acute phase of AIDS are fever, sore throat, fatigue, nausea, vomiting, diarrhea, pain in the limbs and joints, and enlarged lymph nodes. There is no way to distinguish the acute phase of AIDS from other clinical symptoms caused by viral infections. If you are a high-risk group, you need to be alert to AIDS if the above symptoms appear after 2-4 weeks of high-risk behavior, and you need to do relevant antibody tests to clarify.
