Patients with AIDS do not have itchy heads, but have a variety of symptoms that occur at different times during the course of the disease. The acute phase of AIDS usually occurs about 2-4 weeks after the initial infection, and some patients may experience transient symptoms, including fever, headache, night sweats, nausea, vomiting, sore throat, swollen lymph nodes, etc., but not head itching. When the patient enters the AIDS stage, various opportunistic infections will occur due to the extremely low immune function, with Pneumocystis pneumonia being the most common, Cryptococcal meningitis, Candida albicans esophagitis, and herpes zoster, etc. There are no symptoms of head itching, so head itching is not a specific symptom of AIDS patients.
