The early stage of AIDS mostly refers to the acute stage, which is characterized by non-specific symptoms such as fever, sore throat, swollen lymph nodes and rash. Male AIDS is caused by the infection of human immunodeficiency virus, which can be divided into acute stage, asymptomatic stage and AIDS stage. 1. Acute phase: refers to 2 to 4 weeks after infection with the virus, clinical symptoms mainly include fever, rash, headache, nausea, vomiting, myalgia, lymph node enlargement, etc. The above symptoms lack of specificity, and can generally subside within one month. 2. Asymptomatic period: it can be transferred to this period from the acute stage, or enter this period directly after infection. During this period, patients basically do not have any symptoms, or only have swollen lymph nodes. 3. AIDS stage: This is the final stage of the infection, and common symptoms include persistent fever, weight loss, enlarged lymph nodes, etc. As the patient’s immune system is severely impaired and may be combined with a variety of diseases, such as opportunistic infections and tumors, etc., the patient will also have symptoms of the corresponding diseases. If a man suspects that he is infected with HIV, it is recommended that he consult a doctor in a timely manner to clarify the target and follow the doctor’s instructions for standardized treatment.
