There is no such thing as the middle stage of AIDS. AIDS can be categorized into acute stage, asymptomatic stage and AIDS stage with different symptoms.
1. Acute phase: usually occurs 2 to 4 weeks after infection, most patients may have fever, headache, vomiting, nausea, diarrhea, arthralgia, sore throat, skin rashes, and enlarged lymph nodes and other symptoms.
2. Asymptomatic phase: patients can enter this phase directly from the acute phase, or enter the asymptomatic phase directly without obvious acute phase symptoms, during which patients do not have any symptoms, and generally lasts for 6 to 8 years.
3. AIDS stage: patients may have fever, diarrhea and memory loss, headache and other symptoms that last for more than a month. There may also be various infectious diseases and tumors caused by low immunity.
There are large individual differences in the course of the disease and symptoms of patients. For patients, they should actively cooperate with doctors for treatment with a view to controlling the disease and improving the quality of life.
