If you have AIDS at the age of 20, you can choose the appropriate treatment plan according to the stage of the disease. Due to the lack of effective therapeutic drugs for AIDS, treatment is mainly based on standardized antiviral and anti-infection therapy, generally after active standardized treatment, the survival period of patients can be prolonged, and some patients can even survive for a long time. 1. Acute stage: Generally, the amount of virus in the body rises sharply within 1-4 weeks after infection with HIV, and the immune system is damaged, resulting in swollen lymph nodes, fever, fatigue, appetite Decrease in appetite, dry cough, erythema of skin mucosa, itching of genital tract, headache and other symptoms. At this time, you should be promptly admitted to hospital for examination, isolation treatment, and active antiviral and anti-infection treatment to avoid aggravation of the disease; 2. Asymptomatic period: This period can last 2-8 years, generally without any clinical symptoms, but HIV can be detected in laboratory tests. It is important to note that as the immune system decreases, the asymptomatic stage is also prone to infection, so improving resistance and maintaining a happy mood can also reduce the risk of developing the disease. Treatment can be based on individual circumstances, using antiviral or combined antiretroviral treatment programs to inhibit the replication of HIV as much as possible, effectively control the progress of the disease and improve the quality of life; 3. AIDS stage: If the viral load in the patient’s body rises, it is easy to complicate a variety of infections and invade the internal organs, reproductive tract, nervous system, mucous membranes of the whole body, thus causing tuberculosis, sepsis, meningitis malignant tumors and other diseases. Prevention and early diagnosis should be done and opportunistic infections of AIDS should be treated in time to prolong life.
