After HIV infection, it can be divided into acute phase, asymptomatic phase and AIDS phase. Since each patient has a different body constitution and is infected with a different number of viruses, the time for symptoms to appear is also different. The acute phase usually occurs about 2-4 weeks after the initial HIV infection, and some patients may develop viremia and acute damage to the immune system, which causes clinical symptoms. The symptoms include fever, general malaise, headache, night sweats, nausea, vomiting, and skin rash, which usually subside within a month. After the acute phase, patients enter the asymptomatic phase, and some patients enter the asymptomatic phase directly after infection. During this period, patients have no clinical symptoms or only swollen lymph nodes. The duration of the asymptomatic phase can be as short as a few months or as long as several decades. After entering the AIDS stage, the patient’s immune system is severely impaired, and may be combined with various infections or tumors, thus showing symptoms of the corresponding diseases. If you have high-risk sexual behaviors or other high-risk factors that make you susceptible to HIV infection, you should go to the hospital in time to complete the examination and find out whether you have HIV infection or not.
