Three months after HIV infection, most patients in this time period do not have any uncomfortable symptoms, and a small percentage of patients show only slight weakness. Therefore, the clinical manifestations of patients at this stage are not typical, and some patients at this stage also need to be treated with antiviral therapy. It is necessary to go to the local CDC for the examination of HIV count and CD4 cells and other related indicators. If antiretroviral therapy is indicated, medication should be taken in a timely manner. At this stage, because the infection is relatively short, most patients do not have opportunistic infections, so only regular antiviral treatment is needed. After taking antiretroviral drugs, it is necessary to monitor the adverse drug reactions and the change of HIV count to assess the efficacy.
