The exact duration of fever with HIV infection cannot be generalized, and not all HIV-infected patients will have fever symptoms. Acute symptomatic HIV infection is characterized by fever, swollen lymph nodes, sore throat, rash, myalgia/arthralgia, diarrhea, and headache and is often described as a mononucleosis-like illness. However, up to 60% of people with primary HIV infection are asymptomatic. Fever is not a unique symptom of HIV and is not specific, so you cannot rely on fever and how long it has been present to determine if you have HIV. If you are infected with HIV, it is recommended that you go to a regular hospital as soon as possible to complete the relevant examinations, such as HIV antibody test, and take anti-HIV drugs, such as lamivudine, nevirapine, ritonavir, raltegravir, etc. under the guidance of a professional doctor to carry out standardized treatment. During the period of infection, one should avoid having sex with others and do a good job in preventing the spread of HIV, so as not to threaten the health of others.
