Folliculitis is a relatively common skin disease that occurs in most people’s lifetime. It is mainly caused by bacterial infection, and the typical symptoms are localized skin redness, swelling, heat and pain, which usually resolve on their own within a few days. AIDS is an acquired immunodeficiency syndrome caused by HIV infection, which has a long incubation period of about 9 years on average, and most people do not have any symptoms during the incubation period, but only after they enter the AIDS stage will they have various symptoms, such as fever, night sweats, diarrhea, etc. To confirm the diagnosis of HIV infection, HIV-related antigen and antibody tests should be performed after the window period to clarify the diagnosis. Once the diagnosis is confirmed, treatment with antiviral drugs should be carried out.
