In the early stage of HIV, there is usually no specific rash. Some patients may present with red blotchy rash, petechiae, papules, etc., but most of the symptoms are atypical and not easy to be detected. After HIV enters the body, corresponding clinical symptoms will appear within 2 to 4 weeks. Fever is the most common, and some patients may have a rash, sore throat, nausea, vomiting, diarrhea, and arthralgia. The rash is not specific and may appear as a red macular rash, petechiae, or papules. Some patients may also have no obvious symptoms in the early stages and then enter an asymptomatic phase. If you have high-risk behaviors worrying about HIV infection, you should go to the hospital in time, early detection and early treatment, to avoid delaying the disease and causing adverse consequences.
