One month after contracting HIV, some patients may have no symptoms, and even if they do, the symptoms are not very obvious, or they may experience cold symptoms, rashes, and so on. 1. Cold and flu symptoms: About one month after being infected with HIV, patients may experience a series of symptoms similar to those of a cold. For example, fever, nausea and vomiting, dizziness and headache, sore throat, swollen lymph nodes, night sweats, muscle and joint pain, diarrhea and other symptoms. As the symptoms are not very obvious, they need to be distinguished from colds. 2. Rash: A small number of patients may have a rash, which usually grows on the arm area, manifested as a red maculopapular rash, usually accompanied by itchy symptoms, and may subside on its own. As the symptoms of HIV infection for one month are not typical, you should not judge whether you are infected with HIV by the symptoms, and you need to consult a doctor in time to confirm the diagnosis through systematic examination.
