I had a sex with a prostitute with condom but next day I got fever and cough does it is a symptom of HIV

Professional Assessment: The acute onset of fever and cough within 24 hours of protected sexual contact is more likely related to a common viral upper respiratory infection rather than HIV, as HIV's acute retroviral syndrome typically develops 2-4 weeks after exposure. Given the reported condom use during the encounter, the risk of HIV transmission would be extremely low (less than 0.1%), though other STIs should still be considered in the differential diagnosis. A thorough workup would include HIV testing at baseline and at 3 months post-exposure, along with screening for other STIs, and evaluation of the respiratory symptoms which could be due to seasonal viruses, COVID-19, or other common respiratory pathogens. While the patient's anxiety is understandable, immediate HIV testing would be recommended primarily for baseline documentation and peace of mind, as current generation HIV tests may not detect very recent infections within the "window period."

Based on the symptoms and timeline, this is most likely an unrelated upper respiratory infection rather than HIV, as HIV symptoms typically don't appear within 24 hours of exposure. Take acetaminophen (Tylenol) 500mg every 6 hours for fever and get plenty of rest and fluids. However, since there was a high-risk exposure, get an HIV test after 2-3 weeks for peace of mind, and in the meantime take over-the-counter cough medicine containing dextromethorphan for the cough symptoms.
