Hi doctors,what are the "flu like symptoms" usually associated with syphilis or hiv normally like? would someone feel noticeably unwell? would a mucus chesty cough and stuffy nose but associated with either? thank you in advance?

Good question -- there's a lot of confusion on this. Influenza symptoms often include cough and nasal congestion, but acute HIV infection (acute retroviral syndrome, or ARS) does not. The "flu like" symptoms of ARS are fever, muscle aches, and generally feeling unwell, but not cough, stuffy nose, etc. Syphilis rarely causes any of these; its symptoms are not commonly called flu-like.
