A 25-year-old female presents with flu-like symptoms, including fever, headache, and sore throat, and mentions a recent sexual encounter during which a condom was not used. What are the potential considerations?
The symptoms could indicate a wide range of conditions, from common flu to mononucleosis. However, given the recent unprotected sexual encounter, there's a possibility this could be an acute HIV infection, often known as seroconversion illness, which can present similarly to flu or mono. The patient should be tested for HIV and advised to get retested after three months, given the window period during which antibodies to HIV may not be detectable.
