It's not all swine flu...are we missing opportunities to diagnose primary HIV infection in patients with flu symptoms?
The advantages of diagnosis of primary HIV infection (PHI) for the individual and public health are well documented. However, symptoms of HIV seroconversion are often not recognized by health-care professionals. Also, symptomatic patients themselves often do not present to health-care services. With the emergence of H1N1 infection, many patients with flu-like symptoms are seeking medical advice. Currently in the UK, the management of H1N1 is in the treatment phase, that is, patients are diagnosed and treated for H1N1 influenza based on clinical observation rather than laboratory testing. Symptoms of H1N1 infection are often similar to those of PHI. We present two cases of men who have sex with men from Brighton, UK presenting to general practice and accident and emergency with flu-like symptoms. Both were initially diagnosed on clinical grounds with H1N1 infection and treated empirically with antivirals but were later confirmed to, in fact, have symptomatic PHI. It is important in high-risk patients with flu symptoms attributed to swine flu infection, that PHI is also considered and excluded.
