title: [Primary HIV infection].
abstract: Up to 70% of individuals with primary HIV infection will develop symptoms of an acute illness. The most common symptoms reported are fever, generalized lymphadenopathy, arthralgia and myalgia, headache, pharyngitis, enanthema, skin rash, diarrhoea, and mucocutaneous ulcerations. More rarely, oesophageal candidiasis, meningoencephalitis, rhabdomyolysis and epiglottitis have been reported. The diagnosis of the acute HIV infection syndrome can be established by demonstrating antibodies to HIV or by demonstration of HIV antigen positivity. Detection of virus through culture or PCR may prove to be more sensitive, but are not yet used as routine methods. The course of the primary infection has prognostic importance for the subsequent course of HIV infection. This probably reflects the importance of both the viral phenotype and of the initial immune response to HIV. Primary HIV infection should be considered in any patient with possible exposure to HIV presenting with fever of unknown cause.
