	Abstract

We report a rare case of acute HIV-1 group O infection in a French Caucasian woman. Her sexual partner was secondarily diagnosed with HIV-infection and transmission was confirmed by phylogenetic analysis. Unequal performances of many serologic and molecular assays commercially available lead to delays in diagnosis and affecting patient management.
