title: Difficulties in diagnosing group o human immunodeficiency virus type 1 acute primary infection.
abstract: We report a rare case of acute human immunodeficiency virus (HIV) type 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. The unequal performance of many of the serologic and molecular assays commercially available leads to delays in diagnosis and affects patient management.
