The article discusses a study on the trends in human immunodeficiency virus (HIV) diagnoses among men who have sex with men (MSM) in New Zealand from 1996 to 2008. The study found that annual HIV diagnoses between 1996 and 2000 were low, but a dramatic increase occurred from 2001 and 2005 which continued at a stable phase from 2006 to 2008. HIV infection acquired overseas accounted for 28.6% of diagnoses. Individuals diagnosed with HIV between 2001 and 2005 were mostly 30 to 39 years old, lived in the Northern region that encompass Auckland and of non-European ethnicity. The authors conclude that a rise in locally acquired HIV infection significantly contributed to the surge in HIV diagnoses among MSM.
