This article presents data on HIV testing activity in France from 2003 to 2010, based on the LaboVIH survey, and on newly diagnosed HIV-positive cases, based on mandatory reporting of HIV infection and virological surveillance conducted by the National HIV Reference Center. The number of HIV serology tests performed in France has remained stable since 2006, at approximately 5 million per year. In 2010, the number of confirmed positive serology results is estimated at approximately 10,800. The proportion of positive serology results per 1,000 tests is significantly higher in Île-de-France, French Guiana, and Guadeloupe than in other regions. The number of people who learned of their HIV-positive status in 2010 is estimated at approximately 6,300 (95% CI [5,914–6,616]), a figure that remained stable compared to 2009. This number has increased since 2003 among men who have sex with men. Very late diagnosis (<200 CD4/mm³ or AIDS stage) accounted for 30% of diagnoses in 2010, and early diagnosis (>500 CD4 without AIDS) for 36%. Community-based practitioners make more early diagnoses than hospital-based physicians. The widespread implementation of screening and its repeated offer to those most at risk, while reducing the proportion of late diagnoses of the infection, should improve care for those affected. Surveillance provides indicators that will allow for monitoring the implementation of these recommendations. (R.A)
