Surveillance of sexually transmitted diseases in France is based on voluntary networks of laboratories and clinicians. Despite the importance of incidence data in improving knowledge about the national context and in international comparisons, such data were not previously available. During nationwide quality control of laboratories, mandatory for all laboratories, we conducted a survey in June 2013 to estimate the incidence rates of gonococcal and chlamydial infections for 2012 and to estimate the proportion of diagnoses performed (coverage) by the country's two laboratory-based sentinel networks for these diseases. Estimated incidence rates for 2012 were 39 per 100,000 persons aged 15 to 59 years for gonorrhoea and 257 per 100,000 persons aged 15 to 49 years for chlamydia. These rates were consistent with the average levels for a group of other Western countries. However, different estimates between countries may reflect disparate sources of surveillance data and diverse screening strategies. Better comparability between countries requires harmonising data sources and the presentation of results. Estimated coverage rates of the gonococcal and chlamydial infection surveillance networks in France in 2012 were 23% and 18%, respectively, with substantial regional variations. These variations justify improving the representativeness of these networks by adding laboratories in insufficiently covered areas.
