Chlamydia trachomatis (CT) infection spreads in Europe and in USA, and tendencies analysis shows an increase in the epidemic since last 10 years. In France, in 2006, a national survey carried out by phone and using a home-based sampling showed that CT prevalence was the highest in young people, with 3.6% for women and 2.4% in men aged 18-24 yo. To face this problem, several countries have developed new strategies, mixing newer technologies and home-based self-sampling test. Inspired by evaluation of those dispositives, the French National Institute of Health Prevention and Education (INPES) decided to experiment the proposition of a free home-based self-sampling to screen this infection via internet in young people 18-24 yo. This study, named Chlamyweb, aims to compare CT screening rate from this intervention with traditional information system and screening centre. Study design was a random control trial, with a 1:2 randomization. Recruitment took place on an Internet information website on sexually transmitted infections, and support by web campaign from September 3 to October 14 2012. Home-based kits were composed by uriswab 3 sponges for men and dry vaginal swabs for women (Copan diagnostics). All samples were analysed by using the fully automated cobas 4800 (Roche diagnostics). Self-sampling was proposed to 5 531 people. Out of them, 47.3% accepted, with a higher rate in women (53.0%). A total of 1616 kits provided [1002 from women (63.8%) and 614 from men (58.8%)] was return to the French National Reference Center for chlamydial infections. The global prevalence was 6.8% (8.3% in women, 4.4% in men). Sexual behaviour and sociodemographic patient's characteristics were collected and their analysis is under investigation. These preliminary results show that Internet testing reaches a population with a high prevalence of CT infection and appears to be acceptable to young people.
