Key points

HIV

• In 2017, the annual rate of new HIV diagnoses was estimated at 58 per million people in the Grand Est region, or 316 new cases. Since 2003, this rate has changed very little.

• New HIV diagnoses most frequently occur among men who have sex with men. Sexual contact remains the most common mode of transmission regardless of sexual orientation.

• In 2017, the proportion of positive test results was 1.3 per 1,000 tests performed.

Other sexually transmitted infections (chlamydia, gonorrhea, and syphilis)

• In 2017, 1,545 cases of Chlamydia infection and 321 cases of gonorrhea (down from 2016) were reported by the surveillance laboratories (Renachla and Renago) in the region.

• In 2017, 92 cases of recent syphilis were reported by the RésIST network, a number also down from 2016 (111 cases).

• While cases of syphilis and gonorrhea primarily affect men—gay or bisexual—with a median age between 30 and 35 years, cases of chlamydia primarily affect women (67%) and young people (median age of 24 years). Co-infection with HIV is found in 54% of syphilis cases.

Prevention

• Regardless of sexual practices or sexual orientation, condom use remains low and appears to be declining for certain STIs.

• Data on pre-exposure prophylaxis (PrEP) show an increase in the number of people who have started or renewed PrEP.
