Sexually transmitted infections (STIs) of bacterial origin experienced a sharp increase between 2020 and 2022 in mainland France. The proportion of gonorrhea infections jumped by 91% (with 44 cases per 100,000) and that of syphilis increased by 110%.
Syphilis had almost been eradicated since the second half of the 20th century. But it has resurfaced in most Western countries in recent years, notably in the U.S., where infections have reached their highest rate since the 1950s.
