Twenty yearsSTICDC ago, syphilis seemed close to elimination in America. Gonorrhoea rates were also declining. Fast-forward to today and syphilis, gonorrhoea and chlamydia, three of the most common sexually transmitted infections (s), are hitting historic highs (see chart), especially among gay men and certain ethnic-minority groups. In 2021 gonorrhoea reached its highest level since 1991 and syphilis since 1990. Chlamydia’s rates have nearly doubled since 20 years ago. Even babies are being affected. On November 7th the Centres for Disease Control and Prevention () announced that congenital syphilis—passed to babies from infected mothers—increased tenfold from 2012 to 2022.
