Instances of gonorrhea, chlamydia, and syphilis have risen among sexually active Americans for the fifth year in a row, according to a new report from the Centers of Disease Control and Prevention. Researchers say the combined total of all the infections hit 2.4 million this year, a new record.
This comes after the rates of those diseases was in decline — syphilis, for instance, had been decreasing since the early 1940s. In this recent surge, adolescents and young adults were the highest-affected of the studied demographics.
These diseases can cause conditions such as infertility. Syphilis can also be passed on to infants, sometimes fatally so.
