STD rates hit new record high in U.S. after climbing for 5th straight year

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.
