"Why Are STDs on the Rise if Americans Are Having Less Sex?"

Atlantic:

On Tuesday, the Centers for Disease Control and Prevention announced that reported cases of three sexually transmitted diseases in the United States had reached an all-time high in 2017. Rates of gonorrhea rose by 67 percent, syphilis by 76 percent, and chlamydia by 21 percent, to a total of almost 2.3 million cases nationwide. According to the CDC, 2017 surpassed 2016 as the year with the most reported STD cases on record—and marked the fourth year in a row that STDs increased steeply in the U.S.

It might seem logical that higher STD rates would go hand in hand with increased sexual activity, but a flurry of recent research indicated American adults are actually having less sex on average than they have in decades.
