STD cases hit record high in the U.S.
New cases of sexually transmitted diseases in the United States reached an all-time high in 2016, federal health officials reported Tuesday.
There were 1.6 million cases of chlamydia, 470,000 cases of gonorrhea and 28,000 of syphilis reported that year, the U.S. Centers for Disease Control and Prevention announced in its annual report on STDs.
And the diseases are on the rise in a number of groups, including women, infants, and gay and bisexual men.
"Increases in STDs are a clear warning of a growing threat," said Dr. Jonathan Mermin, director of the CDC's National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention.
"STDs are a persistent enemy, growing in number, and outpacing our ability to respond," he said in an agency news release.
Young women account for nearly half of all diagnosed chlamydia infections, but syphilis and gonorrhea are increasingly affecting new groups of people.
Between 2015 and 2016, syphilis rates rose nearly 18 percent. Most cases occurred among men, especially gays and bisexuals. Half of the men in those two groups also had HIV, according to the report.
