See 2016 WHO report, the spread continues
The spread of sexually transmitted infections continues to rise in America. More than 17,375 cases of primary and secondary syphilis were detected in the United states in 2013. This corresponds to an incidence of 5.5 cases per 10,000 persons, a 10% increase with respect to 2012. Ninety-one percent of cases occurred in men, 75% of which were in homosexual men.
“STDs are a significant health challenge facing the United States. CDC estimates that nearly 20 million new sexually transmitted infections occur every year in this country, half among young people ages 15–24, accounting for almost
$16 billion in health care costs. Each of these infections is a potential threat to an individual’s immediate and long-term health and well-being. In addition to increasing a person’s risk for acquiring and transmitting HIV infection, STDs can lead to severe reproductive health complications, such as infertility and ectopic pregnancy.”
