A syphilis outbreak in Las Vegas amounted to nearly 700 new cases of the sexually transmitted infection in 2015, health officials reported.
The news comes on the heels of a larger report from the U.S. Centers of Disease Control and Prevention, which last year found that a sexually transmitted disease epidemic is growing in the United States. Nationwide, syphilis cases rose 15 percent between 2013 and 2014, according to the latest CDC data published in February.
The Vegas outbreak, largely driven by cases of syphilis in men, gives Nevada the dubious distinction of the state with the highest rate of syphilis in the West.
Syphilis, which is spread by sexual contact, usually presents in the form of a small sore, later developing into a rash that can cover much of the body, according to the Mayo Clinic. If the disease isn't treated, it can move into an invisible latent stage, which can result in complications such as brain, nerve, eye, heart, blood vessel, liver, bone and joint damage years later.
"It's important for people to understand that you can't look at somebody and tell whether or not they're infected with any of these sexually transmitted infections," Dr. Vanessa Cullins, vice president for external medical affairs at Planned Parenthood Federation of America, previously told HuffPost.
There may be some basis for that assertion. In 2013, a New York University study targeted a possible connection between sexually transmitted diseases and social media hookups, linking Craigslist to a 16 percent in HIV cases between 1999 and 2008.
Tinder and Grindr don't appreciate the negative attention showered on them by public health advocates. In September, Tinder demanded its name be removed from a billboard campaign by the AIDS Healthcare Foundation that depicted male silhouettes with the words "Tinder" and "Grindr" written on them locking lips with silhouettes emblazonment with "chlamydia" and "gonorrhea."
"While Tinder strongly supports such testing, the [b]illboard's statements are not founded upon any scientific evidence," the company wrote in a letter to the AHF. Similarly displeased, Grindr dropped AHF's paid advertising from its site, according to The Guardian.
Sexually active people should use condoms during every sexual encounter to reduce their risk of contracting the disease. Other prevention tips include getting regular STI screenings, limiting sexual partners, and for women, avoiding douching, which decreases the number of good bacteria in the vagina.
