Many Americans lack information about sexually transmitted infections (STIs), a new University of Pennsylvania Annenberg Public Policy Center survey shows. Just over half of survey respondents (54%) know that syphilis can be cured, however, 84% incorrectly believe that a vaccine is available. As many as 30% don’t know the signs and symptoms of syphilis, including sores, swollen lymph nodes, fever, etc., but 77% know that using a condom could protect them. The incorrect responses are somewhat concerning because syphilis cases rose 80% from 2018 to 2022, and many observers believe the trend will continue.
The more you know: When it comes to human immunodeficiency virus (HIV), Americans are comparatively more knowledgeable: 95% know HIV can be spread through unprotected sex; and 90% know it can be spread by sharing needles. Yet, more than half do not realize that there is no vaccine for HIV.
