Sexually Transmitted Infections in the U.S.
Recent data suggests that there are very few cases of chancroids in the U.S. annually. The number of chancroid cases has also been declining globally. Other STIs, such as syphilis had similarly decreased but have recently seen increased rates of infection. On the other hand, rates of chlamydia have steadily increased since the 1980s.
STI Prevention
Some STIs are preventable through vaccination and condoms. A survey from 2022 indicated that around 65 percent of U.S. female teenagers were up to date on their human papillomavirus vaccinations. Condoms, while known for their effectiveness in preventing sexually transmitted infections, are not used as frequently as public health officials would like. For example, a survey from 2021 found that only 27 percent of men in the United States said they used protection every single time they have sex with a new partner.
