Every day, there are more than 1 million new cases of curable sexually transmitted infections (STIs) among people aged 15-49 years, according to data released today by the World Health Organization. This amounts to more than 376 million new cases annually of four infections - chlamydia, gonorrhoea, trichomoniasis, and syphilis.
Published online by the Bulletin of the World Health Organization, the research shows that among men and women aged 15–49 years, there were 127 million new cases of chlamydia in 2016, 87 million of gonorrhoea, 6.3 million of syphilis and 156 million of trichomoniasis.
These STIs have a profound impact on the health of adults and children worldwide. If untreated, they can lead to serious and chronic health effects that include neurological and cardiovascular disease, infertility, ectopic pregnancy, stillbirths, and increased risk of HIV. They are also associated with significant levels of stigma and domestic violence.
Syphilis alone caused an estimated 200 000 stillbirths and newborn deaths in 2016, making it one of the leading causes of baby loss globally.
WHO notes that STIs are preventable through safe sexual practices, including correct and consistent condom use and sexual health education.
