Sexually transmitted infections and sexual health

Sexually transmitted infections (STIs), which sometimes show no symptoms, can lead to infertility and other significant health challenges. Every day, there are more than 1 million new cases of curable STIs among people aged 15 to 49, according to the World Health Organization1. This amounts to more than 376 million new cases annually of four infections -- chlamydia, gonorrhoea, trichomoniasis, and syphilis. These STIs2 have a profound impact on the health of adults and children worldwide; yet, they can be treated with available medicines. In addition to infertility, they can lead to neurological and cardiovascular disease, ectopic pregnancy, stillbirths and increased risk of HIV.

Safe sexual practices, sex education and timely testing and treatment are crucial for reducing the burden of STIs globally. Diagnostic testing is3 often the first line of defense, and the impact of quality diagnostics and innovative testing approaches has transformed previously life-altering STIs into manageable conditions.
