Analysis of the global impact of sexually transmitted infections

Below is a summary of the “Global Burden of Sexually Transmitted Infections” published in the April 2024 issue of dermatology by Sinka et al.

Tackling and controlling the global burden of sexually transmitted infections (STIs) is critical to mitigating associated health impacts. The World Health Organization has updated its global health strategy to prioritize STI prevention and control, highlighting their importance in HIV prevention and sexual and reproductive health initiatives. In a study, researchers sought to quantify and describe the global burden of STIs, using improved data collection methods such as systematic reviews and modeling. The focus was on the main curable STIs—gonorrhea, chlamydia, syphilis, and trichomoniasis—as well as common viral STIs such as human papillomavirus (HPV) and genital herpes. In addition, the study examined the relationship between STIs and HIV and assessed the unequal distribution of these infections worldwide and among specific populations.

Data were collected through systematic reviews and modeling to provide a comprehensive view of the global and regional prevalence and impact of STIs. Despite significant data gaps in many countries, these methods provide valuable insights into the global burden of STIs.

The results demonstrated the substantial prevalence of key curable and viral STIs and highlighted their wide-ranging impact. There was a notable association between STIs and HIV, with a disproportionate burden observed globally and in key populations. Trends in STI rates are influenced by demographic changes, the availability and impact of interventions such as vaccinations, behavioral changes that affect STI transmission, and the impact of international travel on STI spread in an interconnected world.

While data gaps remained, current actions underscored the significant global burden of STIs. Effective control required continued improvements in data collection and targeted interventions, particularly in disproportionately affected populations and regions. The emphasis on STI prevention and control remained a critical component of broader global health strategies, including those on HIV prevention and sexual and reproductive health.
