Hypothesis
What is the prevalence of chlamydia, gonorrhoea, and trichomoniasis among male and female populations in sub-Saharan Africa from 2000 to 2024?
Conclusion
Chlamydia prevalence is increasing in sub-Saharan Africa, with significant geographic variation in STI burden.
Supporting Evidence
- In 2020, chlamydia prevalence was 6.6% among females and 4.7% among males.
- Gonorrhoea prevalence was 2.4% among females and 1.7% among males.
- Trichomoniasis prevalence was 6.8% among females and 1.7% among males.
- Chlamydia prevalence increased by 34.5% from 2010 to 2020 in SSA.
Takeaway
This study looked at how common certain STIs are in Africa and found that chlamydia is becoming more common, especially in some areas.
Methodology
The study used a systematic review and meta-regression analysis of STI prevalence data from various databases.
Potential Biases

Limitations
The study is limited by the availability of data and may not represent all regions equally.
Participant Demographics
The study included general populations aged 15-49 from 28 countries in sub-Saharan Africa.
