Global STI infection map
Explore STI prevalence, outbreak trends, and epidemiological data across the world. Click any highlighted country to see its top five infections and current alert level.
Educational data only. Figures are drawn from WHO, CDC, ECDC, and national health authority reports and are approximate. They are intended for awareness and education — not clinical decision-making. Surveillance capacity varies significantly between countries.

How to read this map
Alert levels
Countries are colour-coded from low concern (pale teal) to critical (red) based on a composite of reported incidence rates, outbreak status, and antibiotic resistance threats from authoritative surveillance sources.
Top 5 infections
Clicking a country shows the five most common or clinically significant STIs, the most recent reported rate or diagnostic count, and a trend indicator showing whether cases are rising, stable, or falling.
Trend arrows
A rising arrow indicates an upward trend in the most recent annual data. A falling arrow indicates progress. Stable indicates no significant directional change. Trends refer to the direction of reported cases, not to severity.
Data currency
Most figures are from 2022–2023 surveillance reports. Some countries report with a 12–18 month lag. Countries without colour have insufficient publicly available surveillance data to categorise reliably.
Reporting gaps
Many low- and middle-income countries have significant under-reporting. An absence of data does not mean an absence of infections — in many cases it reflects surveillance infrastructure gaps.
Sources
Data is drawn from WHO Global Health Observatory, CDC, ECDC, UKHSA, AIHW, PHAC, NIID Japan, and individual national health ministry reports. Each country panel cites its primary source.
