Availability of gonorrhoea prevalence reporting globally. Maps represent the availability of prevalence data in general population samples worldwide, including pregnant women, women attending family planning clinics, male military recruits, and work-based health screening programmes and other similar groups. General population estimates were considered ‘national population-based’ or ‘local population-based’ if participants were sampled from a general population sampling frame and some form of random selection was performed. Studies where probability sampling was not conducted, and which may not be generalizable beyond the study, are labelled as ‘non-population based’
