Indicator name:
STI: incident cases of curable sexually transmitted infections in 15- 49 year olds
Short name:
Incident cases of curable STIs in adults
Data type:
Number
Indicator Id:
7034
Topic:
Mortality and burden of disease
Rationale:
Gonorrhoea, chlamydia and trichomoniasis are common curable sexually transmitted infections (STIs). Estimates of prevalence and incidence of STIs are important for monitoring STI treatment and prevention programmes and for advocating for funding for STI programming and for the development of new treatments and prevention tools. For gonorrhoea, this is particularly important given the emergence of N. gonorrhoeae resistance to the few remaining antimicrobials recommended for treatment.
Definition:
Incident cases of STIs in individuals 15 to 49 years of age
Disaggregation:
Sex: male, female STI: gonorrhoea, chlamydia, trichomoniasis
Method of estimation:
Incidence estimates in men and women were based on regional prevalence estimates for the 10 geographical regions used in the prevalence calculations. Incidence estimates for all regions, apart from North America, were calculated for women and men using the equation: incidence = prevalence/average duration of infection. The average duration of infection in each estimation region was assumed to depend on the average duration of infection in the absence of treatment for symptomatic and asymptomatic individuals and the probability that symptomatic and asymptomatic individuals are treated appropriately. The same duration parameter values were used in 2016 and 2020. Estimates for North America were based on national estimates produced by the United States Centers for Disease Control and Prevention. Estimates for the 10 regions were then translated into global and WHO regional estimates using UN population estimates of the number of women and men aged 15-49 years of age.
Expected frequency of data dissemination:
