Indicator name:
STI: incident rate (per 1000) of active syphilis in 15-49 year olds
Short name:
Incident rate of active syphilis in adults
Topic:
Mortality and burden of disease
Rationale:
Syphilis is a common curable sexually transmitted infection (STI). Estimates of prevalence and incidence of syphilis are important for monitoring syphilis treatment and prevention programmes and for advocating for funding for syphilis programming and for the development of new treatments and prevention tools.
Definition:
Incident rate (per 1000) of active syphilis in individuals 15 to 49 years of age. Numerator: Incident cases of syphilis in individuals 15 to 49 years of age Denominator: Number of individuals 15 to 49 years of age
Disaggregation:
Sex: male, female
Method of estimation:
Incidence estimates for all regions, were based on the prevalence estimates for women and men separately using the equation: incidence = prevalence/average duration of infection. The average duration of infection in each country 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 were treated appropriately. The same duration parameter values were used in 2016 and 2020. National estimates 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:
Every 2 to 3 years
