Number of adults reported with syphilis (primary/secondary and latent/unknown) in the past 12 months
Export Indicator
Progress in reducing unprotected sex in the general population.
Infection with an acute bacterial STI such as primary/secondary syphilis is a marker of unprotected sexual intercourse and facilitates HIV transmission and acquisition. Therefore, surveillance for primary/secondary syphilis contributes to second-generation HIV surveillance through providing early warning of the epidemic potential of HIV from sexual transmission and on-going high-risk sexual activity that may need more aggressive programme interventions to reduce risk. Furthermore, untreated syphilis causes stillbirths and neonatal disease, and can progress to debilitating or fatal outcomes in adults.

Routine health information systems
Disaggregations: Sex, Primary/secondary vs. latent/unknown: Total, Total Female, Total Male, Female primary/secondary, Male primary/secondary

Gender: Male, Female
Although WHO has provided a global case definition, actual case definition may vary between and within countries. Furthermore, diagnostic capacity may vary between and within countries. Although underreporting of this indicator may occur, in the absence of changes in case definition or major changes in screening practices, these data can generally be used for following trends over time within a country.
Additional considerations: It is important that countries when reporting on syphilis communicate on the extent to which the data are felt to be representative of the national population.
Data utilization: Look at trends in comparable groups over time.
