§ Estimate of the number of active syphilis infections [5]
|| Estimate based on the average transmission risk of mother to child (in the absence of treatment and/or vaccination) and the estimate of the number of new diagnoses (HIV/HBV) or active infection (syphilis) (based on women with a confirmed result)
