350–500. >500. Syphilis is a bacterial infection transmitted by sexual contact [2] and is believed to have infected 12 million people in 1999 with greater than 90% of cases in the developing world. [3] It affects between 700,000 and 1.6 million pregnancies a year, resulting in spontaneous abortions, stillbirths, and congenital syphilis. [4]

To understand health at the community level, scientists and health experts look ...
