Re: Investigating the pregnant woman exposed to a child with a rash
I partially agree with Dr. Peter J Flegg. Humans are the sole natural host of syphilis. The disease is most common in Sub-Saharan Africa, South and Southeast Asia, and South America though it has declined in developed countries including USA1,2. The diagnosis of syphilis beyond early infancy (among children) raises concerns for possible child sexual abuse, although progression of congenital syphilis may account for some cases2. At this juncture , I shall highlight (as stated in my previous response as well) that the pregnant woman can acquire the infection from other age groups too and not necessarily from a child.
