A fatal case of poliomyelitis in a newborn is reported. The case is important as the infant was delivered by cesarean section within a few minutes after maternal death due to acute poliomyelitis. The same immunological strain of poliomyelitis virus was isolated from both infant and mother.
While positive proof is not offered, this case plus a review of the literature offers strong evidence that transplacental transfer of the poliomyelitis virus can occur.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
