This Week in PLoS Medicine: Gastroenteritis economics; Prenatal treatment of toxoplasmosis; Genomic medicine & public health

Three new articles were published this week in PLoS Medicine:

Stephen Freedman and colleagues performed a cost analysis of the routine administration of ondansetron in both the United States and Canada and show that its routine administration to eligible children in such settings could provide substantial benefit.

An observational study by Ruth Gilbert and colleagues finds that prenatal treatment of congenital toxoplasmosis could substantially reduce the proportion of infected fetuses that develop serious neurological sequelae.

Wayne Hall and colleagues discuss the limitations of genomic risk prediction for population-level preventive health care.
