Who's At Risk
Approximately 50% of full-term newborns develop erythema toxicum shortly after birth, most commonly seen on the second day of life. Preterm infants are less commonly affected; however, they may develop erythema toxicum at a week of life. It is also uncommon in infants who weight less than 5.5 pounds at birth. The rash does not appear to be seen more often in any particular sex or race.
