A new study suggests mothers who had fevers during pregnancy were more than twice as likely to have a child with autism or a developmental delay.
The research comes from a team of University of California researchers. They studied 1,100 children ages 2 to 5 in California.
They found mothers who controlled their temperatures with medication or who didn't have fevers at all had a much lower risk of having a child with a developmental delay.
This is believed to be the first study of its kind.
