Fever During Pregnancy May Increase Autism Odds

Expectant mothers who have a fever during pregnancy are significantly more likely to have a child with autism, new research suggests.
The odds of a child developing autism increased 34 percent in women who came down with a fever at any time during pregnancy. The risk was greatest during the second trimester when a 40 percent bump was observed.
Researchers looked at data on 95,754 kids born in Norway between 1999 and 2009. About 16 percent of mothers reported having a fever at some point during pregnancy and nearly 600 of the children were ultimately diagnosed with autism.
The risk for autism appeared to increase with the frequency of fevers. Women who experienced fevers three or more times after their 12th week of pregnancy had a 300 percent higher chance of having a child with autism, the study found.
