Women who had the flu or a fever during pregnancy may be at a higher risk of having a child with autism, a new study suggests.
Researchers looked at nearly 91,000 children in Denmark born between 1997 and 2003.
They found mothers who had the flu for a week or longer were twice as likely to have a child diagnosed with autism spectrum disorder before the age of 3.
According to WebMD, there was no evidence of an increase in autism risk among children born to women who had colds, sinus infections, and urinary and genital tract infections during pregnancy.
The study is published in the journal Pediatrics.
