Autism Linked to Fever During Pregnancy
Fever during the second or third trimester of pregnancy is associated with a 40 percent higher risk of having a child with autism, according to researchers from Columbia University.
Results of a study published recently in Molecular Psychiatry suggest that women who develop a fever during pregnancy, especially during the second and third trimesters, are at increased risk for having a child with an autism spectrum disorder. This study supports the theory that autism may be a response to the fever caused by an infection rather than to the viral or bacterial infection itself.
This study was conducted in Norway and involved 95,000 children. In the United States, it’s estimated that about 20 percent of women who are pregnant develop a fever at some point during pregnancy.
