Children whose mothers said they had a fever lasting more than a week during pregnancy had triple the risk of autism. … They also found that women who took certain antibiotics were more likely to have a child with autism, but it’s not clear if it’s the drug itself, or if women who took antibiotics were perhaps sicker than the other women. ... “Animal studies suggest that when the mother’s immune system is triggered during pregnancy, such as when she is fighting off an infection… that immune response might affect a child’s developing brain,” Boyle said. It’s also not clear if there is something special about the influenza virus. “Misreporting of influenza is likely to be considerable; any episode of fever may be mistaken for influenza, and not all women infected with influenza virus might have been aware of this,” the researchers wrote.
