Seizures

Children are at a higher risk for developing seizures with the flu virus, and in addition to suffering seizures as a result of the virus, they can also suffer from febrile seizures, characterized by convulsions or rapid twitching or jerking motions. These seizures are common in children whose fevers rise above 102 degrees Fahrenheit or who experience rapid temperature increases from fever. While scary, febrile seizures typically do not cause permanent damage.

A 2010 study from the University of Utah found that the swine flu was more likely to cause neurological complications in children than the seasonal flu, but those in high-risk categories should be aware of this risk.

Premature Labor and Delivery

For pregnant women who debate the merits of getting an annual seasonal flu shot, studies show that pregnant women who get the flu are at a risk of developing other complications that may be debilitating or deadly for their unborn children. Infections like flu are linked to low birth weight and higher rates of preterm birth. A 2012 study found that mothers who contracted the flu during their pregnancies were more likely to give birth to children with neural tube defects, including defects of the brain and spine.

And it’s not just our unborn children who are in a high-risk category during flu season. Studies have shown that pregnant women who catch the flu are at a risk for serious flu-related complications, including pneumonia or death.
