The Flu and Pregnancy

by: Angie Warner WHNP

Influenza (Flu) is a virus that is spread from person to person through direct contact and through the air (by cough, sneeze or talking).  Influenza is not the same as the stomach flu.  The Flu is a respiratory illness that can be very serious, especially in children, elderly and pregnant women.  Although it is spread from person to person, the molecule is too large to cross the placenta and spread to an unborn baby.

However, that being said, just because your unborn baby cannot contract the flu during pregnancy does not mean there are not health risks to the baby if you get the flu.  Women who have the flu during pregnancy are more likely to have preterm birth (<37 weeks gestation) which can lead to health concerns for the baby depending on the gestational age.   The flu can lead to pneumonia and can also significantly reduce the levels of oxygenation to your vital organs and to your baby.  The Flu can also lead to high fevers that may cause some birth defects in your baby in early pregnancy.

All pregnant women are encouraged to get the flu shot.  It is recommended that they have preservative-free vaccine as early in pregnancy as possible or even prior to pregnancy.   For women who are already in their second or third trimester it is still recommended to get your flu shot to not only help protect you and your unborn baby, but the antibodies will be passed from mom to baby so that if he/she is born during flu season the baby will actually have some protection.   It is not recommended for babies to receive the flu shot until 6 months of age.

If you are planning to become pregnant or are already we encourage you to get your flu shot.  If you are pregnant and feel that you may have the flu, please call the office for further advice.

We hope you have a healthy and happy holiday season.
