Measles outbreak and how it affects pregnancy (now over 900 cases reported)
Measles is one of the most contagious viruses we know and also PREVENTABLE! It is airborne and can linger in the air for up to 2 hours after an infected person leaves a room.
In pregnancy, you cannot get the MMR vaccine (measles vaccination). That means vaccination needs to happen before pregnancy.
In pregnancy, measles infection increases the risk of:
• Severe pneumonia
• Hospitalization
• ICU admission
• Preterm birth
• Low birth weight
• Miscarriage
It’s not usually linked to congenital birth defects but when a pregnant patient gets very sick, the unborn baby is affected too.
If a non-immune pregnant patient is exposed, we can give IVIG within 6 days of exposure but that’s damage control. Not prevention.
The safest time to protect a pregnancy from measles
is before conception. Community immunity also matters because it protects those that cannot get vaccinated.
Prevention is always ideal. Vaccination can save lives!
