If your baby was born prematurely (35 weeks or less), he or she may be at high risk for severe RSV disease.
A baby that is born prematurely is vulnerable to severe RSV disease because they were born before their respiratory system could fully develop, which makes it harder to fight infection.
If your baby has chronic lung disease (CLD), he or she may be at high risk for severe RSV disease.
CLD is a direct result of injury to the lungs. Some of the causes of lung injury include:
- Being born prematurely – preemie babies do not have fully developed lungs
- Having low amounts of surfactant (a substance in the lungs that helps keep the tiny air sacs open)
- High concentrations of oxygen, which can damage the cells of the lungs
If your baby has congenital heart disease (CHD), he or she may be at high risk for severe RSV disease.
There are many different kinds of heart conditions, such as:
- The heart is not pumping well
- There’s a “hole” between 2 sides of the heart
- Having a heart valve that isn’t working the way it should
- Damage to a chamber or blood vessel, or even being born without a chamber
