Respiratory Syncytial Virus (RSV)

Overview of RSV

Respiratory Syncytial Virus (RSV) is a virus that causes illness like a bad cold. It spreads easily from person to person, just like a cold.

It can cause breathing difficulties for people of all ages. It can be more serious in babies, older adults, or people with certain health problems.

There are different types of RSV. This means you can get RSV more than once, even in the same year.

Symptoms of RSV infection

In adults and babies:

Cough
Runny or stuffy nose
Sore throat
Earache
Fever

Babies may:

Have low energy
Eat less than usual
Be fussy

Some babies, especially those born early or with health problems, can get serious lung infections like pneumonia or bronchiolitis. Get help if a baby has trouble breathing or is wheezing.

Medicine that protects against RSV

For babies

Nirsevimab (BEYFORTUS®) helps protect babies from RSV after they're born. Nirsevimab is not a vaccine (it's an antibody) and is given:

With a needle
With other routine immunizations

For babies who qualify, Nirsevimab is:

Free
Given in hospital before going home
Available at public health units

An RSV vaccine during pregnancy can help protect your baby after birth. Please contact your health-care provider to learn more. These vaccines may be covered for certain individuals, and are available through pharmacies.

Steps you can take

Individuals who want to learn more about protection from RSV infection should talk with a trusted health-care provider.

Before your baby is born:

Talk to your health-care provider about RSV protection
Ask about vaccines during pregnancy

After your baby is born:

Ask in the hospital if your baby can get RSV protection
If your baby is already home, contact public health or your health-care provider

Important: Babies can get RSV illness soon after leaving the hospital. If your baby qualifies, it's best to get protection before going home. If your baby missed it, they could still get it through public health.
