Protecting Your Child from Respiratory Syncytial Virus (RSV)

By Humber River Health

As a parent, nothing is more important than your child’s health. One virus that has garnered attention, particularly during the fall and winter months, is Respiratory Syncytial Virus (RSV). This virus is a major cause of respiratory illness in infants and young children and is a leading cause for infant hospitalization here at Humber River Health, and across the province. Understanding RSV, its symptoms, and preventive measures can help keep your little one safe.

What is RSV?

RSV primarily affects the airways and lungs, often manifesting as cold-like symptoms. For most healthy children, RSV may result in mild illness; however, it poses a greater risk for premature babies and babies under two years old. Because they are still developing their immune system and respiratory systems, these babies can become very ill if infected.

How RSV Spreads

RSV spreads easily through:

  • Direct contact with infected individuals or surfaces.
  • Airborne transmission when an infected person coughs or sneezes.

The virus is most active from late fall to early spring, making it essential to stay vigilant during these months.

Recognizing the Symptoms of RSV

Common symptoms of RSV include:

  • Runny nose
  • Cough
  • Fever
  • Wheezing
  • Irritability
  • Low energy or unusual tiredness
  • Decreased appetite or fluid intake

If you notice any of these symptoms in your child, especially if they have trouble breathing, signs of dehydration, or if their condition worsens, seek medical attention promptly.

Preventive Measures

Preventing RSV involves both good hygiene practices and available medical interventions. Here are some key strategies to protect your child:

  1. Good Hygiene
  • Wash hands frequently.
  • Cough or sneeze into your arm.
  • Avoid smoking near your child.
  • Clean and disinfect surfaces regularly.
  1. Breastfeeding
  • If you’re able to, breastfeeding can provide additional antibodies to your baby.
  1. Stay Home When Sick
  • Limit exposure by staying home when you’re unwell and avoid close contact with sick individuals.

What’s New in RSV Prevention

Starting November 1, 2024, there are two main preventive options available for young children:

  1. Preventive Antibody Medication (Beyfortus™)
  • What it is: Beyfortus™ acts like natural antibodies to help eliminate RSV.
  • How it’s administered: It’s given as a one-time injection in the thigh muscle, offering protection for up to six months.
  • Eligibility: This medication is recommended for babies born in 2024 before or during the RSV season and children under two years old who are at high risk for severe RSV. For more information on Beyfortus, please review this brochure.
  1. Vaccine for Pregnant Persons (Abrysvo™)
  • What it is: Abrysvo™ is administered to pregnant individuals to protect their babies from RSV.
  • Timing: It’s given between 32 and 36 weeks of pregnancy.
  • How it works: This vaccine helps the pregnant person’s immune system create antibodies that are passed to the baby, offering protection for the first six months of life.

How to Access Immunization

If your baby was born in 2024, you can choose to immunize them against RSV during your hospital stay. Your healthcare team will discuss this option with you. If you wish to book an appointment at Humber River Health’s RSV clinic for immunization, please call 416-242-1000 ext. 21400.
