The Basics

What is RSV?

Respiratory Syncytial Virus (RSV) is a common virus that infects the nose, throat, and lungs. Most people experience symptoms similar to a cold, but RSV can cause more serious illness in infants, older adults, and people with certain medical conditions.

RSV is one of the leading causes of respiratory infections during the fall and winter months and is a common reason for hospital visits among young children. Vaccination and preventative antibody products can greatly reduce the risk of serious illness requiring hospitalization. Talk to your healthcare provider or local public health unit to learn what RSV prevention options may be available to you and your family.

Who is at higher risk?

Anyone can get RSV, but some people are more likely to become seriously ill:

  • Infants, especially babies under 6 months of age
  • People with chronic medical conditions such as lung disease, asthma, diabetes, heart disease or chronic obstructive pulmonary disease (COPD)
  • Older adults
  • People with weakened immune systems
  • Residents of long-term care and retirement homes or other chronic care facilities

How does it spread?

RSV spreads easily from person to person through:

  • Coughing and sneezing
  • Direct contact with an infected person
  • Touching contaminated surfaces and then touching your eyes, nose, or mouth
  • Close contact such as hugging, kissing, or sharing drinks
A person with RSV can spread the virus before they know they are sick and may remain contagious for several days.
Your Best Protection

Vaccines and preventive products

Vaccines and preventive products are available to help protect people at higher risk of severe RSV illness.

Older adults

Publicly funded RSV vaccines are available for adults aged 75 years and older, as well as high-risk adults aged 60-74. RSV vaccines help reduce the risk of severe illness, hospitalization and complications.

Infants and high-risk children

In Ontario, the RSV prevention program includes two products to help protect infants and high-risk children: monoclonal antibodies available to all infants and high-risk children under 2 years of age and a vaccine given during pregnancy for those delivering during the RSV season.

Talk to your healthcare provider or local public health unit to learn what RSV prevention options may be available to you and your family.
Everyday Habits

Ways to protect yourself

  • Clean your hands often with an alcohol-based hand rub or soap and water
  • Cover coughs and sneezes with a tissue or your sleeve (not your hands)
  • Wear a mask if you have respiratory symptoms or are visiting high-risk individuals
  • Stay home when you are sick
  • Clean and disinfect frequently touched surfaces
  • Stay up to date with recommended vaccines
In the Hospital

Why precautions are necessary

RSV spreads easily from person to person, and people are contagious before and after symptoms appear. Extra precautions (contact and droplet) are used.

Contact and Droplet precautions may include

  • A private room when one is available
  • Wearing a mask, gloves, gowns and eye protection for care activities
  • Limiting patient movement outside the room
  • Hand hygiene before and after contact
The Environment

Cleaning helps

RSV can survive on surfaces for several hours, so cleaning matters. Important measures include:

  • Regular cleaning and disinfection of high-touch surfaces
  • Cleaning and disinfecting shared toys and equipment
  • Frequent cleaning of door handles, railings, and light switches
  • Cleaning and disinfecting medical equipment between uses

Common high-touch surfaces:

Door handles Railings Light switches Shared toys Medical equipment
Proper hand hygiene remains one of the most effective ways to prevent transmission.

Treatment & recovery

There is no specific cure for most RSV infections. Treatment focuses on relieving symptoms and supporting recovery:

  • Drink plenty of fluids
  • Get extra rest
  • Use fever-reducing medications as directed
  • Eat nutritious foods when able
Most people recover within 1 to 2 weeks. Severe infections may need hospital care for oxygen, breathing support, or fluids.

When to seek care

Contact a healthcare provider if you or your child has:

  • High fever that does not improve
  • Difficulty breathing or shortness of breath
  • Bluish lips or skin
  • Signs of dehydration (dry mouth, fewer wet diapers, dizziness)
  • Unusual sleepiness, difficulty waking, or poor feeding in infants
Call emergency services immediately if breathing becomes severely difficult or symptoms rapidly worsen.
Recovering at Home

Looking after yourself at home

Rest and Rehydrate

Drink plenty of fluids, get extra rest, and give your body time to recover. Most people recover fully with supportive care.

Stay Home

Stay home when possible and avoid close contact with others to help prevent the spread of RSV.

Keep It Clean

Cover coughs and sneezes, wash your hands often, and clean frequently touched surfaces every day.

Protect Those at Higher Risk

Avoid exposing infants, older adults, and people with weakened immune systems to coughs, sneezes, and other respiratory secretions.

The Quick Takeaway

RSV in one breath

RSV is a common respiratory virus that spreads easily through close contact and respiratory droplets. While most infections are mild, RSV can cause serious illness in infants, older adults, and vulnerable individuals. Good hand hygiene, vaccination when eligible, staying home when sick, and following infection prevention measures can help protect you and those around you.
