Respiratory syncytial virus (RSV)

Respiratory syncytial virus (RSV) is respiratory illness that affects the lungs and airways. RSV can be severe in infants, young children and older adults.

RSV spreads from person to person through coughing or sneezing, or by touching surfaces that are contaminated by the virus.

To protect yourself from RSV you can:

  • Frequently wash your hands with soap and running water, or use an alcohol-based hand rub
  • Frequently clean and disinfect common surfaces and items
  • Get an RSV vaccine if you are eligible
 Symptoms
RSV symptoms usually happen within two to eight days after getting infected, and usually include:
  • Runny nose
  • Decrease in appetite and energy
  • Coughing
  • Sneezing
  • Fever
  • Wheezing

Very young infants may only experience irritability, decreased activity, decreased appetite or feeding and breathing problems.

Information for parents on how to manage their child’s symptoms and when to seek medical attention can be found on the Ministry of Health’s RSV webpage. 
 Complications

Some people can develop a severe form of RSV which may result in pneumonia or, in infants and children, bronchiolitis.

These illnesses can be serious and may require a visit to a health care provide or to the emergency department.
