Respiratory Syncytial Virus (RSV) is a common respiratory infection that can affect people of all ages. For many people, it causes mild, cold-like symptoms. However, RSV can sometimes lead to more serious illness in infants, young children, older adults, and people with certain ongoing health conditions.

RSV Awareness is an opportunity to remind families and caregivers about the importance of recognising symptoms, practicing everyday prevention habits, and understanding who may need additional protection.

For families in Mississauga, knowing the basics about RSV can help them make informed decisions about their health and understand when to seek medical advice. At BritCare Medical Clinic, patients can discuss respiratory health concerns as part of their family healthcare and ask about appropriate next steps.

What Is RSV?

RSV stands for Respiratory Syncytial Virus. It is a common virus that affects the respiratory system, including the nose, throat, and lungs. Most people experience symptoms similar to a common cold and recover without serious problems. However, some people may develop more significant breathing difficulties or other complications. RSV commonly circulates during the fall and winter months in Ontario, although the timing and level of activity can vary each year.

Who Is More Vulnerable to RSV?

RSV can affect anyone, but certain age groups may have a greater risk of developing serious illness.

Infants and Young Children

Babies, particularly those in their first months of life, need extra attention during respiratory virus season. Their developing respiratory systems can make it harder for them to manage certain infections. Parents should watch for changes in feeding, breathing, and general behaviour. Premature infants and children with certain health conditions may need additional protection.

Older Adults

RSV is also an important health concern for seniors. Older adults, particularly those aged 75 and older and some adults aged 60 to 74 with specific health risks, may have a greater chance of developing severe illness. Older adults living with ongoing heart or lung conditions or weakened immune systems should discuss respiratory infection prevention with their healthcare provider.

People With Ongoing Health Conditions

People with certain existing health conditions may need additional attention during RSV season. A healthcare professional can help them understand their individual risk and discuss suitable preventive options.

Common RSV Symptoms to Watch For

RSV symptoms can resemble those of a common cold. They may develop gradually and vary from person to person. Common symptoms include:
  • Runny or blocked nose.
  • Coughing.
  • Sneezing.
  • Fever.
  • Reduced appetite.
  • Tiredness.
  • Wheezing in some cases.
In babies, symptoms may be less obvious. Parents might notice that their child is feeding less than usual, seems unusually irritable, or has changes in breathing. These symptoms do not automatically mean someone has RSV. Other respiratory infections can cause similar signs. A healthcare professional can assess symptoms and recommend appropriate next steps.

How Does RSV Spread?

RSV can spread through close contact with someone who is infected, as well as through respiratory droplets and contaminated hands or surfaces. For example, the virus may spread when:
  • An infected person coughs or sneezes nearby.
  • Someone has close contact with a person who has RSV.
  • A person touches a contaminated surface and then touches their eyes, nose, or mouth.
RSV can spread easily among family members, particularly when children attend school or childcare and return home with respiratory symptoms. Understanding how the infection spreads can help families take simple steps to protect one another.

How Can Mississauga Families Help Prevent RSV?

Everyday hygiene habits can help reduce the spread of RSV and other respiratory infections.

Practise Regular Handwashing

Wash hands with soap and water, especially before preparing food, eating, or handling a baby. Encourage children to wash their hands after playing and when they return home.

Cover Coughs and Sneezes

Use a tissue or the inside of the elbow when coughing or sneezing. Dispose of used tissues and wash hands afterwards.

Clean Frequently Touched Surfaces

Regularly clean commonly touched household surfaces, toys, tables, and door handles, particularly when someone at home is unwell.

Avoid Close Contact When Sick

If a family member has cold-like symptoms, limit close contact with infants and older adults where possible. Avoid kissing babies when you are unwell, and do not share cups or utensils.

Stay Home When Feeling Unwell

When possible, avoid school, childcare, work, and social gatherings while experiencing symptoms of a contagious respiratory illness. This can help reduce exposure for people who may be more vulnerable.

What Should Families Know About RSV Prevention in Ontario?

Ontario may offer RSV prevention programmes for certain eligible groups. Available options and eligibility requirements can change over time. Patients should refer to current provincial guidance or speak with a healthcare professional for the most up-to-date information. The most appropriate option depends on individual circumstances and current provincial recommendations. It is important to understand that RSV preventive antibody products and RSV vaccines are different. They are not interchangeable, and the appropriate option depends on the individual's circumstances. Programme eligibility, availability, and timing can change. Families should check the latest Ontario guidance or speak with a healthcare professional or local public health unit for current information. Not everyone will qualify for the same prevention option. A healthcare professional can help explain which options may be appropriate based on individual needs and current recommendations.

When Should Parents Seek Medical Advice?

Parents and caregivers should pay attention to changes in a child's breathing, feeding, and general behaviour. Consider contacting a healthcare professional if a child has:
  • A persistent or worsening cough.
  • Fever or ongoing cold-like symptoms.
  • Reduced feeding or difficulty drinking.
  • Fewer wet diapers than usual.
  • Unusual tiredness or irritability.
  • Wheezing or changes in breathing.
Seek emergency medical care immediately if a baby or child has severe difficulty breathing, pauses in breathing, blue or grey lips or skin, or is difficult to wake. Parents should seek medical advice whenever they are concerned about a young infant, even if symptoms appear mild.

Why Should Seniors Pay Attention to RSV?

Older adults may sometimes mistake RSV symptoms for an ordinary cold. However, respiratory infections can be more challenging for people with certain existing health conditions. Seniors and their caregivers should watch for:
  • A cough that persists or becomes worse.
  • Fever or unusual tiredness.
  • Changes in breathing.
  • Reduced appetite.
  • Difficulty staying hydrated.
  • A noticeable change in everyday activity.
Older adults who develop new or worsening respiratory symptoms should contact a healthcare professional for guidance. Severe or rapidly worsening symptoms require emergency medical attention rather than a routine clinic appointment.

How Can a Family Doctor Help During RSV Season?

A family doctor can help patients discuss respiratory health concerns and understand appropriate preventive care. Depending on the patient's needs, an appointment may include:
  • Assessing respiratory symptoms.
  • Reviewing relevant medical history and ongoing health conditions.
  • Discussing respiratory health concerns and current preventive care recommendations
  • Providing guidance about when further medical assessment may be needed.
  • Recommending appropriate follow-up.


For families looking for a family doctor in Mississauga, ongoing primary healthcare can provide an opportunity to discuss health concerns for children, adults, and older family members.

A walk-in clinic in Mississauga may also provide prompt medical assessment for non-emergency respiratory concerns when a regular family doctor is unavailable. Clinic services and availability can vary.

At BritCare Medical Clinic, family medicine and geriatric care support patients with healthcare needs at different stages of life. Patients can discuss relevant concerns with their healthcare provider and receive guidance on appropriate next steps.

Helping Mississauga Families Stay Informed About RSV

RSV is a common respiratory infection, but it can affect people differently depending on their age and health. While many RSV infections cause mild, cold-like symptoms, infants, young children, older adults, and people with certain ongoing health conditions may need additional attention.

Mississauga families can help reduce the spread of RSV through good hygiene, awareness of common symptoms, and appropriate preventive care. Parents and caregivers should also understand when to seek medical advice and when symptoms require emergency attention.

If you have concerns about RSV symptoms or prevention for yourself or an older family member, speak with a qualified healthcare professional. Understanding the available options can help you make informed decisions about your family's health.
