RSV Awareness Week 2026: What Mississauga Families & Seniors Need to Know
RSV Awareness Week runs October 12–18, 2026, right as Ontario's RSV season and its 2026–27 immunization programs get underway. Here is the plain-English version for Mississauga: who's most at risk, how to tell RSV apart from a regular cold, whether your baby or a senior in your family qualifies for the vaccine, and when a walk-in visit is enough versus when to go to the ER.
Quick answer
RSV Awareness Week is October 12–18, 2026 (Government of Canada). RSV usually causes a mild, cold-like illness, but it's the leading cause of bronchiolitis hospitalization in children under two, and it's serious for adults 60+, especially 75+. Starting October 1, 2026, Ontario's RSV programs reopen: eligible infants can get nirsevimab, and the RSV vaccine is free for adults 75+ and for 60–74-year-olds with specific risk factors. Call 911 or go to the ER for breathing trouble, blue or grey lips, or a fever in a baby under 3 months — otherwise, a walk-in visit near Square One is the right call.

What RSV is, and why it gets an Awareness Week
Respiratory syncytial virus (RSV) causes a respiratory illness affecting the lungs and airways, and it's the most common cause of bronchiolitis in infants and toddlers (ontario.ca). It spreads the way most winter viruses do — through droplets from a cough or sneeze, close contact with someone infected, or touching a contaminated surface like a toy, door handle, or countertop (Canadian Paediatric Society).
In Peel Region, RSV is most active from November to April (peelregion.ca). That's why RSV Awareness Week — October 12 to 18, 2026, per Health Canada's calendar of health promotion days — lands right before the season ramps up: a reminder to check your family's eligibility and know the warning signs now, not once RSV is already circulating in Mississauga.
Please note: this guide summarizes public-health sources as of early October 2026. Programs, eligibility, and seasonal timing can change. Confirm current details on ontario.ca or with a health-care provider. This is general information, not medical advice.
Who's most at risk from RSV
RSV usually leads to a mild illness — almost every child catches it at least once before age 2, and for most it's a rough week at home, not a hospital visit (canada.ca). But the Ontario government is clear that some groups face a real risk of severe outcomes (ontario.ca):
- Infants and children under 24 months old
- Children with chronic lung disease or bronchopulmonary dysplasia
- Children with significant congenital heart disease
- Children with severe immunodeficiency, Down syndrome, cystic fibrosis, or a neuromuscular disease
- Older adults, particularly those 60 and older — with the highest risk in adults 75+
Bronchiolitis — RSV's more serious complication, an infection of the small airways leading to the lungs — is one of the most common reasons young children are hospitalized before age two (canada.ca). Knowing which symptoms call for more than rest and fluids is the key skill — covered next.
RSV vs. a regular cold: symptoms to watch
Here's the tricky part: RSV often looks exactly like a cold. Canada's public health agency notes that children with RSV typically have the same symptoms as a common cold — coughing, a runny nose, fever, and a decrease in appetite and energy (canada.ca). In most cases, that's exactly what it stays.
The difference shows up if RSV moves into the lower airways and becomes bronchiolitis, causing wheezing and difficulty breathing. Here is the Canadian Paediatric Society's exact guidance on when to escalate:
| Seek emergency care if your child… | Call a doctor if your child… |
|---|---|
| Has trouble breathing or lips that look blue | Has had a fever for more than 72 hours |
| Is younger than 3 months old and has a fever | Isn't eating, or is vomiting |
| Is “in-drawing” — sucking in of the skin below the ribs or at the neck with each breath | Isn't producing wet diapers |
| Is no longer able to suck or drink | Has a severe cough causing choking or vomiting |
Source: Canadian Paediatric Society. If your child has any of the symptoms on the left, call 911 or go to the nearest emergency room immediately — do not wait for a clinic visit.
In older adults, watch for the same category of red flags: shortness of breath, confusion, or symptoms that are getting worse instead of better after several days. Don't wait it out if breathing becomes difficult.
Ontario's RSV program for infants (2026–27 season)
Ontario's RSV prevention program for infants and high-risk children reopens for the 2026–27 season starting October 1, 2026 (ontario.ca). There are two routes to protection:
If you're currently pregnant: RSVpreF vaccine (Abrysvo)
Funded for pregnant Ontario residents between 28 and 36 weeks gestation who are expected to deliver during RSV season, so protective antibodies pass to the baby before birth.
If your baby is already born: Nirsevimab (Beyfortus)
A single-dose monoclonal antibody given directly to the infant. Available for infants born April 1, 2026 or later who are under 8 months of age at the time of immunization, and for high-risk children under 24 months with qualifying conditions (chronic lung disease, significant congenital heart disease, severe immunodeficiency, Down syndrome, cystic fibrosis, or neuromuscular disease), regardless of birth date.
These are two alternative routes to protection, not sequential steps — which one applies depends on whether you're currently pregnant or your baby is already born. Eligibility depends on your baby's birth date, your RSV vaccination status during pregnancy, and medical history — ask your family doctor, pediatrician, or local public health unit which option applies rather than assuming either way.
The RSV vaccine for adults 60+
Adults don't need a baby in the house to be at risk — RSV hospitalizes older adults every season. Starting with the 2025–26 season, Ontario expanded its funded adult RSV program, and the same eligibility carries into 2026–27 (ontario.ca):
| Age group | Eligibility for the free RSV vaccine |
|---|---|
| 75 and older | Every Ontario resident in this age group, regardless of health status. |
| 60–74 | Only with specific high-risk factors: living in long-term care, a retirement home, or an Elder Care Lodge; in hospital receiving alternate level of care; on hemodialysis or peritoneal dialysis; a solid organ transplant recipient; on home oxygen therapy; experiencing homelessness; or identifying as First Nations, Inuit, or Métis. |
Two RSV vaccines are publicly funded in Ontario: Abrysvo and Arexvy. If you've already had an RSV vaccine in a previous season, you do not need another dose this year (ontario.ca). Ask your doctor or pharmacist whether you qualify — this is a separate vaccine from the flu shot and the COVID-19 booster, not a bundled dose.
Walk-in clinic near me, or the ER?
Peel Public Health's guidance is simple: call 911 for a medical emergency (peelregion.ca). That covers every red-flag breathing sign listed above, for any age.
For everything short of that — a child with cold-like symptoms who's still eating, drinking, and breathing normally, an older adult with a manageable cough, or you're simply unsure whether a visit is needed — a same-day walk-in visit covers it, no appointment required. If you'd rather talk it through first, Health811 (call 811, TTY 1-866-797-0007) offers free health advice 24/7 (peelregion.ca).
Searching "walk-in clinic near me" in Mississauga? Medicare Clinic's walk-in clinic near Square One sees same-day respiratory concerns for all ages, with an on-site lab and pharmacy if tests or a prescription are needed in the same visit. Our family practice is also accepting new patients if you're looking for ongoing, coordinated care for a child with repeat respiratory illness.
RSV and flu season overlap
RSV season runs roughly November through April in Peel Region (peelregion.ca) — almost exactly the same window as flu season, and the two hit the same highest-risk groups: young children and adults 60+. If you're already booking a flu shot this fall, it's worth asking in the same visit whether you or your child also qualify for an RSV vaccine. See our Flu Shot Season 2026 guide for Ontario's flu program details, including eligibility and the vaccine options for seniors.
RSV Awareness Week checklist
- Mark RSV Awareness Week — October 12–18, 2026 — as the week to check your family's eligibility, not the week RSV is already going around.
- If you have a baby under 8 months born on or after April 1, 2026, or a high-risk child under 24 months, ask your doctor about nirsevimab.
- If you're pregnant and due in the fall or winter, ask whether the RSVpreF vaccine at 28–36 weeks applies to you.
- If you or a family member is 60+, confirm your own RSV vaccine eligibility — don't assume it's bundled with the flu shot.
- Save the warning signs above (blue lips, breathing trouble, fever under 3 months) so you know when a walk-in visit isn't enough.
- Keep the clinic's number handy — (905) 848-4844.
Frequently asked questions
When is RSV Awareness Week 2026?
RSV Awareness Week 2026 runs from October 12 to 18, according to Health Canada's calendar of health promotion days. It falls just as Ontario's RSV season and the province's RSV immunization programs are getting underway for the year.
Who is most at risk from RSV?
Infants and children under 24 months old are at highest risk, especially those with chronic lung disease, congenital heart disease, severe immunodeficiency, Down syndrome, cystic fibrosis, or a neuromuscular disease. Older adults, particularly those 60 and older and especially 75 and older, are also at higher risk of severe illness. Source: ontario.ca.
How can I tell RSV apart from a regular cold?
According to the Canadian Paediatric Society, children with RSV typically have the same symptoms as a common cold: cough, runny nose, fever, and reduced appetite and energy. The difference shows up if it progresses to bronchiolitis, with wheezing or difficulty breathing. Seek emergency care if a child has trouble breathing, blue-looking lips, is under 3 months old with a fever, is in-drawing (sucking in skin below the ribs or at the neck with each breath), or can no longer suck or drink. Source: Canadian Paediatric Society.
Is there an RSV vaccine for infants in Ontario?
Yes. Ontario's RSV prevention program reopens for the 2026–27 season on October 1, 2026. Nirsevimab (Beyfortus) is available for infants born April 1, 2026 or later who are under 8 months old at the time of immunization, and for high-risk children under 24 months with qualifying medical conditions. A maternal RSV vaccine (Abrysvo) is also funded for pregnant residents between 28 and 36 weeks gestation expected to deliver during RSV season. Source: ontario.ca.
Is the RSV vaccine free for seniors in Ontario?
Adults 75 and older receive the RSV vaccine free regardless of health status. Adults 60 to 74 qualify for a free dose only if they meet specific high-risk criteria, such as living in a long-term care or retirement home, being on dialysis, having a solid organ transplant, using home oxygen therapy, experiencing homelessness, or identifying as First Nations, Inuit, or Métis. If you've had an RSV vaccine in a previous season, you do not need another dose. Source: ontario.ca.
When should I go to the ER instead of a walk-in clinic for RSV symptoms?
Call 911 or go to the ER for a medical emergency: trouble breathing, blue or grey-looking lips, a fever in a baby under 3 months, in-drawing of the skin around the ribs or neck with each breath, or an infant who can no longer suck or drink. For milder, cold-like symptoms, a same-day walk-in visit is appropriate, or call Health811 (811) for advice. Source: peelregion.ca, Canadian Paediatric Society.
