Influenza (the flu), COVID-19, and respiratory syncytial virus (RSV) are common, highly contagious illnesses that affect the airways and lungs.
These viruses typically circulate in the highest numbers during the annual fall respiratory illness season, which, in Ontario, runs from November to April.
Respiratory illnesses spread when an infected person coughs, sneezes, or has face-to-face contact with someone else. They can also spread when someone touches a surface contaminated by a respiratory virus and then touches their eyes, nose, or mouth.
In most cases, the flu, COVID-19, and RSV can be managed at home. However, these viruses can cause serious illness. Those most at risk of developing a serious illness include babies and young children, seniors over age 65, and people with underlying medical conditions.
Staying up to date on recommended vaccines is a safe and effective way to protect against serious complications from respiratory viruses.
Flu symptoms may vary from person to person. Some people get mildly ill. Others get very sick.

Flu symptoms can range from mild to severe and typically last 7-10 days.
Common symptoms include:
Some people may also experience diarrhea or vomiting.
To help manage symptoms at home, get extra rest, stay hydrated (water is best), and consider over-the-counter medications.
To relieve body aches and headache or to lower fever, you can try acetaminophen or ibuprofen. You can try a nasal or oral decongestant for a stuffy nose, a cough suppressant for a dry, hacking cough, and throat lozenges to soothe a sore throat.
Be safe with medicines and always follow instructions on the label. Cough and cold medicines may not be safe for young children or for people with certain health problems. Consult with a primary care provider or pharmacist if you have any questions or concerns about the best over-the-counter medications to try.
If you or someone you’re caring for develops severe symptoms, such as shortness of breath or chest pain, call 911 or go to the nearest emergency department.
Most people with the flu can recover at home, but some symptoms mean you need help right away.
You should go to an emergency department if you are having trouble breathing or start wheezing, if you become very pale or your lips turn white or blue, become very sleepy/difficult to wake, get a fever that stays high and won’t go down, experience repeated vomiting and are unable to keep any liquids down, develop signs of dehydration with dry mouth or no urination or if you get vomiting or diarrhea with a large amount of blood in it.
While anyone can get sick from the flu, some people are more likely to develop serious illness. This includes babies and young children, seniors, people in long-term care homes, people who are pregnant, and people with underlying health conditions.
The flu can worsen chronic conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), or congestive heart failure.
If you are immunocompromised or at high risk of severe complications from the flu, you should speak with a healthcare provider or participating pharmacist as testing and treatment options may be available.
The flu shot is an effective, safe way to protect against severe illness from the flu. It is recommended for anyone aged six months and older and is available seasonally at participating pharmacies and through primary care offices.
You can also help to prevent the spread of the flu by staying home when sick, washing your hands often for at least 15 seconds or using hand sanitizer, covering your mouth when you cough or sneeze, regularly cleaning high-touch surfaces, and wearing a tight-fitting, well-constructed mask if visiting a healthcare facility.
Commonly reported symptoms of COVID-19 include:
You should go to an emergency department if you have:
You may be at risk of more severe disease or outcomes from COVID-19 if you:
Evidence shows that the COVID-19 vaccines used in Canada are very effective at preventing severe illness, hospitalization, and death from COVID-19.

You can also help to prevent the spread of COVID-19 by staying home when sick, washing your hands often for at least 15 seconds or using hand sanitizer, covering your mouth when you cough or sneeze, regularly cleaning high-touch surfaces, and wearing a tight-fitting, well-constructed mask if visiting a healthcare facility.
RSV usually causes a mild illness. However, some groups, including infants and older adults, are at increased risk for severe outcomes.
RSV is, for example, the most common cause of bronchiolitis, a common chest infection that affects infants and toddlers.
Signs and symptoms of RSV range from mild cold symptoms to severe respiratory distress and can include:
Symptoms generally begin four to six days after exposure to the virus. An ill person can spread the virus for up to eight days and sometimes longer. It can take a week or two to feel better.
You can use acetaminophen or ibuprofen for fever and pain. However, do not give ibuprofen to babies under six months of age without speaking with a healthcare provider. Never give aspirin to children.
Offer plenty of fluids to prevent dehydration. If your baby is having trouble drinking, try to clear nasal congestion with a bulb syringe or saline nose drops.
Consult your healthcare provider before giving your child non-prescription cold medicines.
You should go to an emergency department if you or someone you’re caring for has trouble breathing, pale skin, lips that look white or blue, asthma or wheezing, or has any of the following symptoms:
Certain health conditions may place you at a higher risk, such as heart or lung disease.
Immunization is available to eligible individuals to help prevent serious outcomes, such as hospitalization, caused by the virus.
