Asthma & Pneumonia


Asthma is a condition in which the patients airways narrow and swell, and produce extra mucus. It makes the the patients breathing difficult and triggers coughing, a whistling sound (often referred to as wheezing) when they breathe in and out, and results in shortness of breath.  

In 2020, according to Statista, 2.8 million Canadians were diagnosed with Asthma. This represents 7.4% of the Canadian population (38.1million) in 2020. 

According to the Asthma Canada Asthma Attack Toolkit Asthma is the result the muscles surrounding the airways tighten and your airways become too narrow for you to breathe effectively.

An attack can happen suddenly if your asthma is not under control and you are exposed to one of your triggers. Or, it can build up slowly over hours, days or even weeks before triggering.

When an Asthma Attack occurs, most persons who have previously been diagnosed with Asthma, will use what is referred to as a Rescue Inhaler to alleviate the attack. Rescue Inhalers have to be prescribed to the patient by a physician. 

For some patients Asthma is a nuisance, for other it can pose a serious health situation. There is currently no known cure for Asthma.

Asthma Canada Breathe Easy Diagnosis: Do you have Asthma: Get the Answers guide has been developed to provide Canadians with current and accurate information about Asthma and Asthma management. 



Pneumonia is an infection of one or both lungs. It can be caused by bacteria, viruses (Influenza), or fungi. It is serious life threatening illness where the air sacs of the lung fill with pus and other liquid.

It is considers to be one of leading cause of Pneumonia in Canada.  According to Statista Pneumonia is the 8th leading cause of death in Canada
