Community-Acquired Pneumonia

What is CAP?

CAP (Community-Acquired Pneumonia) is the most common type of pneumonia. It occurs outside the hospital and in the community.

Pneumonia that occurs in hospitals and healthcare facilities is called “Health Care-Associated Pneumonia”.

Our team’s research focus is CAP. Pneumonia is a lung infection caused by bacteria, viruses (like influenze, RSV and COVID) or fungi.

Pneumonia causes the air sacs in the lungs to fill with fluid or pus that can cause cough, make breathing difficult and lower oxygen levels.

Pneumonia in Children

Pneumonia can range in severity from mild to life-threatening. Pneumonia is most serious in infants, young children, people older than age 65, and people with chronic illnesses, health problems or weakened immune systems.

People at Risk

Newborns and infants may not have the same symptoms as adults. They may:

  • vomit,
  • have a fever,
  • cough,
  • appear restless,
  • tired and lack energy,
  • have difficulty breathing and eating.


Indigenous people have an increased risk of pneumonia because they have more frequent underlying conditions like diabetes, chronic lung disease, heart disease and kidney disease.

Symptoms include:

  • Fever and chills,
  • Cough with or without phlegm that can be clear, white, yellow or green,
  • Shortness of breath,
  • Chest pain when breathing,
  • Fatigue,
  • Nausea,
  • Vomiting,
  • Diarrhea,
  • Confusion in people over 65.
