The WHO and UNICEF estimated that measles vaccination coverage in Canada was 92 percent in 2023, within the 92-95 percent required to prevent wider community transmission. Health officials reported 12 measles cases nationwide in Canada in 2023, 3 cases in 2022, and no cases in 2021.
Measles is a very contagious viral disease that spreads through respiratory droplets created when an infected individual coughs, sneezes, or speaks. Infected individuals can also expose people around them by contaminating surfaces with secretions from the nose, mouth, and throat. Symptoms typically appear 7-14 days after exposure but can develop up to 21 days after exposure. Symptoms generally include fever, cough, runny nose, red eyes, and a red rash that begins on the face and spreads downward. Serious complications - including pneumonia - can occur, especially in children younger than five years old, adults older than 20 years old, and individuals with a weakened immune system.
