World Cup 2026 Health Risks: What Canadians Need to Know About Infectious Diseases

The 2026 FIFA World Cup kicks off on June 11, 2026, and millions of fans will gather in 16 cities, including Vancouver and Toronto. But health experts warn that mass crowds and international travel create ideal conditions for infectious diseases to spread.

Here is what you need to know to stay safe.

The key impact for Canadians

If you plan to attend World Cup matches, use public transit in host cities, or live near stadiums, your risk of catching measles, flu, or COVID-19 is higher than usual.

Measles cases are surging across North America. As of June 2026, the U.S. has confirmed over 2,000 cases. The flu season has hit a 30-year high. COVID-19 is still circulating.

Dramatic threats like Ebola are considered very low risk due to travel bans and screening. The real dangers are the common illnesses that spread easily in crowded indoor spaces.

What you should do

Take these steps to protect yourself and your family:

Check your vaccinations. Make sure your measles, mumps, and rubella (MMR) vaccine is up to date. If you are unsure, ask your doctor or local public health unit.
Get a flu shot. It is not too late. Flu season is severe this year.
Consider a COVID-19 booster. If you are eligible, get one before the tournament starts.
Wear a mask in crowded indoor spaces. This includes stadiums, airports, trains, and buses.
Wash your hands often. Use soap and water or hand sanitizer.
Stay home if you feel unwell. Do not attend matches or gatherings if you have symptoms like fever, cough, or sore throat.
Follow local health advisories. Check your city’s public health website for updates.

Who is affected

Canadians attending World Cup matches in Vancouver, Toronto, or any host city.
People living near stadiums or transit hubs in host cities.
Travelers flying into Canada from other countries during the tournament.
People with weakened immune systems or underlying health conditions.
Children under five and older adults who are more vulnerable to measles and flu.

Bottom line

The 2026 World Cup is an exciting event, but mass gatherings increase the risk of spreading measles, flu, and COVID-19. The good news is that these illnesses are preventable. Get your vaccines, wear a mask in crowds, wash your hands, and stay home if you are sick. A few simple steps can help you enjoy the tournament safely.
