Symptoms of measles

Measles symptoms often start with a cough, runny nose, red watery eyes, and fever. About three to seven days after symptoms begin, a rash that looks like small red spots develops on the face and spreads down the body. Small, white spots may also appear inside the mouth.

Measles is a highly contagious respiratory virus. It spreads easily when an infected person breathes, coughs, or sneezes.

What to do if you suspect measles

If you or someone in your household develops measles symptoms, please stay home and avoid attending work, school, or any community activities. Contact your health care provider. Make sure to call ahead before going to your doctor’s office or emergency department to inform them that you may have measles. This will allow health care staff to take the appropriate precautions to prevent further spread of measles.

People who are not up to date with their measles vaccination or who have not previously had measles are at highest risk of infection. Public Health is urging residents to make sure they are up to date with all their vaccinations. If you need a measles-containing vaccine, see your health care provider or go to a walk-in clinic.

"It’s important to remember that measles is a serious disease that can lead to severe complications, particularly in young children, older adults, and those with weakened immune systems,” said Niagara Region’s Medical Officer of Health, Dr. Azim Kasmani. “We urge residents to protect themselves, their families, and their community by ensuring they are vaccinated."

Increasing cases – stay informed

As the number of cases is likely to increase, Public Health encourages residents to stay informed. Please visit the Niagara Region Public Health website for information about measles, a list of all known recent measles exposure locations and timelines, and vaccination guidance.
