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 to inform them that you may have measles. This will allow healthcare staff to take the appropriate precautions to prevent further spread of measles.
Niagara Health reminds the public that measles is highly contagious, remaining in the air for up to two hours after an infected person has left the area. If you suspect you or a loved one has measles and needs emergency medical attention, please call ahead to 905-378-4647 and press 0 before you come to the hospital to help protect other patients, visitors and staff. Niagara Health has strict infection prevention protocols in place to ensure the safety of everyone in our care.
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."
