  • Avoid all contact with people at risk of complications:

    • Children under a year old

Information about measles

Measles is a very contagious disease caused by a virus that spreads through the air on droplets from the nose and throat of an infected person. The first symptoms of measles are the following:

  • High fever
  • Runny nose
  • Cough
  • Conjunctivitis (red eyes)
  • General discomfort

Next a rash appears on the face and then spreads to the body

It can take 7 to 14 days (exceptionally up to 21 days ) between exposure to the measles virus and onset of symptoms. This is called the incubation period. A person is considered to be contagious 4 days before the rash appears and can remain contagious up to 4 days after. Measles lasts 1 to 2 weeks.

Importance of getting vaccinated

The public health department would like to remind the public that vaccination is the best way to protect against measles. Anyone who has never been vaccinated against measles or who has never had the illness should also get vaccinated. It’s the best way to protect yourself and others.
