Measles is highly contagious. It is an infection that is caused by a virus.
If you develop symptoms, seek medical care if needed, but call ahead to allow health care staff to manage your case appropriately.
Measles is spread easily through the air or through contact with droplets from the nose and throat of an infected person when they cough or sneeze.
The virus can stay in the air for long periods of time and infect others in the same room or in neighbouring rooms.
Persons infected with measles can spread it to others four days before to four days after the rash appears.
