If you have been asked to stay home in quarantine, this is to prevent you from spreading the measles virus to others if you are developing the disease. People are able to pass on measles before they become unwell.
While in quarantine please stay home and stay away from others. Do not go to work, school, preschool, or public places where you could pass on measles. Do not use public transport or visit friends or family. Avoid being in the same room as people who are not immune to measles.
