The virus can live on surfaces and in the air for up to two hours after the infected person leaves. It can also be contracted through direct contact with secretions from the person's mouth or nose.
Those with measles can spread the virus to others five days before they get the tell-tale rash and four days after it disappears.
Measles can cause long-term health issues in the lungs, ears, or brain.
