Who is most likely to catch norovirus?

ANSWER

Young children, the elderly, and people who have a weakened immune system are particularly susceptible to catching norovirus. The spread of the virus can be hard to control because it's contagious before symptoms appear. In other words, you can spread the infection before you know you’re sick.

For example, one or two kids in a classroom with norovirus can wipe out the whole class -- and other classrooms as well. If one person in a household gets it, the whole family gets it.
