Annika’s little brother has the flu. Annika has a busy week at school, and she really does not want to get sick. What can Annika do to stay healthy?

The flu is not communicable, so she does not need to worry about it.

She should wash her hands often and stay away from her brother as much as possible.

She should follow whatever treatment her brother is on so that she can cure it before she gets it.

She should hang out in the same room with her brother so that she can begin to build immunity.
