Amalia has the flu, a communicable disease that causes a cough and a runny nose. Which best describes how she likely got it?

The flu is communicable, meaning it can spread from one person to another through germs. Those germs can remain on shared surfaces, such as a classroom doorknob, and spread when someone touches the surface and then their face. Not exercising or having a poor diet does not directly cause the flu, and it is not inherited from parents.
