How do pandemics spread internationally?

Explanation:

They can be spread by people traveling, such as cruise ships and planes. They can also be spread if the pandemic started from foods, if those foods are imported and exported to different countries, same thing for animals. Hope this helps :)

was there more to the question like a picture or something? also i mean with no picture i think something that's not likely to be an educational impact would probably be the way the child is raised since it has special health care needs
