International health is when doctors and nurses work together to help lots of people who live in different countries to stay healthy.
Imagine you have a lot of friends who live in different parts of the world. Some of them might live in places where there aren't very many doctors or hospitals. Some of them might not have enough money to buy healthy food or medicine when they get sick.
International health means that doctors and nurses try to help all of these friends to stay healthy, no matter where they live, or how much money they have. They might do this by traveling to different countries to give people check-ups, vaccinations, or medicine. They might also teach people how to stay healthy by eating healthy food, washing their hands, and exercising.
International health is important because everyone deserves to be healthy, no matter where they live or how much money they have. By working together, doctors and nurses can help make sure that people all around the world are able to live healthy and happy lives.
