Medical diplomacy is a type of international diplomacy that lets countries work together to share knowledge and resources so that people around the world can have better access to healthcare. This kind of diplomacy helps to show that countries care about the people of other countries and want to work together to make sure everyone has the medical care they need. For example, countries might send teams of doctors to help take care of people in places that don't have enough doctors or hospitals. They might also share medical supplies like medicine or vaccines, and share information about healthcare so everyone can learn how to stay healthy. Medical diplomacy helps the world stay healthy, because when people in one place have access to healthcare, it helps people in other places too!
