Many major cities around the world have modern health facilities and often have English speaking doctors. However, rural areas might lack proper facilities. In some areas, it might be necessary to travel to a major city center for medical attention.
Some countries will not have modern facilities and equipment; however, it would be prudent to research the countries in question and find out if they do have proper medical facilities. Contact the nearest embassy and inquire as to the medical facilities and their reliability. It is recommended that you speak to teachers in the area and discuss their experiences.
