Communicable diseases are diseases which are spread from one person to another via the air, water or physical contact. Definable differences exist between low and high-income countries. People who live in high-income countries have access to better health care facilities, as well as access to better nutrition. A good example of how communicable diseases spread faster in low-income countries is the latest outbreak of Ebola in Africa. People died in their thousands in Africa.
