Communicable and noncommunicable diseases differ in how they spread, with preventions methods tailored to each type.
Communicable diseases are spread from person to person through various means like air, touch, or contaminated objects. Examples include the flu and tuberculosis. Noncommunicable diseases are not infectious and do not spread between individuals. They are often caused by factors like genetics, lifestyle, and environment. Examples are diabetes and cardiovascular disease.
Prevention methods like washing hands to avoid communicable diseases and having a regular, healthy diet to prevent noncommunicable diseases are crucial. Similarly, staying home when sick applies to communicable diseases to prevent their spread.
