What kind of disease is defined as easily transmitted from one person to another?

The term that refers to a disease that is easily transmitted from one person to another is "contagious disease." These diseases are typically caused by infectious agents such as bacteria, viruses, or fungi and can spread through direct contact with an infected individual, through droplets in the air when a person coughs or sneezes, or via surfaces and objects that have been contaminated. Understanding this definition is crucial in fields such as public health and epidemiology, where controlling the spread of contagious diseases is a primary focus to prevent outbreaks.

Non-contagious diseases, on the other hand, do not spread between individuals and are typically caused by genetic factors, lifestyle choices, or environmental influences. Chronic diseases refer to conditions that are long-lasting and usually progress slowly, while genetic diseases are inherited and caused by abnormalities in an individual's DNA. These categories help distinguish the nature of diseases and inform appropriate prevention and treatment strategies.
