Which term describes a disease that is easily spread from one person to another?

The term that best describes a disease that is easily spread from one person to another is "contagious." Contagious diseases are transmitted through direct contact with an infected person or through items they have used or handled, as well as through respiratory droplets when an infected person coughs or sneezes. The high likelihood of transmission highlights the need for proper sanitation and hygiene practices in environments where individuals may come into close contact.

In contrast, chronic diseases refer to conditions that are long-lasting and often progressive, such as diabetes or heart disease. They are not necessarily spread from person to person. Endemic diseases are those that are consistently present within a certain geographic area or population, like malaria in certain regions, but this does not imply that they spread easily from one individual to another. Acute diseases, while they can be severe and occur suddenly, do not inherently imply ease of transmission; they could be caused by various factors and not all acute conditions are contagious.
