When it comes to referring to a disease or illness that cannot be transmitted between people, there are several synonyms for the term "non-communicable." One commonly used term is "chronic," which refers to a long-lasting condition such as diabetes or heart disease. Another synonym is "non-infectious," which indicates that the illness cannot be spread through physical contact or exposure to bodily fluids. Additionally, "lifestyle-related" or "behavioral" diseases are terms used to describe conditions that result from unhealthy habits or choices, such as smoking or a poor diet. Regardless of the specific synonym used, the term "non-communicable" indicates that the condition cannot be transferred from person to person.
