what is the term used to describe the disease producing power of a microorganism
Virulence In the context of gene for gene systems, often in plants, virulence refers to a pathogen's ability to infect a resistant host.[1] In most other contexts, especially in animal systems, virulence refers to the degree of damage caused by a microbe to its host.[2] The pathogenicity of an organism - its ability to cause disease - is determined by its virulence factors.[3] The noun virulence derives from the adjective virulent. Virulent can describe either disease severity or a pathogen's infectivity.[4] The word virulent derives from the Latin word virulentus, meaning "a poisoned wound" or "full of poison."[4][5]
Non-communicable disease A non-communicable disease (NCD) is a medical condition or disease that is not caused by infectious agents (non-infectious or non-transmissible). NCDs can refer to chronic diseases which last for long periods of time and progress slowly. Sometimes, NCDs result in rapid deaths such as seen in certain diseases such as autoimmune diseases, heart diseases, stroke, cancers, diabetes, chronic kidney disease, osteoporosis, Alzheimer's disease, cataracts, and others. While sometimes referred to as synonymous with "chronic diseases", NCDs are distinguished only by their non-infectious cause, not necessarily by their duration, though some chronic diseases of long duration may be caused by infections. Chronic diseases require chronic care management, as do all diseases that are slow to develop and of long duration.
