Which term describes diseases that are caused by pathogenic microorganisms?

The term that describes diseases caused by pathogenic microorganisms is infectious diseases. These diseases can be transmitted from one individual to another, either directly or indirectly, and are typically caused by bacteria, viruses, fungi, or parasites. Infectious diseases have the potential to spread and can lead to outbreaks in communities, making understanding them critical for public health and infection control.

Contagious diseases, while also caused by pathogenic microorganisms, specifically refer to infections that can be easily spread from person to person, often through respiratory droplets or physical contact. Non-infectious diseases, on the other hand, are not caused by microorganisms and can result from factors like genetics, lifestyle choices, or environmental exposures. Chronic diseases are long-lasting conditions that usually develop slowly and can be caused by a variety of factors, but do not fall under the category of infectious diseases.
