List of Infectious Diseases

An infectious disease (pronounced: /ɪnˈfɛkʃəs dɪˈziːz/) is a medical condition caused by the invasion of an organism's body tissues by disease-causing agents, their multiplication, and the reaction of host tissues to the infectious agents and the toxins they produce. The term is most often used to refer to diseases that are caused by microorganisms, such as bacteria, viruses, and parasites.

Etymology

The term "infectious disease" comes from the Latin word infectus, which means "to infect", and the Greek word disease, which means "lack of ease".
