An infectious disease is a disease that is caused by what?

Answer 1

Infectious Diseases are those diseases which are caused by infectious agents (which include microorganisms such as bacteria, fungi, protozoa and virus, as well as some multicellular animals such as worms) and hence they are the ones which can spread from one person to another. Non-infectious diseases are those diseases that are not caused by infectious agents and do not spread from one person to another.

Answer 2

Obtaining the appropriate body fluid (e.g. blood, sputum, urine, etc.) and plating it out in the lab usually yields the relevant causative organism needing to be treated.

Answer 3

infectious diseases result from uncovered wounds getting bacteria in them.

Answer 4

An infectious disease is a disease caused by pathogenic microorganisms such as bacteria, viruses, fungi, or parasites. These organisms can be spread directly or indirectly from one person to another.

Answer 5
