Which term refers to an organism that causes disease?

Explanation:
A disease-causing organism is called a pathogen. This name specifically identifies the organism responsible for illness, whether it’s a bacterium, virus, fungus, or parasite. Transmission refers to how a disease spreads, not what causes it. Endemic describes a disease that is regularly found in a population or area, and a vaccine is something that helps build immunity against a disease. So, the term that best names the agent behind the illness is pathogen. For example, influenza A virus is a pathogen that can cause flu in humans.
