The three main components of the epidemiological triad are:

1. Host: This refers to the organism that harbors the disease. It can be humans, animals, or plants. The host's characteristics, such as age, sex, health status, and behaviors, can influence the likelihood of disease exposure, susceptibility, and response.

2. Agent: This is the pathogen that causes the disease. It can be a virus, bacteria, parasite, or other microbe. The agent's characteristics, such as its virulence, infectivity, pathogenicity, and mode of transmission, can influence its ability to cause disease.

3. Environment: This refers to the external factors that affect the agent and the opportunity for exposure. It can include physical factors like weather and geography, biological factors like insects that transmit the disease, and social factors like sanitation, access to health care, and population density.

Zoonosis is not a component of the epidemiological triad. It is a term used to describe diseases that can be transmitted from animals to humans.
