Epidemiological triad is ................
Answer: A
The epidemiological triad is agent, host and environment.
The triad explains disease as the interaction of an agent (a microbe, nutrient deficiency or chemical), a susceptible host with its own age, immunity and behaviour, and an environment that brings them together. Disease occurs when the balance among the three is upset.
A vector is a means of carrying the agent between hosts and belongs to the environment side, so it does not replace one of the three. A carrier is a kind of host. Treatment is a response to disease, not a cause in the model.
