Failure to Reach Equilibrium with a Disease Agent Could Result

Question

Failure to reach equilibrium with a disease agent could result in extinction for a host species.

Accepted Answer

If a host species is unable to reach equilibrium with a disease agent, it will continue to suffer from the negative effects of the disease. Over time, this could lead to a decline in the population size and, ultimately, extinction if the host species is unable to adapt or develop immunity to the disease.
