An animal or a bird can serve as a host for a disease by carrying insects on its body or by harboring microorganisms in its bloodstream. If the hosts can survive this way, they may also become a reservoir of the disease. Consider Lyme disease, identified in 1975 and named for Lyme, Connecticut, U.S.A., where it was first observed.
