WebInfection with JEV can cause Japanese encephalitis (JE), a severe disease with a high mortality rate, which also results in ongoing sequalae in many survivors. The natural reservoir of JEV is ardeid wading birds, such as egrets and herons, but pigs commonly play an important role as an amplifying host during outbreaks in human populations. WebEvolution. Evolution is the change in characteristics of populations of organisms over time. Changes can be small, for example, a small change in body size or a change in the color of a species’ fur.
