A Non-Native Mosquito Species Moves North into the United States

A non-native mosquito species moves north into the United States, carrying with it a viral disease that affects humans.Epidemiologists, who track disease outbreaks, want to predict both the spread of the disease in humans and how serious its effect will be.Given that it is a new (introduced) virus, how will its effect likely compare with that of a viral disease spread by a native mosquito?

A) It should be no different, since both diseases are carried by mosquitoes.
B) It should cause a less serious disease, since it is not adapted to the area.
C) It should cause a less serious disease, since there are fewer of the new mosquitoes.
D) It should cause a more serious disease, since it will spread faster than a native virus.
E) It should cause a more serious disease, since no humans are adapted to it.
