  Effects of predators of juvenile mice on the spread of the Hantavirus are
analyzed in the context of a recently proposed model. Two critical values of
the predation probability are identified. When the smaller of them is exceeded,
the hantavirus infection vanishes without extinguishing the mice population.
When the larger is exceeded, the entire mice population vanishes. These results
suggest the possibility of control of the spread of the epidemic by introducing
predators in areas of mice colonies in a suitable way so that such control does
not kill all the mice but lowers the epidemic spread.
