A deadly virus that has claimed the lives of local villagers has been traced to the spotted fruit bat, in which the virus resides between periodic outbreaks. Biologists speculate that the bat might also be one of the reservoirs for a number of other viruses that have led to village fatalities. The local government has proposed to eliminate the spotted fruit bat by cutting off passageways that allow the bat to emerge from its caves. Once the bat is unable to emerge from the caves, the government will have achieved its objective of reducing the number of village deaths attributable to viruses.
