Welcome to the Voice of America’s News Words.
In the grain-growing region of the Australian state of New South Wales,
millions of mice are causing widespread destruction.
The plague of mice has forced hundreds of prisoners and workers from a prison while repairs are made to damaged walls and electrical wiring.
The mouse plague is caused by the effects of weather, wildfires and a plentiful grain crop.
In this example, a plague is a large number of harmful and troublesome things.
Plague can also mean a deadly disease that spreads quickly to a large number of people.
