A rare condition known as thunderstorm asthma sent hundreds to hospitals in Australia's second-largest city of Melbourne, and four deaths had been confirmed.
A wild thunderstorm Monday night caused rain-sodden ryegrass pollen to explode and spread over the city.
The pollen caused asthma attacks in some patients who'd never suffered from asthma before.
One ambulance company responded to nearly 19-hundred calls.
