Eight now dead from thunderstorm asthma

The death toll from Melbourne's freak thunderstorm asthma event has risen to eight after a further two people died in intensive care.

The Department of Health says one person is still in a critical condition in hospital and six others are getting specialist care after the storm on Monday last week.

Every available ambulance in Melbourne was sent out on calls during the storm, and more than 8500 people were admitted to hospital. - AAP
