What is thunderstorm asthma?

Thunderstorm asthma is believed to be a result of high amounts of grass pollen in the air and a certain type of thunderstorm.

For people who have asthma or hay fever, this can trigger severe asthma symptoms.

When a large number of people develop asthma symptoms in a short period of time, this is known as epidemic thunderstorm asthma.

How do I protect myself?

Health authorities urge anyone who suffers from asthma or hay fever to monitor the forecast on the VicEmergency app.

Avoid being outside during a storm and especially during the winds prior to the storm.

Take preventative medication as directed by your GP even if you're symptom-free.

Always carry your reliever and be aware of how to manage your asthma attack, your GP can help you with this.
