Health alert: thunderstorm asthma warning for Victoria

Do you suffer from asthma or hay fever? Health authorities are warning that you may be at increased risk of thunderstorm asthma over the next few days, as storms develop from today, Thursday 28 October.

High-risk areas include the Mallee, South-West and Wimmera weather districts, but the entire state could be affected.

If you’re at risk, it’s recommended that you stay indoors as much as possible during this time to avoid developing asthma symptoms. You should also know that thunderstorm asthma can affect anyone – even if you’ve never experienced symptoms of asthma or hay fever before.

What exactly is thunderstorm asthma?

Thunderstorm asthma can occur when typical spring conditions – hot, dry, windy and stormy weather – cause pollen grains to break into tiny pieces. If you breathe in these pieces, they can get deep into your lungs and lead to an asthma attack.

Symptoms are like those of asthma, but they’re more intense. They can include breathlessness, a tight feeling in the chest, wheezing and coughing. These symptoms can also escalate quickly and dangerously. 

The highest risk period is from October to December, and you’re not only at risk when there’s a storm – thunderstorm asthma can occur on hot and windy days too.

How can I prevent and treat thunderstorm asthma?

It’s best to speak to a doctor if you’re experiencing new symptoms and want advice – free appointments are available at the Deakin Medical Centre.

You should also educate yourself, know the triggers and symptoms, and have an action plan if needed:

Is it asthma/hay fever – or COVID-19?

While symptoms like a sore throat, runny nose and cough are common indicators of hay fever, they’re also linked to COVID-19. If you usually suffer from asthma or hay fever, ask yourself if there’s any difference between your usual reactions and any other symptoms that could be viral in nature.

Dr John Blakey, respiratory clinician and medical adviser to Asthma Australia, highlights the key differences, including the way symptoms change over time. While hay fever is usually triggered by something in the environment, and symptoms of both asthma and hay fever tend to come and go, the symptoms of a virus will generally worsen over time.

Dr Blakey says that regular sufferers of asthma or hay fever should take note of any changes to their usual patterns of symptoms and seek medical assistance if something seems different to normal. It’s also important to get on top of any asthma symptoms early, so other problems like COVID-19 are easier to spot.

And remember: if you’re unsure about your symptoms or you’re feeling unwell, make sure you get tested for COVID-19 straight away.
