Thunderstorm asthma events are believed to be triggered by an uncommon combination of high rye grass pollen levels and a certain type of thunderstorm.
About 75% of people with asthma also have allergic rhinitis (hay fever), and about 25% of people with allergic rhinitis also have allergic asthma.
Symptoms of a viral illness can be similar to the symptoms of allergic rhinitis (congestion or runny nose) and asthma (cough, difficulty breathing and shortness of breath).
ALWAYS give adrenaline device FIRST, and then asthma reliever puffer, if someone with known asthma and allergy to food, insects or medication has sudden breathing difficulty.
