"Persistent asthma" refers to a medical condition where a person experiences ongoing or long-lasting symptoms of asthma. This means that someone with
persistent asthma might have asthma symptoms regularly, even when they are not being triggered by specific factors like allergies or exercise. It's a condition that requires ongoing management and treatment to help control and relieve the symptoms.
