Question:How do previous infections affect my risk of developing asthma?
Answer: Infections in asthma really come to childhood exposures and the development of asthma later on. Kids who have had repeated viral infections like colds, flus, upper airway infections -- they seem to be at an increased risk for asthma.
It's thought that these viruses cause some change in the airway that make them more irritable. And as adults with asthma, viral infections can cause asthma attacks and more commonly it's a viral infection that results in an asthma exacerbation then it is going to be a bacterial infection.
