Yes: Asthma is a condition where your airways are overly ("hyper") responsive. It can newly occur in adults, especially after an upper or lower respiratory infection. However, all that wheezes is not asthma. You may have a different lung disease. You may need to have special tests (such as pulmonary function testing) by a specialist to be sure what your diagnosis is.
