Several things: Avoidance of crowds, friends and family with colds during the winter when colds are most highly prevalent. Also the use of an inhaled steroid along with an inhaled long-acting bronchodilator (Serevent, Spiriva or both).
Pay more careful attention to your respiratory health so that, when you first sense the onset of a cold, the very first signs, you can contact your doctor and arrange to initiate oral steroid and/or antibiotic therapy.
Finally, avoid the agony of Influenza by getting a Flu Shot soon.
