We are having an on and off wet and cold winter this year. Many patients are contacting our office regarding viral upper respiratory infections, which may affect their asthma. The common cold is most often caused by the rhinovirus, but this time of year corona viruses are also active, as well as the echo and coxsakie virus. RSV strikes not only children but adults also, causing an asthma like condition with wheezing and coughing. We also have had a considerable number of influenza cases in Tucson; and even though many patients have had their flu shot, this year the flu shot has been gauged to be about 62% effective. Wash your hands frequently, and try to avoid large crowds. It is hard to predict how the upcoming Spring allergy season will be, but we will have appointments available with minimal wait time as we have 5 physician specialists available on our staff.
