Abstract:
Asthmatics are particularly vulnerable to viral illnesses, which cause the vast majority of asthma exacerbations. The most common viruses
responsible for these exacerbations are the human rhinovirus and influenza virus. Influenza vaccine provides a reasonable prevention
strategy for influenza infection, but there is not an effective vaccine against the rhinovirus. This is a major reason for effective control of
chronic asthma and strategies to prevent viral upper-respiratory tract infections in asthmatics. COVID-19 does not appear to be more severe
in asthmatics, especially if they are well controlled. This virus also does not seem to be more common in asthmatics. However, in times of
pandemic virus diseases, it is necessary that asthma and allergic rhinitis are well controlled. It is important to distinguish COVID-19 from
asthma exacerbations, because the treatments differ. Asthma therapies are not contraindicated in COVID-19-infected patients, as adverse
events do not occur in this group.
