The COVID19 pandemic is having an immeasurable impact on the economy and on morbidity andmortality. Knowledge and scientific evidence about this disease is advancing rapidly, butit is not yet known whether asthmatic patients suffering from COVID19 have anexacerbation of asthma, or whether this viral infection has an impact on control and lungfunction in the short to medium term.The aim of this study is to define the changes that occur in these two parameters inasthmatic patients suffering from COVID19. To this end, asthmatic patients who havesuffered a SARS-CoV-2 infection and who have required an emergency consultation orhospitalisation will be collected in a pneumology consultation and matched by age, sexand severity of asthma with a group that has not suffered the same. Both will be followedfor one year, and lung function will be tested at six months and exacerbations andchanges in ACT during the following year.These data are intended to improve the available knowledge on the impact of IDVC19 onasthma patients with a view to making appropriate recommendations, prevention andtreatment adjustments in line with the results obtained.
