Conclusion

There are neither consistent evidence that patients with asthma are at greater risk of becoming infected by SARS-CoV-2 nor that they are at greater risk of having poor outcomes of COVID-19. On the contrary, there are reports indicating patients with asthma may be at lower risk of hospitalizations during the COVID-19 pandemic. The reasons behind these observations may be various, related to asthma and its treatment, related to patient's behavior, related to the health system and related to collective changes in pattern of activities. It is likely that reduction in acute respiratory infections because of social distancing, use of face masks and hand washing has a major role in the observed reduction in asthma hospitalizations because of the prevention of common colds. Management of asthma in times of COVID-19 must be optimized, medication has to be used regularly and exacerbations shall be detected early to be halted. Systemic corticosteroids may be used as required, for control of severe asthma or severe exacerbations. Patient education on an action plan for asthma attacks is crucial, as well as facilitating communications with the healthcare team for unscheduled visits or teleconsultations. Observations from the pandemic scenario on different causes for the reduction in asthma morbidity must be investigated to inform future strategies for prevention of asthma attacks.
