Abstract
Background: The novel disease caused by the new coronavirus SARS-CoV-2 has caused
an unprecedented global pandemic. Care providers of asthmatic children are increasingly
con-cerned; as viral infections are one of the primary triggers of asthma flare-up.
However, the effect of SARS-CoV-2 as well as the generated worldwide lockdown on
asthmatic children is unknown.
Objective: The aim of this study was to analyze the effects of pandemic SARS-CoV-2 in
pediat-ric asthma control.
Material and Methods: A retrospective, open, transversal study was performed at five
ter-tiary hospitals. Recruited patients were aged <18 years and had physician-diagnosed
asthma. Information regarding the 2019 and 2020 seasons were provided.
Results: Data were collected from 107 children (age range: 3–18 years, mean age: 12
years). Well-controlled asthma was observed in 58 (54.2%) patients in 2020 versus 30 (28%)
in 2019, and 15 (14%) patients had poorly controlled asthma in 2020 versus 28 (26.2%) in 2019.
In 2020, a decrease in exacerbations caused by allergies to pollen, dust mites, molds, and
through other causes not related to SARS-CoV-2 infection was observed. An increase in
exacerbations was observed due to animal dander, stress, physical exercise, and SARSCoV-
2 infection
