Improved treatment adherence and allergic disease control during a COVID-19 pandemic lockdown.

Modern hectic lifestyles have created challenges for parents of allergic children, as treatment adherence and optimal disease control are closely tied to adequate caregiver supervision. Environmental allergens exposure in schools and outdoor environments are also difficult to control but impacts disease outcomes.1 Improvements in disease symptoms are often reported during school vacations,2 when children have more time at home under a caregiver's supervision. This study aimed to evaluate the impact of an 8-week (April to June 2020) COVID-19-induced nation-wide lockdown in Singapore on allergic disease control in children. Universal masking and movement restrictions (closure of schools, workplaces, retail and entertainment facilities) were implemented. This presented a unique opportunity to evaluate the impact of increased caregiver supervision, school closures, reduction of outdoor exposures and increased indoor time on allergic diseases control.
