Consequences of COVID 19 Pandemic on Childhood Asthma
Consequences of SARS-CoV2 Pandemic on Childhood Asthma Control and Exacerbations: French Multicenter Cross-sectional VIRASTHMA COVID G4 Study
Source: ClinicalTrials.gov · Last updated 14 May 2026
Brief summary (registry, in English)
The SARS-CoV2 pandemic, which emerged in the first quarter of 2020, has led to an unprecedented health crisis in our modern healthcare systems and has resulted in strong national public health measures. The impact of the pandemic and its indirect environmental consequences on pediatric asthma is currently being assessed. In particular, the study of its role on the risk of exacerbations and modification of control is one of the priority research objectives defined by European societies. The primary aim is to study the impact of the pandemic on asthma control in children aged 3-16 years with a medical diagnosis of asthma, compared to data from other observational cohorts conducted in the same region prior to the pandemic. A sub-population of children 3-16 years will be assessed at exacerbation and at a follow-up visit, 2-4 months later, with clinical data, biological and microbiological samples.
