The increasing prevalence of allergies and asthma has become a significant global socioeconomic burden. The COVID-19 pandemic has dramatically changed the health and lifestyles of children and adolescents, but its impact on allergies and asthma remains unclear due to limited studies. This article aims to explore the differences in the prevalence of allergies and asthma among children and adolescents before during and after the COVID-19 pandemic, using data from various regions. COVID-19 increases the risk of new-onset asthma, and vaccination may reduce this risk by preventing COVID-19, particularly in older individuals. Further research is needed to explain these finding. Data were core databases and supplemented by browsing health information journals and citation searching. Asthma It is the most common chronic respiratory disorder in children, is a heterogeneous disease characterized by chronic airway inflammation and hyperresponsiveness that causing repeated cough, wheezing, chest tightness and shortness of breath, with prevalence approximately 14% of children worldwide, a prevalence much higher than that among adults (7.7%) [1] The purpose of this study is to investigate the incidence of asthma in children before and after the COVID-19 pandemic and explore potential contributing factors. Asthma diagnosis rates, demographic factors, and environmental exposures were compared. The study included Children and adolescents Adolencents with a documented diagnosis of asthma (ICD-10 code J45) were included. Exclusion criteria included pre-existing chronic respiratory conditions other than asthma.
