Early-Life Viral Lower Respiratory Tract Infections and Their Impact on Childhood Asthma: Molecular Endotypes and Prevention Strategies

It highlights molecular and immunological endotypes of virus-induced asthma and explores the influence of genetic, epigenetic, and microbial factors. Emerging diagnostic tools and preventive strategies-including vaccines, monoclonal antibodies, environmental interventions, and microbiome-targeted therapies-are also discussed as means to reduce the global pediatric asthma burden and improve respiratory health.
