Human metapneumovirus in children with acute lower respiratory infections: effects on clinical and disease severity

HMPV infections were primarily observed in summer and autumn During 2023-2024. Our findings underscore the importance of early identification of severe and potentially fatal HMPV-associated ALRI in pediatric populations. Given the observed seasonal pattern and the risk of severe outcomes-particularly among children with underlying conditions-timely diagnosis and risk stratification are critical for guiding clinical management and informing targeted public health interventions.
