Unraveling the Impact of Human Metapneumovirus (hMPV) on Pediatric Respiratory Health in India

Human metapneumovirus (hMPV) is an emerging respiratory pathogen first identified in 2001, belonging to the Paramyxoviridae family. It predominantly affects pediatric populations, leading to a spectrum of respiratory illnesses ranging from mild upper respiratory infections to severe lower respiratory conditions such as bronchiolitis and pneumonia. While hMPV can infect individuals of all ages, young children and immunocompromised individuals are particularly vulnerable, often requiring hospitalization. The virus is classified into two primary subtypes, A and B, with genetic variations influencing disease severity and epidemiological trends.In India, recent surveillance has identified confirmed cases of hMPV, emphasizing the need for enhanced public health monitoring. The Indian Council of Medical Research (ICMR) has reported cases in Karnataka, underscoring the virus's circulation in the country. Despite its clinical significance, no specific antiviral treatment or vaccine is currently available, and management remains supportive, focusing on symptom relief and respiratory support in severe cases. This study explores the epidemiology, clinical manifestations, diagnostic methods, and treatment strategies for hMPV, with a particular focus on its impact on pediatric respiratory health in India. Understanding the virus’s prevalence and disease burden is essential for guiding public health policies and developing targeted preventive measures.
