Clinical Insights and Advancements in Human Metapneumovirus Management and Prognosis.

Human metapneumovirus is a respiratory pathogen that infects children, the elderly, and immunocompromised individuals. Despite its global prevalence, underdiagnosis persists because of clinical overlap with other respiratory viruses. The current approach is mostly supportive, with oxygen therapy and hydration being crucial interventions. Ribavirin contains antiviral properties but has little clinical application. Vaccine development is moving forward, with prospects including live-attenuated, subunit-based, and virus-like particle vaccines. Molecular diagnostics, such as RT-PCR and metagenomic sequencing, have increased detection rates, which aids epidemiological monitoring. Monoclonal antibodies targeting the fusion (F) protein are being studied for passive immunity, while immunomodulatory treatments such as corticosteroids and intravenous immunoglobulins may help treat severe cases. Emerging treatments include fusion inhibitors and pan-pneumovirus vaccinations that protect against HMPV and RSV. Future research should concentrate on optimizing antiviral methods, increasing vaccination trials, and improving surveillance to detect outbreaks. A multidisciplinary approach that combines virology, immunology, and epidemiology is required to reduce HMPV's effect and improve patient outcomes. This review serves as a comprehensive literature about HMPV which provides all the crucial clinical perspectives and the latest advancements in management, antivirals, patient prognosis as well and diagnostic modalities.
