Since its discovery in 2001, Human Metapneumovirus (hMPV) has been identified globally, exhibiting predictable seasonal outbreaks primarily affecting young children, the elderly, and individuals with preexisting health conditions. The virus is transmitted through airborne droplets and is responsible for a notable percentage of respiratory illnesses, particularly in children under five years of age, with hospitalization rates peaking in the first year of life. The complex immune response elicited by hMPV, characterized by a Th17-like profile and excessive mucus production, contributes to respiratory complications, emphasizing the need for effective management strategies. This review discusses various diagnostic methods, emphasizing the potential of combining serology with RT-PCR to enhance diagnostic accuracy during outbreaks. Furthermore, it addresses the therapeutic approaches, including the promise of recombinant interferons and ongoing research on the use of passive immunity through neutralizing antibodies. A comprehensive overview of hMPV, emphasizing the importance of continued research to improve diagnostic and therapeutic options for this significant respiratory pathogen, offers promising strategies for manipulating responses through targeted interventions.
