    Human metapneumovirus (hMPV) was identified in 2001 and is a significant cause of respiratory infections, especially in children.

  • 2

    hMPV exhibits genetic similarities to respiratory syncytial virus and has one serotype with two major subgroups and five sublineages.

  • 3

    Reinfections with hMPV occur throughout life due to incomplete immunity, with increased severity in adults and those with comorbidities.

  • 4

    Recent studies highlight the need for vaccines against hMPV, especially following the success of RSV vaccines in adults.

  • 5

    hMPV infections can lead to severe outcomes, including pneumonia and hospitalization, particularly in immunocompromised individuals.
