    The study analyzed 3620 hospitalized adults with influenza-like illness, identifying infections from hMPV, FLUV, and RSV.

  • 2

    Human metapneumovirus (hMPV) was detected in 5% of patients, while influenza viruses accounted for 42% and respiratory syncytial virus for 7%.

  • 3

    Patients with hMPV were more likely to develop complications, particularly acute heart failure, compared to those with influenza.

  • 4

    The in-hospital death rate was similar across hMPV, FLUV, and RSV groups, ranging from 4% to 5%.

  • 5

    Hospitalized hMPV infections predominantly affected older adults with chronic conditions, leading to frequent cardiac and pulmonary complications.
