Multicenter Cross-sectional Study on the Epidemiology of Human Metapneumovirus in Italy, 2022-2024, With a Focus on Adults Over 50 Years of Age.

ABSTRACT:

Background

Human metapneumovirus (hMPV) infections have a significant impact on public health. However, the extent of this burden in Italy remains poorly defined due to a lack of comprehensive data. The aim of this cross-sectional multicenter study was to understand the epidemiology of hMPV in Italy, particularly in older adults.

Methods

We analyzed laboratory data from molecular respiratory viral diagnostic tests conducted at 17 centers across Italy from September 2022 to August 2024. Respiratory viruses were tested from outpatients for epidemiologic surveillance and from patients presenting to tertiary hospitals for diagnostic purpose. G gene sequencing was performed on a limited number of circulating strains.

Results

Data from 96 460 tests yielded an overall hMPV p
