Post-Pandemic Dynamics of the Global Circulation of Human Metapneumovirus and Respiratory Syncytial Virus.

ABSTRACT:

Background

Understanding the seasonality of human metapneumovirus (hMPV) and respiratory syncytial virus (RSV) is important for public health planning. It can support rationale for using another country data to model immunization strategies where seasonality data are lacking. While some studies have investigated (sub)-national seasonality drivers, this is the first to describe global seasonality for RSV and hMPV.

Methods

We included 26 countries with consistent reporting and >10 detections at the peak, after searching international databases and local reports. Weekly surveillance data from January 2022 to June 2024 were included. Viral activity was defined by comparing the 4-week moving average of the positivity rate to its annual average. "Seeding" events were the first 2 c
