Seasonal Pattern and Age-Specific Detection of Eight Respiratory Viruses Causing Acute Respiratory Infection in 2024, Bangkok, Thailand.

ABSTRACT: Since the emergence of COVID-19, the epidemiological and seasonal patterns of respiratory pathogens have shifted, highlighting the need for ongoing surveillance. This study investigated the epidemiology, seasonal trends, and age-specific detection of respiratory viruses among patients with acute respiratory infections (ARIs) in Thailand from January to December 2024. Eight respiratory viruses were detected using multiplex real-time RT-PCR. Of 7853 samples, 60.8% (4777) tested positive. The most frequently detected pathogens were influenza virus (IFV, 24.8%), SARS-CoV-2 (21.5%), and human rhinovirus (HRV, 20.8%). IFV showed biannual peaks during the cold and rainy seasons, SARS-CoV-2 peaked in the warm months, and HRV circulated year-round. Respiratory syncytial virus (RSV) and human metapn
