Abstract Influenza viruses are highly capable of mutating and adapting in mammalian hosts . While these viruses have been extensively studied in birds, research on their presence in bats has been limited. However, influenza viruses circulating in bats have shown notable molecular divergence . The present study aimed to characterize the phylogenetic, evolutionary, and antigenic relationships of an influenza A virus detected in the fishing bat Noctilio albiventris . As part of a pathogen surveillance study of public health interest, 159 rectal samples were collected from bats in the Colombian Caribbean . The samples were sequenced using RNA-Seq. A genome (eight viral contigs) associated with the Orthomyxoviridae family was identified in a pool. Most segments showed approximately 90% similarity with H18N11, except for the neuraminidase. Analysis of the N protein shows that occupies a basal position relative to the N11 subtype, with its divergence date estimated to be approximately 50 year...

{Summary} 1 Introduction The COVID-19 pandemic underscored the urgency of ensuring that the world is prepared for the next major respiratory pathogen pandemic (1). Corresponding with World Health Assembly resolutions WHA58 .5 (2) and WHA74.7 (3), WHO is committed to supporting Member States with pandemic preparedness planning through the provision of guidance and technical assistance . Following on from the PRET Global Meeting in April 2023, WHO has finalized guidance on Preparedness and resilience for emerging threats (PRET) module (1): planning for respiratory pathogen pandemics. This module acknowledges that similar systems and capacities can be used to prevent, prepare for and respond to different respiratory pathogens. The module (4) has three overarching objectives: - to guide countries and partners in developing or updating their integrated approach to respiratory pathogen pandemic preparedness for equitable and robust response; - to focus attention on the actions needed to stre...
