Abstract
The disruption of natural ecosystems caused by climate change and human activity is amplifying the risk of zoonotic spillover, presenting a growing global health threat. In the past two decades, the emergence of multiple zoonotic viruses has exposed critical gaps in our ability to predict epidemic trajectories and implement effective interventions. RNA viruses, in particular, are challenging to control due to their high mutation rates and ability to adapt and evade immune defenses. To better prepare for future outbreaks, it is vital that we deepen our understanding of the factors driving viral emergence, transmission, and persistence in human populations. Specifically, deciphering the interactions between antibody-mediated immunity and viral evolution will be key. In this perspective, we explore these dynamic relationships and highlight research priorities that may guide the development of more effective strategies to mitigate the impact of emerging infectious diseases.
