Emerging viral infections pose a continual threat to human health, encompassing a spectrum of diseases from mild to severe, and sometimes fatal, outcomes. These infections arise from newly identified or (re-)emerging viruses, often crossing species barriers to infect humans.
Such infections not only challenge public health systems but also strain social and economic resources globally. Recent outbreaks, exemplified by Zika virus, Ebola virus, and the severe acute respiratory syndrome coronavirus 2 pandemic, underscore the urgent need for robust preparedness and response strategies to mitigate their impact. As these viruses continue to evolve and adapt, understanding their mechanisms of transmission, pathogenesis, and immune evasion becomes paramount in safeguarding human health and preventing future pandemics.
