Emerging infectious diseases (EIDs) represent a dynamic and evolving threat to global public health. These diseases, which are newly identified or reemerging with increased incidence or geographic range, pose significant challenges to healthcare systems and society at large. Factors such as population growth, urbanization, international travel, and climate change contribute to the emergence and spread of EIDs. The rapid globalization of trade and travel further facilitates the dissemination of infectious agents across borders, amplifying the risk of pandemics. Recent examples of EIDs include the Zika virus, Ebola virus disease, and COVID-19, each highlighting the potential for previously unknown pathogens to cause widespread illness and societal disruption. Addressing the complex drivers of EIDs requires a multifaceted approach, encompassing surveillance, early detection, rapid response, vaccination, antimicrobial stewardship, and international collaboration to mitigate their impact on human health and well-being.
