Global Surveillance and Early Warning Systems for Neglected Viruses

Global public health is still seriously threatened by neglected viruses, which are especially dangerous in low- and middle-income nations with inadequate healthcare systems. This chapter examines the geographic distribution and epidemiological trends of these viruses, highlighting the critical need for early warning systems and thorough surveillance. It looks at how these systems have changed over time and how important they are for early epidemic identification, risk assessment, and containment. We go into great detail about fundamental elements like surveillance tactics, data gathering techniques, and analytical frameworks as well as new technical advancements like artificial intelligence, machine learning, and big data analytics that are revolutionising the way we track and anticipate viral threats. Important international networks that promote cooperative responses are also highlighted in the chapter, such as the World Health Organization's activities and several national programmes. There are still many obstacles to overcome in spite of these developments, especially in the areas of finance, logistics, and moral leadership. The chapter provides illustrative case studies to demonstrate effective surveillance strategies and their beneficial effects on public health outcomes and outbreak control. In order to improve the capacity for early detection, it highlights potential future paths including predictive modelling and the creation of next-generation diagnostic instruments. Through the integration of research, technology, and policy, this chapter emphasises how important it is to improve global readiness for overlooked viral dangers.
