Advancements in Disease Surveillance: The Role of GIS in Global Health Preparedness

Abstract

This article explores the application of Geographic Information Systems (GIS) in disease surveillance, a critical tool for managing emerging health threats in the 21st century. By enabling real-time monitoring, spatial analysis, and data integration, GIS has become essential for tracking disease outbreaks, optimizing healthcare resources, and informing public health interventions. The article highlights how GIS technology enhances preparedness and response during crises, with a particular emphasis on the COVID-19 pandemic, where GIS facilitated rapid data dissemination and visualization. Moreover, the integration of artificial intelligence and data analytics with GIS systems promises to advance predictive capabilities, improve decision-making, and foster global collaboration. Despite its transformative impact, challenges such as data quality, ethical considerations, and infrastructure limitations are noted. Addressing these obstacles through stakeholder engagement and equitable access is crucial for maximizing GIS’s potential to build resilient health systems capable of confronting future public health crises.
