Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data to monitor the spread of diseases within populations. Its primary goal is to detect outbreaks early, track disease trends, and inform public health decisions. By keeping an eye on illness patterns, health authorities can respond more effectively, implement prevention strategies, and allocate resources where needed. Surveillance helps identify high-risk areas and populations, ensuring timely interventions to protect community health. It plays a crucial role in managing both infectious diseases, like flu or COVID-19, and non-communicable diseases, like diabetes or cancer.
