Infectious Disease Surveillance is the systematic collection, analysis, and interpretation of data related to infectious diseases. This process helps public health officials monitor disease outbreaks, track the spread of infections, and identify trends over time. By gathering information from hospitals, laboratories, and other sources, health authorities can respond quickly to emerging threats. Effective surveillance relies on various methods, including laboratory testing, epidemiological studies, and reporting systems. These tools enable health organizations to implement control measures, allocate resources, and inform the public about potential risks. Ultimately, surveillance plays a crucial role in protecting communities from infectious diseases.
