Infectious Disease Surveillance

Infectious disease surveillance is the systematic collection and analysis of health data to monitor and control diseases that can spread from person to person. This process helps identify outbreaks, track disease trends, and evaluate the effectiveness of prevention strategies. Public health officials use surveillance to inform responses, allocate resources, and protect communities from outbreaks like influenza or COVID-19. By keeping a close watch on the spread of infections, surveillance plays a crucial role in promoting public health and ensuring timely interventions to reduce the impact of infectious diseases.
