Public Health Surveillance

According to the World Health Organization (WHO), public health surveillance (also known as epidemiological surveillance, clinical surveillance, or syndromic surveillance) is "the continuous, systematic collection, analysis, and interpretation of health-related data needed for the planning, implementation, and evaluation of public health practise." A timely search for effective solutions to developing health-related problems can be made possible by public health surveillance. In most cases, surveillance systems are asked to give details on when, when, and who is affected by health issues. Both passive and active public health surveillance methods are available. All healthcare establishments in a specific region are required to report illnesses and symptoms on a regular basis as part of a passive surveillance system.
