Infectious diseases remain the commonest health problem with high prevalence and burden resulting in huge social, economic and quality of life losses globally. Surveillance on infectious diseases is an epidemiological practice through systematic collection, analysis, and interpretation of data that provides real time notification to decision makers on health problems. The main role of disease surveillance is to predict, observe, and minimize the harm caused by outbreak, epidemic, and pandemic situations, as well as increase knowledge about which factors contribute to such circumstances. A key part of modern disease surveillance is the practice of disease case reporting. With the advent of modern communication technology, this has changed dramatically. There are different types of strategies to meet the surveillance. 1) Sentinel surveillance systems consist of health facilities or laboratories in selected locations that report all cases of a certain condition to indicate trends in the entire population. Sample reporting is a good way to use limited resources to monitor suspected health problems. Examples include networks of health providers reporting cases of certain bacterial infections among children. 2) Household surveys can be used to monitor diseases if the surveys are consistent and repeated periodically. The surveys are population-based; that is, they select a random sample of household’s representative of the whole population. Examples include demographic and health surveys in developing countries. 3) Laboratory-based surveillance is used to detect and monitor infectious diseases. For example, for food-borne diseases such as salmonella, the use of a central laboratory to identify specific strains of bacteria allows more rapid and complete identification of disease outbreaks than a system that relies on reporting of syndromes from clinics. 4) Integrated disease surveillance and response (IDSR) strategies bring together data from health facilities and laboratories. It is a critical tool to prevent outbreaks of diseases and develop appropriate, rapid responses when diseases begin to spread.
