A sentinel surveillance site is a single or small number of health facilities that are responsible for collecting data on cases enrolled with the case definition under surveillance including global networks surveying for diarrhea or pneumonia. Sentinel site surveillance provides useful epidemiological information on proportions caused by different pathogens, age distribution, and risk factors and could also be used for monitoring trends of hospitalized cases within a health facility if health-care patterns and population have been stable. In contrast, with population-based surveillance, every appropriate health facility reports on the predefined diseases with the goal of identifying all cases in a specific geographic area.	./cache/cord-304455-z5n9ys86.txt	./txt/cord-304455-z5n9ys86.txt
