Work out sentinel surveillance coverage instantly with clear inputs, formula shown and shareable results.
Reports what share of facilities and population a sentinel surveillance network covers, and how many sites full coverage would need.
Surveillance coverage
Population coverage (%) = population in sentinel catchments / total population x 100; facility coverage = sentinel sites / total facilities x 100
It needs to be consistent over time for trend detection; representativeness matters more for estimating burden.
Sentinel sites allow higher data quality and laboratory confirmation at affordable cost.
