Surveillance tools for meningitis sentinel hospital surveillance: field guide to rapidly estimate the hospital catchment population (denominator) and the annual rate of hospitalisations


The document provides information for Ministries of Health and hospital sentinel sites on why and how to determine the denominator of at-risk children <5 years of age and rate of meningitis hospitalizations for a sentinel hospital site conducting IB-VPD surveillance. Such a methodology was previously unavailable and this estimation is critical to enable interpretation of surveillance data, particularly pre- and post- vaccine introduction.
