Incidence and clinical features of respiratory syncytial virus infections in a population-based surveillance site in the Nile Delta Region.

Background: Most reports about respiratory syncytial virus (RSV) in developing countries rely on sentinel surveillance, from which population incidence is difficult to infer. We used the proportion of RSV infections from population-based surveillance with data from a healthcare utilization survey to produce estimates of RSV incidence in Damanhour district, Egypt.

Methods: We conducted population-based surveillance in 3 hospitals (2009-2012) and 3 outpatient clinics (2011-2012) in Damanhour district.
