Abstract

To explore Bangladesh's ability to detect novel influenza, we examined a series of laboratory-confirmed pandemic (H1N1) 2009 cases. During June-July 2009, event-based surveillance identified 30 case-patients (57% travelers); starting July 29, sentinel sites identified 252 case-patients (1% travelers). Surveillance facilitated response weeks before the spread of pandemic (H1N1) 2009 infection to the general population.

Location of 12 sentinel-site surveillance hospitals (red crosses) and of persons confirmed as infected with pandemic (H1N1) 2009 virus during June 2009–October 2010, Bangladesh. Open circles indicate case-patients identified during 2009; solid circles indicate case-patients identified during 2010. Testing was conducted on the basis of cases of severe pneumonia in hospitalized case-patients (<5 years of age), severe acute respiratory infection in hospitalized case-patients (>5 years of age), influenza-like illness, and acute respiratory infection in ambulatory case-patients (all age groups) identified as part of event-based, sentinel-site, and community-based surveillance systems.
