We conducted influenza surveillance in 12 hospitals across Bangladesh to identify clusters of people with life threatening influenza virus infections and to characterize the diversity of circulating influenza strains. We looked for clusters of patients presenting with severe acute respiratory illness and once per month collected specimens from persons seeking care at outpatient departments with influenza like illness. Between May and December 2007, we collected 1,045 specimens; 117 (11%) were influenza positive. Among the positive samples, 46 (39%) were influenza A and 71 (61%) were influenza B. Hemagglutinin subtyping of influenza A positive specimens detected H1 and H3 but no H5 subtypes.
