Clinical differences between influenza A (H1N1) pdm09 & influenza B infections identified through active community surveillance in North India.

ABSTRACT:

Background & objectives

Most studies on the clinical presentation with influenza viruses have been conducted in outpatient or inpatient medical facilities with only a few studies in community settings. Clinical differences between influenza A (H1N1) pdm 09 and influenza B virus infections have importance for community-based public health surveillance. An active community surveillance at the time of emergence of pandemic influenza provided us with an opportunity to compare the clinical features among patients infected with influenza A (H1N1) pdm09 virus and those with influenza B virus co-circulating in an active community-based weekly surveillance in three villages in Faridabad, Haryana, north India.

Methods

Active surveillance for febrile acute respiratory infection (FARI)
