Abstract

In response to recent increases in cases of pediatric encephalitis with unknown etiology in northern Vietnam, surveillance for arbovirus activity was conducted in four provinces surrounding the city of Hanoi during June 2002 and July–August 2004. A total of 20,615 mosquitoes consisting of 19 species in 1,122 pools were processed for virus isolation; virus isolates were obtained from 44 pools. (11 isolates), (15 isolates), (13 isolates), and (4 isolates) were identified by immunofluorescence assay and sequence analysis of reverse transcription–polymerase chain reaction fragments. Surprisingly, no isolates of Japanese encephalitis (JE) virus were obtained. Isolation of and is reported for the first time from Vietnam.
