Abstract

Serum specimens from patients with imported dengue fever and dengue hemorrhagic fever were directly subjected to reverse transcription and polymerase chain reaction (RT-PCR) without any RNA purification. The amplified virus genome was detected within 3 hours. The results of PCR corresponded closely to the results of virus isolation using cultured mosquito cells, suggesting that direct RT-PCR procedure greatly facilitates rapid diagnosis of dengue infection. © 1994 Wiley-Liss, Inc.
