Detection of chikungunya virus (CHIKV) from a patient’s serum by duplex reverse transcription-polymerase chain reaction targeting both CHIKV and dengue virus (DENV). Lane 1, patient code 09-B09; lane 2, patient code 09-B36; lane 3, positive control (DENV), lane M, 1kb DNA ladder. The expected size of CHIKV and DENV fragment was 205 and 511 bp, respectively.
