A dengue shock patient with negative serology and polymerase chain reaction (PCR) tests.


A 6-month-old Thai girl presented with clinical manifestations of dengue shock syndrome (DSS) with encephalopathy and urinary tract infection. Serology and PCR tests were negative whereas dengue virus type 2 was isolated. In cases of highly suspected dengue infections, viral isolation should be done even when serological and PCR tests are negative.
