Atypical lymphocyte in dengue hemorrhagic fever: its value in diagnosis.

ABSTRACT

Simple peripheral and buffy coat smear were studied in 40 serological confirmed dengue hemorrhagic fever patients, and in other patients with viral and bacterial infections. Atypical lymphocytosis was found in majority of dengue hemorrhagic fever both associated with secondary and also in dengue fever with primary infection as compared to other infections. The time course relationship of atypical lymphocytosis, platelet and hematocrit level were discussed, concerning their value as diagnostic and prognostic criteria in dengue hemorrhagic fever.
