A Case of Dengue Hemorrhagic Fever in a Japanese Child

Abstract

A 6-year-old Japanese girl contracted a febrile illness with hemorrhagic manifestations when she traveled in Indonesia. A remarkable decrease in the numbers of platelets and white blood cells was observed in her acute-phase blood specimens. Her father, who accompanied her, showed dengue fever-like symptoms at almost the same time as her illness. It was determined by serological tests that they were infected with dengue virus type l. Moreover, she showed a secondary antibody response to the flavivirus due to the pre-existing antibody to Japanese encephalitis virus. This is the first confirmed case of dengue hemorrhagic fever (DHF) in Japanese people. © 1989, Center For Academic Publications Japan. All rights reserved.
