title: Clinical and laboratory studies on haemorrhagic fever in Burma, 1970-72.
abstract: This three-year serologic study of 2 060 children with a clinical diagnosis of haemorrhagic fever, who were admitted to the Children's Hospital and other hospitals in Rangoon, has shown that the etiology of the illness was multiple. Of all these patients, 347 (16.8%) had a dengue infection (96 with primary and 251 with secondary dengue infections), 510 (24.7%) had chikungunya infections, 55 (2.7%) had simultaneous chikungunya and dengue, 263 (12.8%) had influenza A infections, 62 (3.0%) had influenza B, 12 (0.6%) had measles, and there were 811 (39.4%) for whom no etiology could be established. Epidemiological and clinical features and laboratory findings are discussed. Evidence is presented for human infections with all four types of denguevirus in Rangoon.
