RESUMO
Pediatric patients with fever and haemorrhage were studied in Jakarta, Indonesia between May 1973 and January 1974. Eighty-one of 104 demonstrated unequivocable evidence of dengue with clinical findings similar to those reported associated with dengue haemorrhagic fever in Thailand. The majority of patients had extremely high antibody titers against dengue measured by both hemagglutination-inhibition and by plaque reduction neutralization tests and all four types of dengue virus were isolated. Eight of the patients died.

A biomedical survey was conducted in 10 villages in remote, high mountain valleys of Central and South Sulawesi, Indonesia to learn whether Oriental schistosomiasis was endemic and to determine the prevalences of other intestinal parasites, malaria and filariasis in those areas. Although persons with Oriental schistosomiasis were found in three villages of South Sulawesi, follow-up inquiries revealed that these had recently migrated from a known schistosomiasis area in Central Sulawesi. Other intestinal parasites diagnosed were Ascaris lumbricoides (14%), Trichuris trichiura (7%), hookworm (68%), Entamoeba histolytica (3%), Entamoeba coli (17%), and Giardia lamblia (5%). Enterobius vermicularis, Strongyloides stercoralis, Trichostrongylus sp., Physaloptera sp., Diphyllobothrium sp. heterophyid, echinostome and dicrocoelid-like termatodes, Endolimax nana and Chilomastix mesnili were detected infrequently. Malaria parasitemias due to Plasmodium falciparum, P. vivax and P. malariae were detected in 4% of the sampled populations, Malayan filariasis was diagnosed in 21% of the subjects examined.

Almost 1,500 sera from hospital-associated groups in Colombo, Sri Lanka were tested for antibodies against melioidosis, scrub typhus, influenza, and group B arboviruses. A low prevalence of antibodies was found against meliodosis and scrub typhus. Crude prevalence rates of more than 50% were encountered for antibodies against A influenza, and there was no apparent difference in rates when these were analysed according to age, sex, or ethnic background. Influenza B antibodies were more prevalent in older individuals. Antibodies against group B arboviruses were found in all groups tested, and were significantly more prevalent in older Tamils, who has estimated attack rates of more than 5% per year.
