Epidemiology and aetiology of acute childhood diarrhoea in Burma: a rural community survey.

Identical epidemiological and microbiological surveys were carried out in a rural community at Intakaw, Burma, in 2 months, one in the hot wet and the other in the cool dry season. The incidence of diarrhoea was highest in children under 3 years old and in the hot wet month when enterotoxigenic Escherichia coli was the predominant pathogen. Rotavirus was the commonest pathogen in the cool dry month but was absent in the hot wet month.

Isolation of dengue type 3 from mosquitoes in Rangoon.

A virus was isolated in suckling mice from Aedes aegypti collected from Rangoon area, during the month of July 1969. The virus was identified as a member of Group B arbovirus dengue type 3, by means of its ability to agglutinate goose erythrocyte at pH 6.6, haemagglutination inhibition and complement fixation tests, and its growth characteristics in Aedes albopictus cell cultures.
