test. Among 49 suspected cases, 33 were probable. Attack rate was
1.2%. Three cases had a positive culture for Salmonella typhi and
were not drug resistant. The following risk factors were identified:
drinking unboiled river water (adjusted OR 12.5, 95%CI 2.8-75.3),
history of contact with other patients before the illness (adjusted OR
22, 95%CI 3.5-76.2), no hand washing with soap after defecation
(adjusted OR 0.15, 95% CI 0.03-0.81). Environmental investigation
result showed that most of the households had unsanitary latrine and
some latrines were constructed near the edge of a river. The outbreak
subsided quickly after intervention. ISSN: 0125-2208.

brevirostiris are found in coastal waters from the Bay of Bengal east to
Palawan, Philippines and south to northern Australia. They also occur
in three large tropical river systems in South-east Asia: the Mekong,
Mahakam and Ayeyarwady. In March and May 1997 approximately 350
km of riverine habitat in parts of north-east Cambodia were surveyed,
discussions took place with local people, and reported dry season
dolphin habitat was mapped. Our objectives were to investigate the
status, habitat and distribution of dolphins in north-east Cambodia and
identify threats to the continued survival of dolphins in the Mekong
River Basin. Nine groups of dolphins were observed in the Mekong
River. A 'best' estimate of 40 animals were seen. Irrawaddy dolphins
were generally confined to sections of the river with water levels >8-
10 m during the dry season. It appears that the Mekong River dolphin
