In June 2006, 118 Singaporean soldiers visited Brunei for jungle training for 10 days. Subsequently, two soldiers had severe @entity294 and were diagnosed with severe @entity5293 . An epidemiological investigation and case-control study was conducted among the 118 soldiers. A survey was administered to determine the exposures predisposing to @entity281 . Laboratory tests included a full blood count and three separate faecal screens via microscopy and culture. All servicemen were treated with one dose of @entity7400 , and follow-up screening was performed 3 months later. Of 113 soldiers completing the questionnaire, 43 soldiers (38%) reported gastrointestinal symptoms post deployment, with 33 (29%) complaining of @entity294 and 29 (26%) of @entity490 . Eight had an itch or @entity1910 , but none were suggestive of @entity10629 . Of 103 soldiers completing both the questionnaire and with all the laboratory tests, 42 soldiers (41%) had @entity1712 (>0.6x10(9)/l) and 18 (17%) had @entity5293 on microscopy. More than 89% recalled substantial exposure to soil or groundwater, but no exposure was significantly associated with @entity1712 or @entity281 . After adjusting for possible exposures, not wearing footwear during rest periods had a significantly higher odds ratio (2.86) for acquiring @entity5293 or @entity1712 . @entity281 are common in visitors to rural Asia. As preventing exposure is often difficult, empirical treatment with anthelminthics should be considered in travellers to high risk areas.
