Abstract
INTRODUCTION: Hulu Langat District Health Office was notified of students presented with acute gastroenteritis symptoms from three different institutions on 28th February 2019. All the affected students went to the same motivational camp in Sungai Congkak on the 22nd-25th February 2019. A study was conducted to describe the outbreak, identify risk factors, and implement control measures. METHODS: Case control study was used. Case was defined as any individual who attended the camp on the 22nd-25th February 2019, presented with either nausea, vomiting, diarrhea, or abdominal pain from 23rd February 2019. Active case detection was conducted, and students were interviewed. Hazard analysis and critical control points (HACCP) and environmental investigations were done. RESULTS: Attack rate was 30.8% (124/403), 116 cases (93.5%) did not seek for any medical attention, and another eight cases (6.5%) was treated as outpatient. Main symptoms were abdominal pain (64.52%), diarrhoea (58.06%) and vomiting (47.58%). Food premise rating was 70.1%. The investigation found that the usage of untreated water in several process without sanitation process caused cross contamination. The laboratory result showed isolation of Coliform Sp. from two environmental swabs, and isolation of Coliform Sp and E. Coli from five different water samples from the Gravity Feed System (GFS) supported the analysis. CONCLUSIONS: The outbreak was most likely due to usage of untreated contaminated water from the GFS as the only source of water at the camp, and the suspected bacteria is E. Coli Health education was given on safe water practices and basic sanitation to the camp owner and food handlers.
