Abstract
INTRODUCTION: On 14/02/2017, Typhoid outbreak was declared in Kampung Aur, but the source of the outbreak cant be identified. After 11 months, another Typhoid outbreak two kilometers away from the first outbreak was declared. METHODS: Epidemiological, environmental and laboratory investigations were done to collect the data. Data were entered and analysed using Microsoft Excel version 2016. RESULTS: The first outbreak affected four cases from one family while the second outbreak involved two cases from another family. All of them were Malay males with the median age of 12 (IQR 24.0) years old. Symptoms experienced were prolonged fever (100%), poor appetite (67%), lethargy (50%), bodyache (33%), abdominal pain (33%), vomiting (33%) diarrhoea (17%). The first onset of the first outbreak was on 28/01/2017 while for the second outbreak was on 9/12/2017. The cause of the first outbreak cant be identified but after proper investigations during the second outbreak, we found four asymptomatic food suppliers from Pasar Jelawat with positive Typhidot IgA. Based on the diet history, all patients had history of eating Roti Goreng which was supplied from one of the Typhoid carriers detected. All water samples taken from the cases and food handlers house were negative for Salmonella Typhi. DISCUSSION: The source of the outbreaks was from Typhoid carrier among food handlers rather than from environmental source. A detail, thorough and non-bias investigations need to be done to find the source of the outbreak. We recommend the use of food bubble chart to track the food source.
