Abstract

Background: A suspected peripheral neuropathy outbreak was reported from Dechentsemo Central School, Thinleygang, Punakha, following which the investigation team was immediately dispatched in the field.Objective: The aim of investigation was to ascertain the cause and risk factor for the outbreak in order to implement control measures.Methods: A case control study was devised for the investigation to study about the past exposure or deficiencies in order to find out the suspected cause and risk factors.  A semi-quantitative food frequency questionnaire was administered to both cases and controls to collect information on the type of food they have consumed. The information garnered was analyzed using Chi-Square or Fischer Exact test for categorical variables and Man-Whitney U-test for quantitative variables. Results: All 17 cases were females with mean age of 13 years (SD 2.7 years). The average daily amount of thiamine intake was 0.6 mg/day for case and 0.8 mg/day for controls against the recommended daily allowance (RDA) of 1.2 mg/day. Case and control patients differed significantly with respect to fat intake (p-value = 0.02), more strongly with folate and iron intake (p-value < 0.01).Conclusion: The outbreak of peripheral neuropathy in Dechentsemo Central School appears to be linked to reduced dietary intake rich in vitamin B1 coupled with low intake of folate and iron in their diet.

Abstract

Background: A cluster of suspected shigellosis was reported from health center in Pemagatshel district to Royal Center for Disease Control on 14th May 2012. The investigation was done to determine the cause and risk factor for the outbreak so that appropriate control and prevention measures can be implemented.Methods: A descriptive study was used for the outbreak investigation. The food items and drinks served to boarding students were collected from the mess in-charge in order to assess their risk for the outbreak. The kitchen and its premises were inspected to study the likely contamination by rodents and other animals. The water and stool specimens were tested in the laboratory to identify all possible enteric pathogens.Results: 82 boarding students were affected with an overall attack rate of 28% (82/294). Diarrhea was the predominant symptom followed by abdominal pain and headache. The onset date of the cases varied between 11th and 18th May, 2012. Shigella species was isolated from stool specimens that showed resistant to amoxicillin, nalidixic acid, chloramphenicol and sulfamethoxazole. Water specimen collected from source, distribution reservoir and tap water at school were found grossly contaminated.Conclusion: The outbreak was caused by novel strain of Shigella species which was not detected earlier in Bhutan. The promotion and provision of boiled water will greatly reduce the incidence of shigellosis especially in boarding facility.
