Ministry Of Health Investigating a Cluster Of Cholera Cases At Bedok

15 Oct 2004

            A cluster of eight local cholera cases has been identified in Singapore, comprising two males and six females aged between 20 to 84 years. The cases had acute onset of illness between 3 and 10 Oct 2004 and were admitted to SGH, CGH and CDC. Three have been discharged and the other five are recovering.

3          Investigations by the Ministry revealed that majority had patronised hawker stalls and eating establishments in Bedok.  A total of 115 food handlers and 25 home contacts have been referred to CDC for medical screening. Food samples and environmental samples from the food outlets have also been sent for laboratory analysis.

4          Cholera is an acute disease caused by ingestion of food or water contaminated with the bacterium, Vibrio cholerae. Only rarely is cholera spread by person to person contact. Symptoms include acute painless watery diarrhoea and vomiting, which can result in dehydration if not properly treated. Because the bacterium is found in the aquatic environment, common vehicles of transmission include fish and shellfish. 

5          The Ministry of Health is currently working closely with NEA.  The implicated establishments have been inspected and found to be satisfactorily maintained. Investigations to trace the source of infection are in progress.

6          The public is advised to:

• Eat only foods that have been thoroughly cooked

• Avoid consuming undercooked raw fish or shellfish

• Maintain proper personal and food hygiene at all times

• See a doctor promptly if you have symptoms of diarrhoea or vomiting.
