CHP investigates outbreak of acute gastroenteritis in kindergarten

22 April 2015

The Centre for Health Protection (CHP) of the Department of Health (DH) is today (April 22) investigating an outbreak of acute gastroenteritis (AGE) in a kindergarten in Tuen Mun affecting 22 pupils, and hence appealed to the public and management of institutions to maintain personal and environmental hygiene against AGE.

The affected pupils, 11 boys and 11 girls aged from 4 to 6, have presented with vomiting and diarrhoea since April 20. 12 of them sought medical attention and none required hospitalisation. They are now in stable condition.

Investigations are continuing.

Officers of the CHP have conducted a site visit and provided health advice to the staff of the kindergarten concerning proper disinfection, disposal of vomitus, and personal and environmental hygiene. The kindergarten has been put under medical surveillance.

A spokesman for the CHP advised members of the public to take heed of the following preventive measures against AGE:

• Ensure proper personal hygiene;
• Wash hands thoroughly before handling food and eating, and after using the toilet;
• Wear gloves when disposing of vomitus or faecal matter, and wash hands afterwards;
• Clean and disinfect contaminated areas or items promptly and thoroughly with diluted household bleach (by adding one part of bleach containing 5.25 per cent sodium hypochlorite to 49 parts of water);
• Maintain good indoor ventilation;
• Pay attention to food hygiene;
• Use separate utensils to handle raw and cooked food;
• Avoid food that is not thoroughly cooked;
• Do not try to use salt, vinegar, wine and wasabi to kill bacteria as they are not effective;
• Drink boiled water; and
• Do not patronise unlicensed food premises and food stalls.
