CHP investigates outbreak of acute gastroenteritis at primary school in Kowloon Tong

     The Centre for Health Protection (CHP) of the Department of Health (DH) is today (March 2) investigating an outbreak of acute gastroenteritis (AGE) at a primary school in Kowloon Tong, and hence reminded the public and management of institutions to maintain personal and environmental hygiene against AGE.

     The outbreak involves 20 boys and seven girls aged 6 to 7 years. They developed vomiting and diarrhoea since February 28. One of them sought medical attention and required hospitalisation, and has been discharged after management. All patients are in a stable condition.

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

     Investigations are ongoing.

     A spokesman for the CHP advised members of the public to take heed of the following preventive measures against gastroenteritis:
  • Ensure proper personal hygiene;
  • Wash hands thoroughly before handling food and eating, after using the toilet or after changing diapers;
  • 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). Wash hands thoroughly afterwards;
  • 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;
  • Drink boiled water; and
  • Do not patronise unlicensed food premises or food stalls.
