28 September 2012
The Centre for Health Protection (CHP) of the Department of Health today (September 28) reminded members of the public and management of institutions to maintain personal and environmental hygiene to prevent gastroenteritis.
The appeal was made following the CHP's investigation into an outbreak of acute gastroenteritis at a secondary school in Shatin involving 29 students aged between 10 and 13.
The affected students, comprising nine males and 20 females, presented with symptoms of acute gastroenteritis, including vomiting and diarrhoea, since September 21.
Sixteen of them sought medical consultation. No hospitalisation was required. All the affected are in a stable condition.
The investigation is continuing.
Officers of the CHP have visited the school and provided health advice to the staff concerning proper disinfection, disposal of vomitus, and personal and environmental hygiene.
To prevent gastroenteritis, members of the public are advised to:
* Ensure proper personal hygiene;
* Wash hands thoroughly before handling food and eating, and after using the toilet;
* Wear gloves when disposing of vomitus or faeces, and wash hands afterwards;
* Clean and disinfect contaminated areas or items thoroughly with diluted household bleach (by adding one part of household bleach containing 5.25 per cent sodium hypochlorite to 49 parts of water);
* Maintain good indoor ventilation; and
* Avoid food that is not thoroughly cooked.
Members of the public can obtain more information on the prevention of gastroenteritis from the CHP's website ( www.chp.gov.hk ) or call the Central Health Education Unit hotline, 2833 0111.
