CHP investigates outbreak of acute gastroenteritis at kindergarten in Wan Chai
******************************************************************************
The outbreak involves 22 students (comprising 11 boys and 11 girls aged 4 to 6) and two staff members. They developed vomiting and diarrhoea since May 16. Seventeen of them sought medical attention, one of whom required hospitalisation and has been discharged after management. All patients are in stable condition.
According to the CHP's epidemiological investigation, two of the students in the outbreak had vomited in public area of the school, revealing that the outbreak has a higher chance of person-to-person transmission or environmental contamination, while the chance of involving food poisoning is relatively low.
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 reminded that alcohol-based handrub should not substitute hand hygiene with liquid soap and water, as alcohol does not effectively kill some viruses frequently causing AGE e.g. norovirus. Members of the public are advised 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.
The public may visit the CHP's website (www.chp.gov.hk) or call the DH's Health Education Infoline (2833 0111) for more information.
