CHP investigates suspected outbreak of fifth disease at primary school
**********************************************************************
The 27 affected pupils, 19 boys and eight girls aged from 4 to 9, developed rash over their face, limbs and trunk from September 19 to November 14. All of them sought medical attention but required no hospitalisation. They have been in a stable condition all along.
Officers of the CHP conducted site visit and advised the school on necessary infection control measures against infections. The school has been put under medical surveillance.
"Fifth disease is a rash illness caused by parvovirus B19. It is a mild illness that occurs primarily in children. Typically a rash occurs on the face, giving a 'slapped-cheek' appearance. The rash may itch slightly, and may appear less commonly on other parts of the body such as the limbs and trunk. Low-grade fever and tiredness often precedes the appearance of rash, which usually disappears in seven to 10 days," a spokesman for the CHP said.
"If pupils or staff develop fever, respiratory symptoms or skin rash, schools should strongly advise them not to return to campus and to promptly seek medical advice. The management of schools should observe infection control precautions on campus to prevent possible transmission of diseases," the spokesman added.
Schools are reminded to follow the Guidelines on Prevention of Communicable Diseases on preventive and control measures as well as management of outbreaks, which should be reported to the CHP for prompt follow-up.
Parvovirus B19 is transmitted primarily through direct contact with infected respiratory secretions. Good personal, hand and environmental hygiene are key to preventing infections. The public and management of institutions should:
- Maintain good personal hygiene;
- Keep hands clean and wash hands with liquid soap and water properly;
- Wash hands when they are dirtied by respiratory secretions, such as after sneezing;
- Cover nose and mouth while sneezing or coughing and dispose of nasal and mouth discharge properly;
- Keep good ventilation; and
- Avoid close contact with patients of fifth disease.
