The Centre for Health Protection (CHP) of the Department of Health today (June 14) called on the public to maintain strict personal and environmental hygiene to prevent upper respiratory tract infection (URI).
The appeal followed the CHP's investigation into a URI outbreak in a kindergarten cum child care centre in Kwun Tong involving 20 students aged between two and five.Investigation revealed that the affected students, comprising 13 males and seven females, developed URI symptoms including fever, cough, sore throat and runny nose since May 27. One of them required hospitalisation and has already been discharged on June 4. All the affected students are in stable condition.
Nasopharyngeal aspirate specimen from the admitted student tested positive for adenovirus.
Staff of the CHP had conducted site visit and provided health advice to the school. The kindergarten cum child care centre was put under medical surveillance.
A CHP spokesman said adenovirus was a group of virus that commonly cause viral infection in children. The symptoms may vary from respiratory symptoms such as fever, cough, runny nose and sore throat, to gastroenteritis illnesses such as vomiting and diarrhoea. It may also cause conjunctivitis.
"Adenovirus infection is usually transmitted by direct contact or faecal-oral transmission. It can occur throughout the year," the spokesman said.
Most infections are mild and patients usually require no therapy or only symptomatic treatment. Strict attention to good hygiene practices is effective for preventing adenovirus-associated diseases.
To prevent URI and influenza, the public are advised to adopt the following measures:
* Build up good body immunity by having a proper diet, regular exercise and adequate rest, reducing stress and avoiding smoking;
* Maintain good personal and environmental hygiene, and wash hands after sneezing, coughing and cleaning nose. Wear a mask when developing symptoms of respiratory infections;
* Maintain good ventilation; and
* Avoid visiting crowded places with poor ventilation, especially during peak influenza season.
Members of the public, particularly children, elderly people and those with chronic diseases, should wear face masks and consult their doctors for medical advice promptly if they develop symptoms of respiratory tract infection.
