The Centre for Health Protection (CHP) of the Department of Health today (December 4) urged members of the public and management of institutions to take preventive measures against influenza-like illness (ILI) by strictly observing rules about environmental and personal hygiene.
The appeal was made following CHP's investigation into a report of parainfluenza outbreak in a school in Tuen Mun, affecting 14 students and six staff members.
The affected group comprised 13 males and seven females, aged between 7 and 36.
They developed ILI symptoms including fever, cough, runny nose and sore throat between November 22 and today. All the affected are in stable condition. The investigation continues.
The nasopharyngeal aspirate specimen taken from an affected student was tested positive for parainfluenza virus.
CHP officials have conducted a field visit to the school and provided health advice to the staff.
To prevent respiratory tract infection, people 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;
* Wash hands after sneezing or coughing, and wear a mask when having symptoms of respiratory tract infection;
* Maintain good ventilation; and
* Avoid visiting crowded places with poor ventilation.
Members of the public, particularly children, elderly people and those with chronic diseases, should wear face masks and consult doctors promptly if they develop symptoms of respiratory tract infection.
