The Centre for Health Protection (CHP) of the Department of Health is today (February 1) investigating an outbreak of upper respiratory tract infection (URTI) at a secondary school in Wong Chuk Hang, and appeals to members of the public and staff of institutions to maintain strict personal and environmental hygiene, and receive seasonal influenza vaccination for better protection.

     The outbreak involves 55 students, comprising 42 males and 13 females aged 12 to 20. Most of the affected persons are Secondary Six students. Eleven staff members are also involved. They have developed symptoms since January 27. Twelve of them sought medical attention. All are in stable condition and none required hospitalisation.

     The officers of the CHP have visited the secondary school and provided preventive advice against URTI, such as advising the school to arrange cleaning and disinfection, to open windows where appropriate for better ventilation, to separate affected students from other students, etc. The school has been placed under medical surveillance.

     The public should maintain good personal and environmental hygiene against influenza and other respiratory illnesses and note the following:
 

• Receive seasonal influenza vaccination for personal protection;
• Surgical masks can prevent transmission of respiratory viruses from ill persons. It is essential for persons who are symptomatic (even if having mild symptoms) to wear a surgical mask;
• For high-risk persons (e.g. persons with underlying medical conditions or persons who are immunocompromised), wear a surgical mask when taking public transport or staying in crowded places. It is important to wear a mask properly, including performing hand hygiene before wearing and after removing a mask;
• Avoid touching one's eyes, mouth and nose;
• Wash hands with liquid soap and water properly whenever possibly contaminated;
• When hands are not visibly soiled, clean them with 70 to 80 per cent alcohol-based handrub;
• Cover the nose and mouth with tissue paper when sneezing or coughing. Dispose of soiled tissue paper properly into a lidded rubbish bin, and wash hands thoroughly afterwards;
• Maintain good indoor ventilation;
• When having respiratory symptoms, wear a surgical mask, refrain from work or attending classes at school, avoid going to crowded places and seek medical advice promptly; and
• Maintain a balanced diet, exercise regularly, take adequate rest, do not smoke and avoid overstress.

     ​​​Members of the public, particularly children, the elderly and those with chronic diseases, should consult a doctor promptly if they develop symptoms of respiratory tract infection.
