CHP investigates case of severe paediatric influenza B infection
The Centre for Health Protection (CHP) of the Department of Health is today (February 18) investigating a case of severe paediatric influenza B infection.
The case involves a two-year-old boy with underlying illness, who has presented with cough and shortness of breath since February 15. He was admitted to United Christian Hospital on February 16 and transferred to the paediatric intensive care unit for further management today.
His nasopharyngeal aspirate tested positive for influenza B virus upon laboratory testing. The clinical diagnosis was influenza B infection complicated with severe pneumonia. He is now in a serious condition.
Initial enquiries revealed that the patient had yet to receive seasonal influenza vaccination for the current season and had no recent travel history. His home contacts are asymptomatic so far. Investigations are ongoing.
The public should maintain good personal and environmental hygiene for protection against influenza and other respiratory illnesses:
• Receive seasonal influenza vaccination for personal protection;
• 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 as an effective alternative;
• Wash or clean hands frequently, especially before touching the mouth, nose or eyes, or after touching public installations such as handrails or door knobs;
• Cover the nose and mouth when sneezing or coughing, and wash hands thoroughly afterwards;
• Dispose of soiled tissue paper properly in a lidded rubbish bin;
• Put on a surgical mask when respiratory symptoms develop;
• Maintain good indoor ventilation;
• Avoid going to crowded or poorly ventilated public places; high-risk individuals may consider putting on surgical masks when staying in such places; and
• Maintain a balanced diet, exercise regularly, take adequate rest, do not smoke and avoid overstress.
