Case of severe paediatric influenza A infection under CHP investigation

19 February 2015

The Centre for Health Protection (CHP) of the Department of Health is today (February 19) investigating a case of severe paediatric influenza A infection affecting a one-year-old girl.

The patient, with good past health, has presented with fever and convulsion since February 17. She was brought to the Accident and Emergency Department of Tseung Kwan O Hospital on February 18 and was admitted on the same day. Her condition deteriorated and was subsequently transferred to the Paediatric Intensive Care Unit of United Christian Hospital (UCH) for further management today. The clinical diagnosis was encephalopathy. She is currently in critical condition.

Her tracheal aspirate tested positive for influenza A (H3) upon laboratory testing by UCH.

Initial enquiries by CHP revealed that the patient had no travel history during the incubation period. Her home contacts remained asymptomatic.

Investigation is ongoing.

The public should maintain good personal and environmental hygiene 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;
• 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;
• When influenza is prevalent, 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.
