CHP investigates case of severe paediatric influenza A infection
The 8-year-old boy, with good past health, has presented with fever, cough, runny nose and confusion since December 30. He attended the Accident and Emergency Department of Prince of Wales Hospital on the next day and was admitted for further management on the same day. He is now in a stable condition.
His nasopharyngeal aspirate tested positive for influenza A virus upon laboratory testing. The clinical diagnosis was influenza A infection complicated with encephalopathy.
Initial enquiries revealed that the patient had received seasonal influenza vaccination (SIV) for the current season and had travelled to Foshan, Guangdong during the incubation period. His home contacts have remained asymptomatic so far. The CHP's investigations are ongoing.
"The latest surveillance data showed that the overall influenza activity in Hong Kong continued to increase. It is anticipated that the local influenza activity will further increase and the winter influenza season will arrive soon. Members of the public should maintain good personal protection against influenza," a spokesman for the CHP said.
"Influenza can cause serious illnesses in high-risk individuals and even healthy persons. Given that influenza vaccines are safe and effective, all persons aged 6 months or above, except those with known contraindications, are recommended to receive SIV for personal protection. Eligible persons are urged to receive SIV early for protection against seasonal influenza as it takes about two weeks to develop antibodies. Vaccination among family members is key to protecting their personal and family's health."
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.
