Latest update of surveillance data in winter influenza season

26 February 2015

The Centre for Health Protection (CHP) of the Department of Health today (February 26) reported the latest surveillance data of the winter influenza season, and again urged the public to heighten vigilance and get vaccinated early against seasonal influenza.

Regarding severe cases, from noon yesterday (February 25) to noon today, eight additional cases of influenza-associated admission to intensive care units or death (including six deaths) among adults aged 18 or above have been recorded under the enhanced surveillance in collaboration with public and private hospitals reactivated since January 2, bringing the total to 391 (289 deaths) so far. Among them, 376 were A(H3N2), one was A(H1N1)pdm09, five were A pending subtype and nine were B. In the last winter season in early 2014, 266 (133 deaths) were filed.

Meanwhile, no additional cases of severe paediatric influenza-associated complication or death among children aged under 18 have been reported since yesterday via the ongoing reporting system and the total this year hence remains at 17 (one death) and 16 were A(H3N2) while one was A pending subtype. In 2014, 27 cases (four deaths) were filed.

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.
