Latest update of surveillance data in winter influenza season

     The Centre for Health Protection (CHP) of the Department of Health today (March 12) 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 (March 11) to noon today, 14 additional cases of influenza-associated admission to intensive care units or death (including eight deaths) among adults aged 18 or above had been recorded under the enhanced surveillance in collaboration with public and private hospitals reactivated since January 2 and an additional death was recorded among previously reported cases, bringing the total to 496 (370 deaths) so far. Among them, 471 were A(H3N2), six were A(H1N1)pdm09, seven were A pending subtype and 12 were B. In the last winter season in early 2014, 266 cases (133 deaths) were filed.

     Last week (from March 1 to 7), 57 cases (44 deaths) were recorded. Separately, a daily average of 6.7 cases (5.3 deaths) were filed in the last seven days (from March 5 to 11), compared with 8.3 cases (5.9 deaths) in the preceding seven days (from February 26 to March 4).

     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 remains at 18 (one death) and all were A(H3N2). In 2014, 27 cases (four deaths) were filed.

     Turning to influenza-like illness, five institutional outbreaks (affecting 17 persons) were reported to the CHP yesterday (March 11) by schools (three outbreaks, 11 persons) and residential care homes (two outbreaks, six persons).

     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.
