Via the Centre for Health Protection: Update of surveillance data in winter influenza season. Excerpt:
Regarding severe cases, from noon yesterday (February 10) to noon today, 11 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. This brings the total number to 247 (164 deaths) so far this year.
Apart from the six deaths among newly reported cases, there was one additional death in the past 24 hours among previously reported cases requiring intensive care unit admission. Among them, 232 were A(H3N2), six were B and nine were A pending subtype. In the last winter season in early 2014, 266 (133 deaths) were filed.
Of note, in the 247 cases and 164 deaths above, 209 cases (84.6 per cent) and 152 deaths (92.7 per cent) involved elderly persons aged 65 or above. Senior citizens yet to be vaccinated should do so promptly as vaccination can reduce disease severity, hospitalisations and deaths, particularly for high-risk groups.
Furthermore, no additional cases of severe paediatric influenza-associated complication among children aged under 18 have been reported since yesterday via the ongoing reporting system. The total number this year hence remains at 11 (no deaths) and all were A(H3N2). In 2014, 27 (four deaths) were filed.
Among respiratory specimens received by the CHP's Public Health Laboratory Services Branch, the percentage that tested positive for influenza viruses was 34.4 per cent in the week ending February 7. Over 95 per cent of influenza virus detections were A(H3N2).
