26 March 2015

The Centre for Health Protection (CHP) of the Department of Health today (March 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 (March 25) to noon today, four additional cases of influenza-associated admission to intensive care units or death, including three 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, bringing the total to 569 (427 deaths) so far. Among them, 536 were A(H3N2), eight were A(H1N1)pdm09, eight were A pending subtype and 17 were B. In the last winter season in early 2014, 266 cases (133 deaths) were filed.

Last week (from March 15 to 21), 38 cases (25 deaths) were recorded. Separately, a daily average of 5.1 cases (3.1 deaths) were filed in the last seven days (from March 19 to 25), compared with 5.7 cases (4.6 deaths) in the preceding seven days (from March 12 to 18).

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

Turning to influenza-like illness (ILI), an institutional outbreak affecting 11 persons was reported to the CHP yesterday (March 25) by a primary school.

The public should maintain good personal and environmental hygiene against influenza and other respiratory illnesses:
