Press Release

Latest update on surveillance data in winter influenza season

18 April 2015

The Centre for Health Protection (CHP) of the Department of Health today (April 18) 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 (April 17) to noon today, no additional cases of influenza-associated admissions to an intensive care unit or death 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 the total therefore remains at 632, including 487 deaths so far. Among them, 589 were A(H3N2), eight were A(H1N1)pdm09, six were A pending subtype and 29 were B. In the last winter season in early 2014, 266 cases (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 18 (one death) and all were A(H3N2). In 2014, 27 cases (four deaths) were filed.

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