Regarding severe cases, from noon yesterday (March 21) to noon today, three additional cases of influenza-associated admission to intensive care units or death (including one 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, bringing the total to 545 (410 deaths) so far. Among them, 514 were A(H3N2), eight were A(H1N1)pdm09, six were A pending subtype and 17 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 complications or death among children aged under 18 have been reported since yesterday via the ongoing reporting system. The total this year remains 18 (one death) and all were A(H3N2). In 2014, 27 cases (four deaths) were filed.
