More than 320 people have been killed by seasonal influenza so far this year in Hong Kong, according to data from the regional Centre for Health Protection (CHP) under the Department of Health. A total of 456 severe flu cases have also been recorded, most of which are H3N2 bird flu virus (H3).

Since the activation of enhanced surveillance for severe infection on May 5, 2017, 19 cases (including three deaths) involved severe pediatric influenza-associated complications. Initial enquiries found that most patients had yet to receive seasonal influenza vaccinations.

The CHP defined seasonal influenza as an acute illness of the respiratory tract caused by influenza viruses. It is usually more common in the periods from January to March and from July to August in Hong Kong. Currently, there are two subtypes of seasonal influenza A viruses circulating in humans – namely influenza A (H1N1) pdm09 and influenza A (H3N2), according to CHP's report.

After investigation, the CHP said there are many causes that contribute to the serious situation this year, including Hong Kong’s rising population of elderly people more susceptible and less resistant to the viruses.

A spokesman from the CHP said, "The local seasonal influenza activity remains at a high level and it is expected to remain active in the coming weeks. We strongly urge the public, particularly children, and the elderly and chronic disease patients, to adopt strict personal, hand and environmental hygiene both locally and during travel in the summer."
