No excuse for Hongkongers at risk not to get flu jab
- With Covid-19 seemingly under control, Hong Kong has to ensure it now guards against rising influenza cases
Weeks have passed since the mask mandate was lifted, and thankfully Covid-19 remains under control. Separately, fears of complications arising from seasonal influenza infections have so far not materialised.
Optimistic as it seems, the public must continue to remain alert. The announcement that the city has entered the influenza season ought to heighten vigilance.
According to the latest surveillance data of the Centre for Health Protection, the weekly percentage of detections tested positive for seasonal flu viruses has increased from below 1 per cent in the first week of March to 9.89 per cent in the week ending April 1.
The majority of cases were classified as influenza A (H1), with children and adults, aged from 50 to 64, affected most in seasons dominated by the virus, according to records.
Adding to concern is a growing admission rate to hospitals, up from 0.01 to 0.25 per 10,000 of the population during the period.
Weekly reports of outbreaks linked to institutions received by health authorities also recently rose from one to two cases to 12. They covered primary and secondary schools, special schools, residential care homes for the disabled and elderly as well as hospitals.

As experts have repeatedly warned, immunity against flu in the community may be relatively weaker than in the past because of the low levels of infection during the coronavirus pandemic. Necessary precautions, such as vaccinations against seasonal flu, must therefore be strengthened.
Vulnerable groups, including children, the elderly and chronically ill should follow the advice. The growing number of travellers would also be wise to have their jabs and to remain alert to the health situation in the places they go.
About 1.53 million doses of flu vaccine have already been administered, covering 47 per cent of those aged 65 or above and 40 per cent of groups aged six months up to the age of 18. But there is certainly room to do more.
The public must guard against a false sense of security arising from the stabilising pandemic. Indeed, data has shown a slight increase in reported Covid infections and in the viral load of sewage.
Vigilance and a cautious approach must prevail if the city is to get through the flu season safely.
