A 67-year-old woman died on Monday after being hospitalised with type A flu for three weeks, raising the number of flu-linked casualties this winter to 13.
According to the health ministry, the woman faced underlying chronic health problems.
The ministry said that since February 1 flu incidents remain high, with eight people still being treated on Monday though a steady decline has been recorded in the past four weeks, especially among children.
Since December 1, general hospitals around the island have dealt with a total of 58 serious cases of flu, most of which have been treated and the patients discharged.
The health ministry reiterated that the best defence against the virus is the relevant vaccine, which is mainly available for vulnerable groups.
It also urged the public to take preventive measures such as avoiding crowded spaces, using handkerchiefs when sneezing, washing hands often, avoiding smoking, and keeping children at home for at least 48 hours after flu symptoms subside.
