Another patient has died after flu exacerbated her underlying health problems, raising the number of flu-linked deaths to 17, the health ministry said on Friday.
The woman, who was being treated in a state hospital, was in the high-risk group for serious diseases.
Four other serious cases are in intensive care units of state hospitals, but there has been no new admission of a serious case over the last 48 hours, the ministry said.
In total, 59 patients with serious symptoms have been recorded since December 1, most of whom have been discharged. Some of them are being treated in state hospitals.
Although influenza activity has declined significantly over the past few weeks, the virus is still active. The flu season is expected to last at least until the end of March.
The health ministry reiterated that the flu vaccine remains the best way to prevent the disease, especially for vulnerable groups.
