A two-year-old girl has been admitted to an intensive care unit with a severe case of influenza A.

The girl, who previously had a record of good health, was admitted to Hong Kong Adventist Hospital in Tsuen Wan in the New Territories on March 31. Medical staff were told the child had had a fever, cough, runny nose and had been vomiting since March 14.

On Wednesday, the girl was transferred to a paediatric intensive care unit at Princess Margaret Hospital for closer management, according to a government release. She is now in serious condition.

The girl’s clinical diagnosis was influenza A complicated with severe pneumonia.

The girl did not receive an influenza vaccination for the current season and had no history of travel in the incubation period, according to an initial investigation by the Centre for Health Protection.

The domestic worker who takes care of her had symptoms of an upper respiratory tract infection recently, but other family members showed no symptoms.

Meanwhile, the Center announced that the winter flu season formally ended on March 31. Some 570 adults were recorded as being admitted to intensive care units with flu symptoms and 382 of them died.

For children aged under 18, there were 20 severe cases but just two deaths recorded among them. 95% of the severe child patients did not receive influenza vaccinations for the current season.
