The Centre for Health Protection (CHP) of the Department of Health is today (April 10) investigating a case of severe paediatric influenza A infection and an outbreak of upper respiratory tract infection (URI) at a kindergarten-cum-child care centre in Kowloon Tong.

The severe paediatric case involves a 27-day-old baby girl with good past health, who has presented with runny nose since April 7 and developed fever and cough yesterday (April 9). She was taken to the Accident and Emergency Department at Prince of Wales Hospital for medical attention yesterday and was admitted today for management. She was subsequently transferred to the Paediatric Intensive Care Unit of the hospital for further management.

Her nasopharyngeal aspirate tested positive for influenza A virus upon laboratory testing. The clinical diagnosis was influenza A infection complicated with severe pneumonia. She is now in a serious condition.

Initial enquiries revealed that the patient had no travel history during the incubation period. Her father developed cough and runny nose recently and has sought medical attention. He is in a stable condition and no hospitalisation is required. Her other home contacts have remained asymptomatic so far.
