Toddler's H9N2 infection under study

24 December, 2009

The Centre for Health Protection is investigating a mild form of avian influenza A/H9N2 found in a 35-month-old girl.

The toddler lives in Sha Tin. Since late November, she had developed a cough, fever and runny nose and was admitted to Prince of Wales Hospital. She has since recovered, and was discharged on December 11.

Lab tests found the avian influenza virus in samples from her respiratory system. Such H9N2 infections in people are rare, and are usually mild.

This is the seventh time that H9 viruses were found in people in Hong Kong since 1999.
