Hong Kong health officials confirmed Tuesday afternoon a human case of H9N2 infection, a mild form of avian influenza, the first of its kind during the past three years in Hong Kong.
Dr. Thomas Tsang, the Controller of the Center for Health Protection of the Department of Health, said a 9-month baby has been confirmed with A H9 bird flu influenza, during a press briefing here Tuesday afternoon.
Tsang said the baby, who lives in Tseung Kwan O of the New Territories, showed symptoms of fever beginning on March 4 and was hospitalized on March 6. She recovered on March 9 and her parents and grandma did not show symptoms of avian influenza.
Preliminary medical testing revealed the baby was infected with the H9N2 strain of the avian influenza.
Tsang said the baby has never been outside Hong Kong but her family once took her to the marketplace to buy live poultry.
The baby is currently under medical observation in Princess Margaret Hospital and health authority has conducted blood testing for her family members.
Tsang said it will take another week to carry out further genic testing of the case and the results would be released next week.
Tsang said Hong Kong health authority has notified the World Health Organization and the Ministry of Health of the H9N2 avian influenza case.
Hong Kong once reported two human H9N2 avian flu cases in 1999, involving a four-year-old child and a 13-month-old baby. And in 2003, a five-year-old child was also confirmed to be infected with the H9N2 avian flu virus. All the three patients infected with the H9N2 recovered.
