Via the Centre for Health Protection: Imported human case of avian influenza A(H7N9) confirmed. Excerpt:
The Centre for Health Protection (CHP) of the Department of Health today (January 11) reported that the suspected imported human case of avian influenza A(H7) affecting a boy aged ten last night (January 10) had been laboratory confirmed. This is the fourth human H7N9 case in Hong Kong this winter.
His nasopharyngeal aspirate tested positive for influenza A(H7N9) virus upon laboratory testing of the CHP's Public Health Laboratory Services Branch.
Contact tracing has so far identified 27 close contacts and 70 other contacts.
Close contacts are the patient's family and school contacts as well as relevant in-patients and visitors of Princess Margaret Hospital (PMH). All have remained asymptomatic. They will be given antiviral prophylaxis with oseltamivir (Tamiflu) for five days, advised to wear a mask and put under medical surveillance for ten days following their last exposure to the patient.
Other contacts include the patient's school contacts, healthcare workers (HCWs) of North Lantau Hospital and PMH as well as ambulance personnel in patient transfer. Four HCWs of PMH have mild symptoms. Two of them were tested negative for influenza A and two are pending testing. The others have remained asymptomatic. They will be advised to wear a mask and will be put under medical surveillance for ten days following their last exposure to the patient.
From 2013 to date, 20 imported human H7N9 cases, including 13 males and seven females aged from five months to 85 years (median: 66.5 years), have been confirmed in Hong Kong, with seven deaths (35 per cent).
"In view of the upcoming Lunar New Year holidays, adults and parents should look after children with extra care in personal, hand, food and environmental hygiene against infections during travel," a spokesman for the CHP said.
