(Thanks to Mary Marshall for alerting me to the typo in the headline!) The Centre for Health Protection has published Epidemiological investigation and follow-up actions by CHP on confirmed human case of avian influenza A(H9N2). Excerpt:
The Centre for Health Protection (CHP) of the Department of Health (DH) today (December 31) provided an update on the confirmed human case of avian influenza A(H9N2) affecting a man aged 86.
"The epidemiological investigations, enhanced disease surveillance, port health measures and health education against avian influenza are all ongoing," a spokesman for the DH said.
The patient's home contact in Shenzhen has remained asymptomatic.
The 51 health-care workers (HCWs) of North District Hospital (NDH) and the ambulance service remain under medical surveillance. Among them, an HCW of NDH presented with productive cough and sore throat and the respiratory specimen tested negative for the influenza A virus upon testing by the CHP's Public Health Laboratory Services Branch (PHLSB).
The officer who handled the patient upon his entry at Lo Wu Border Control Point is also asymptomatic. He has been put under medical surveillance. So far, there are no newly located contacts.
As the patient was staying in Shenzhen for the whole incubation period, the case is classified as an imported one. The CHP has passed investigation findings to the health authority of Guangdong for follow-up.
"Upon analysis by the PHLSB, the genes of the virus were determined to be of avian origin. They do not show significant differences from avian influenza viruses detected in Hong Kong and the Mainland in recent years. There is no evidence of genetic reassortment with genes of human influenza origin or resistance to the antiviral Tamiflu. We will continue to liaise and share the gene sequence with other health authorities based on established arrangements," the spokesman remarked.
The public is advised to avoid contact with poultry and wild birds, including chickens, ducks and sparrows.
"Travellers, especially those returning from avian influenza-affected areas and provinces with fever or respiratory symptoms, should immediately wear masks, seek medical attention and reveal their travel history to doctors. Health-care professionals should pay special attention to patients who might have had contact with poultry, birds or their droppings in affected areas and provinces," the spokesman advised.
