Via the Centre for Health Protection: Second confirmed human case of avian influenza A(H7N9) in Hong Kong under CHP investigation. Excerpt:
The Centre for Health Protection (CHP) of the Department of Health (DH) is today (December 6) investigating another confirmed human case of avian influenza A(H7N9) in Hong Kong affecting a man aged 80.
The patient, with underlying medical condition, lives in Shenzhen. He was admitted to a hospital in Shenzhen for management of his chronic illness from November 13 to 29.
On December 3, he arrived in Hong Kong with his three family members via Shenzhen Bay Port Border Control Point (SBP BCP) and subsequently took a taxi there in the afternoon to the Accident and Emergency Department (AED) of Tuen Mun Hospital (TMH) where he was admitted for further management of his chronic illness on the same day.
The patient had no fever upon admission. However, he developed fever this morning and was put under isolation immediately. His nasopharyngeal swab was tested positive for the avian influenza A(H7N9) virus upon laboratory testing by the Public Health Laboratory Services Branch of the CHP today.
The patient will be transferred to Princess Margaret Hospital for isolation. His current condition is stable.
Initial investigation by the CHP revealed that his family members who had either accompanied him to or visited him in TMH have remained asymptomatic.
"The Serious Response Level under the Government's Preparedness Plan for Influenza Pandemic has been activated while the CHP's epidemiological investigation and follow-up actions are currently in full swing," a CHP spokesman remarked.
The spokesman urged the taxi driver who had taken the male patient on wheelchair and his three family members comprising one man and two women at SBP BCP at about 2.15pm on December 3 and arrived in the AED of TMH at about 2.50pm to contact the CHP hotline (2125 1111) immediately.
Contact tracing for his family members in Hong Kong, patients in TMH who stayed in the same cubicle with the confirmed patient as well as healthcare workers in TMH and relevant hospital visitors are under way. They will be put under medical surveillance.
This is the second confirmed human case of avian influenza A(H7N9) in Hong Kong.
The CHP will issue letters to doctors and hospitals to keep them abreast of the latest situation.
"The confirmed case has been notified to the World Health Organization, the National Health and Family Planning Commission (NHFPC) as well as health and quarantine authorities of Guangdong and Macau," the spokesman said.
So both of Hong Kong's H7N9 cases appear to be "imported" from Shenzhen. It would be interesting to know what the mainland authorities are doing about their local wet markets.
