H7N9 avian flu

The influenza A (H7N9) virus is one subgroup among the larger group of H7 viruses that normally circulate among birds. A number of human infections of the H7N9 virus have been reported in eastern China, mostly in the Yangtze River Delta region since late March 2013. Some of the patients have died of severe pneumonia brought on by the virus.

Three patients who have contracted the H7N9 strain of bird flu had visited the Longgang district of Shenzhen, including the latest case announced yesterday, mainland health authorities said.

A 38-year-old Shenzhen man was in critical condition after being diagnosed with the deadly strain of the flu, Shenzhen's centre for disease control and prevention said.

The patient is a migrant worker who lives and works in Nanwan Street, in Longgang district, near one of the infected markets where authorities found the H7N9 virus on December 11.

A second patient, a 39-year-old man from Dongguan, commuted to the district. The pair follow Tri Mawarti, a domestic helper who was the first person in Hong Kong diagnosed with the virus. She is believed to have handled a live chicken at a flat in Nanwan Street before falling ill.

Four people have been confirmed as having contracted the H7N9 virus in Guangdong in five days. The province has confirmed six cases since August; two in Dongguan , two in Yangjiang , one in Huizhou and yesterday's case.

Cheng Jinquan, the centre's director, said at a news conference that the second patient from Dongguan and the Hong Kong patient had been to Longgang district before falling ill.

"The 39-year-old Dongguan patient commuted to work in the Ganlan area in Longgang district in Shenzhen," Cheng said. "The Hong Kong domestic helper from Indonesia also travelled to Shenzhen in late November.

"There's no further evidence to prove they got infected in Shenzhen because both are still in a coma and could not give information," he said.

The Shenzhen patient saw a doctor on December 9 at a local clinic after developing a fever. He went to hospital on Thursday last week and was transferred to another clinic the next day with severe pneumonia.

Hong Kong's public hospitals have stepped up their bird flu tests on patients.

Hospital Authority chief executive Dr Leung Pak-yin said yesterday that all patients with pneumonia and flu-like symptoms were required to be tested for bird flu, even if they had not come into contact with birds or poultry or travelled recently.
