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.
The development was “worrying” and should be closely watched, Chinese researchers said, but stressed that the virus, believed to jump from birds to people, was still not adept at spreading among humans.Thursday, 29 August, 2013, 4:13am
A Chinese woman who spent five weeks in intensive care with H7N9 bird flu has given birth to a girl in what was described as a “miracle” first, state media said on Friday.
Qiu Yan, 25, was five months pregnant when she was diagnosed with the virus in April, early in China’s human outbreak of the disease.19 Jul 2013 - 2:24pm 1 comment
Japan's health ministry has stepped up monitoring of the spread of the H7N9 flu virus after studies warned it could trigger a pandemic because Japanese people lack natural immunity.14 Jul 2013 - 6:30am
The death toll from the H7N9 bird flu outbreak in China has risen to 43, national health authorities said in their latest monthly update on the disease.11 Jul 2013 - 11:42pm
They based their conclusion on the fact that the virus has caused more human infections in a shorter period than any other bird flu virus, and that it has undergone genetic changes that suggested it is better adapted to infecting humans.2 Jul 2013 - 5:01am 2 comments
The deadly H7N9 strain of bird flu that broke out on the mainland in February appears to have died down in recent weeks but could strike again in the autumn if it follows the pattern of the H5N1 virus, University of Hong Kong researchers warn.

The H7N9 bird flu that hit China this year killed over a third of hospitalised patients, putting the severity of the infection between swine flu and the H5N1 avian virus, said researchers on Monday.
In a study published on Monday, University of Hong Kong researchers analysed data from most of the 132 H7N9 avian influenza patients since its emergence three months ago.29 Aug 2013 - 4:13am
Taiwan reported the world's first human case of H6N1 bird flu infection yesterday but appealed for calm, saying no sign of human-to-human transmission had been detected.

No new cases of H7N9 bird flu have been confirmed in Shanghai since the middle of last month, but many residents are still worried about eating chicken and pork.
Cold-processed poultry meat has now been allowed back on the market following the removal of an alert and many Shanghai residents believe live poultry markets will reopen soon.1 Jun 2013 - 4:20am
Laboratory tests have revealed resistance in some H7N9 bird flu patients to the only available treatment, said virologists who unveiled “concerning” study results on Tuesday. Three out of 14 patients monitored at a clinic in Shanghai had a genetically-mutated version of the virus that makes it drug resistant, a team of researchers in China wrote in the journal The Lancet.29 May 2013 - 10:55am 1 comment
The H7N9 bird flu virus may combine with the swine flu and mutate into a new virus strain, a University of Hong Kong research team warns.25 May 2013 - 5:41am
The H7N9 bird flu virus can be transmitted not only through close contact but by airborne exposure, a team at the University of Hong Kong found after extensive laboratory experiments. Though the virus appears to have been brought under control recently, the researchers urged the Hong Kong authorities to maintain strict surveillance, which should include not only poultry but humans and pigs.24 May 2013 - 5:50am 4 comments
The H7N9 virus appears to have been brought under control in China largely due to restrictions at bird markets, but caused some US$6.5 billion in losses to the economy, UN experts said.
Health authorities worldwide must be on the lookout to detect the virus, which could still develop the ability to spread easily among humans and cause a deadly influenza pandemic, the experts said.23 May 2013 - 5:01am
The world is unprepared for a massive virus outbreak, the deputy chief of the World Health Organisation warned on Tuesday, amid fears that H7N9 bird flu striking China could morph into a form that spreads easily among people.29 Aug 2013 - 4:13am
No new human cases of the H7N9 virus have been recorded in China for a week, national health authorities said, for the first time since the outbreak began in March.
One previously infected patient died in the week beginning between May 13, the National Health and Family Planning Commission said in a statement late on Monday, taking the total number of fatalities from the virus to 36.29 Aug 2013 - 4:13am
