H7N9 avian flu

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.

Scientists propose creating super strains of H7N9 bird flu virus

Scientists propose creating super strains of H7N9 bird flu virus

A group of scientists are proposing to conduct controversial experiments on the new H7N9 bird flu virus that may involve creating more potent strains to examine how they might spread among humans.

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.

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.

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.

They called for vigilance to be maintained.

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.

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.

The patient, a 20-year-old woman who worked at a breakfast shop in Changhua county, central Taiwan, was admitted to hospital on May 8 with a high fever and respiratory problems, health officials said.

H7N9 outbreak may be over, but pall of suspicion hangs over Shanghai

H7N9 outbreak may be over, but pall of suspicion hangs over Shanghai

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.

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.

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.
