Step up surveillance to stop bird flu spread from China
Von Dobschuetz said China was assessing the virus' prevalence and results were expected in the coming weeks. Since the virus was first identified in 2013, 1,320 human cases have been recorded in China, including 492 deaths, according to FAO figures. But in February Beijing reported it detected an evolution in the virus that caused severe disease and death in poultry within 48 hours of infection. ; Please credit the Thomson Reuters Foundation, the charitable arm of Thomson Reuters, that covers humanitarian news, women's rights, trafficking, property rights, climate change and resilience. "The earlier you pick up the incursion of the virus the more chance you have to control it," von Dobschuetz told the Thomson Reuters Foundation by phone.He said: "There is currently no publicly available vaccine to protect against the H7N9 virus infection. The first confirmed infections of the new H7N9 strain of bird flu were reported on mainland China in March 2013. Signs and symptoms of H7N9 infection in people mainly start with a fever and cough. As of Saturday, there were a total of 1,329 confirmed human H7N9 cases around the world since the 2013 outbreak, claiming at least 492 lives. Scientists analysed the DNA of H7N9 virus strains collected since the 2013 outbreak, and identified a gene mutation that allowed it to adapt to human cells.
