Bird Flu Virus Is Capable of Human Spread, Ferret Studies Show
The bird flu virus that’s killed 36 people in China is capable of human-to-human spread, scientists found in animal studies that highlight its pandemic potential.
Ferrets experimentally infected with the new H7N9 strain passed it to other ferrets occupying the same cage, indicating the virus’s ability to spread via direct contact, researchers at the Chinese Center for Disease Control and Prevention in Beijing and the University of Hong Kong said. Flu transmission in ferrets is a predictor of patterns in humans, the authors said in the study, published yesterday in Science Express.
The research will help health officials tailor their response to the H7N9 strain, which is known to have infected 131 people since March, mostly through contact with virus-laden poultry. No cases have been reported since May 8, weeks after authorities curbed live poultry sales in the eastern cities of Shanghai, Nanjing and Hangzhou. So far, there is no evidence of sustained human-to-human transmission — a feature required for flu to spark a pandemic — the World Health Organization said. Read more of this post
