Only 14 patients from China's H7N9 bird flu outbreak are still in hospital, national health authorities said in their latest update on the disease. http://medicalxpress.com/news/2013-06-china-h7n9-patients-left-hospital.html Diseases, Conditions, Syndromes Mon, 10 Jun 2013 05:20:01 EST news290058553 Earlier this month, the U.S. government declared that the emerging H7N9 bird flu "poses a significant potential for a public health emergency." The virus, a relative of other bird flus we've seen previously like H1N1 and H5N1, originated in China and results in a severe respiratory infection and, in some cases, death. While the virus is not, at this time, transmissible between humans, researchers believe that just a few genetic mutations could change that. Network scientist Alessandro Vespignani, the Sternberg Family Distinguished University Professor of physics, computer science, and health sciences, is mapping the disease's progression in his lab. We asked him to discuss the pandemic potential of the virus and explain how this strain differs from those in the past. http://medicalxpress.com/news/2013-05-bird-flu-virus.html Diseases, Conditions, Syndromes Tue, 14 May 2013 07:10:06 EST news287733012 On 31 March 2013, the Chinese National Health and Family Planning Commission announced human cases of novel H7N9 influenza virus infections. A group of scientists, led by Professor Chen Hualan of the Harbin Veterinary Research Institute at the Chinese Academy of Agricultural Sciences, has investigated the origins of this novel H7N9 influenza virus and published their results in Springer's open access journal Chinese Science Bulletin. http://medicalxpress.com/news/2013-05-bird-flu-poultry-source-viruses.html Diseases, Conditions, Syndromes Mon, 13 May 2013 11:07:31 EST news287662044 In March 2013, a novel H7N9 influenza virus was identified in China as the etiological agent of a flu-like disease in humans, resulting in some deaths. A group of scientists, led by Professor Chen Hualan (National Avian Influenza Reference Laboratory, State Key Laboratory of Veterinary Biotechnology, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences) have investigated the origins of this novel H7N9 influenza virus (Shi et al., 2013). Following analysis of H7N9 influenza viruses collected from live poultry markets, it was found that these viruses circulating among birds were responsible for human infections. These novel H7N9 viruses are reassortants in which the six internal genes were derived from avian H9N2 viruses; however the origins of their hemagglutinin (HA) and neuraminidase (NA) genes were unclear. http://medicalxpress.com/news/2013-04-source-identification-h7n9-influenza-virus.html Diseases, Conditions, Syndromes Thu, 25 Apr 2013 00:00:04 EST news286045191 The ongoing dance between a virus and its host distinctly shapes how the virus evolves.
