Chinese expert warns of possible H1N1-H5N1 mix
Chinese respiratory disease expert Zhong Nanshan said the country must be alert to any H1N1 mutation, because the far deadlier H5N1 avian flu is endemic in China, according to a Reuters report today. "China . . . is different from other countries," he said. "Inside China, H5N1 has been existing for some time, so if there is really a reassortment between H1N1 and H5N1, it will be a disaster."
