  • Abstract: China is currently experiencing its fifth epidemic of “bird flu,” or avian influenza H7N9, since 2013 when it was first noted to cause human infections. The virus, which is mainly transmitted from poultry to humans, is also prone to limited human-to-human transmission. To date, there have been 1,258 human cases, with one-third of those cases (460) occurring during this year’s epidemic alone.[1] There are many “subtypes” of avian influenza circulating in birds around the world and most of these viruses cause limited or no human infections. However, two avian influenzas subtypes causing high human mortality have jumped from birds to humans in the last decade, H5N1 and then H7N9. The significant potential of this class of viruses to cause a human pandemic is a global public health concern, particularly because the conditions leading to the rise of these infections are becoming more favorable — for the viruses.
