A brief announcement today from the Shanghai Department of Health and Family Planning gives us the bare-bones details on what is their first reported case of H7N9 case of this fall. During the first two waves (spring 2013, winter-spring 2014), Shanghai was the fourth most active region in China, reporting 41 human infections.
With more than 24 million people, Shanghai is China’s most populous city, and was one of the first regions to report H7N9 in the spring of 2013.
While we watch all human infections with novel influenza viruses with concern, H7N9 has spread faster to humans than any other avian flu virus, and studies suggest it continues to evolve towards becoming a `mammalian adapted’ virus. Over the past month we’ve begun to see an uptick in human infections in China, and more cases are expected as we get deeper into the winter season.
