Previous studies have shown that dogs are susceptible to influenza A viruses, and the close contact between dogs and humans poses a threat to public health. In 2015, a novel H3N8 influenza virus was isolated from a dog in eastern China. This strain was characterized by whole-genome sequencing with subsequent phylogenetic analysis and genetic comparison and found to be most closely related to avian influenza viruses co-circulating in China. It was able to replicate in mice without prior adaptation. The continued circulation of this novel H3N8 influenza virus in dogs could endanger other mammalian species.

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum ( in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
