Zoonosis Summary A zoonosis is an infectious disease that is transmitted between species (sometimes by a vector) from animals other than humans to humans or from humans to other animals. Of the 1415 recognized species of human pathogens, 61% are of zoonotic origin [Taylor 2001]. These include Hendra, Nipah, Machupo, Ebola, Influenza A, SARS-CoV, Yersinia pestis, Borrelia burgdorferi, Plasmodium knowlesi. Use of comparative genomics to understand zoonotic spillover – what are the genetic determinants that allow an animal virus to adapt to human
16
H7N9 use case In February and March 2013, several human cases of influenza virus A H7N9 subtype were identified in Shanghai, China and surrounding provinces. As of August 12, 2013, a total of 135 human cases have been laboratory confirmed, including 44 deaths for a case fatality rate of 33%. A search for H7 influenza strains in IRD (data accessed from www.fludb.org on April 8, 2013) returned a total of 1485 strains, with 1306 from birds, 102 from environmental samples (usually bird droppings), 33 from horses and only 17 from humans prior to the recent outbreak. www.fludb.org Of the 17 human H7 isolates, 12 were H7N7 from England 1996 and the Netherlands 2003. None were H7N9. Questions – Where is the reservoir source of this newly emerging human pathogen? What are the genetic determinants allowing for human adaptation?
