Novel influenza a (h1n1) is a new flu virus of swine origin that was first detected in mexico and the united states in march and april, 2009 the first novel h1n1 patient in the united states was confirmed by laboratory testing at cdc on april 15, 2009 the second patient was confirmed on april 17, 2009 it was quickly. Subject: pro/edr influenza (07): seasonal, h1n1, research as many as 180 patients in the twin cities of rawalpindi and islamabad have so far tested positive for influenza virus (swine flu) [influenza a(h1n1) virus] while at least the cdc reports over 4000 us deaths a week from flu and pneumonia.
We integrated empirical findings on whether the media dramatized h1n1 on a global scale through systematically reviewing prior content-analytic studies review also revealed a critical gap in existing knowledge about the tone of media coverage on h1n1, and discusses implications for future research on dramatization.

Note: much of the information in this document is based on studies and past experience with seasonal (human) influenza cdc believes the information applies to 2009 h1n1 (swine) viruses as well, but studies on this virus are ongoing to learn more about its characteristics this document will be updated. Viral tracking and research internationally, scientists have been collaborating on genetic analysis of current animal and human influenza viruses these researchers have created a human/swine a/h1n1 influenza wiki to facilitate rapid dissemination of the results of this work the collaboration is producing.
Swine flu is a highly contagious respiratory disease in pigs caused by one of several swine influenza a viruses (see the image below) transmission of swine influenza viruses to humans is uncommon however, the swine influenza virus can be transmitted to humans via contact with infected pigs or.
