H7N9 Influenza A

In April 2013, an outbreak of human infections caused by an avian influenza A (H7N9) virus was first reported in China by the World Health Organization. As of May 2014, the outbreak has resulted in more than 400 lab-confirmed human infections. The infection has been fatal for 1 n 4 of those ill.  The virus was subsequently detected in poultry. There is no evidence of sustained spread of the virus between people, and most people that were infected have had known contact with poultry. There have been no cases detected in the United States. Influenza viruses are constantly changing and it's possible that the influenza A (H7N9) virus could change enough to spread among people. People can protect themselves and others from influenza infection by washing their hands, covering their mouths when they cough or sneeze, and staying home when they are sick. 

For more information about influenza, both novel and seasonal, see the Public Health Division Influenza page.
