Avian Influenza H7N9 Response

In March 2013, three human infections with a novel avian influenza A(H7N9) virus were identified in China.

By June 30, 2013, a total of 132 patients infected with this virus were reported in mainland China, and 43 of these patients died.

After detection of this novel virus, six targeted surveillance and sampling programs were implemented in Beijing, China, to identify possible cases.
