Human infection from avian-like influenza A (H1N1) viruses in pigs, China

Emerg Infect Dis. 2012 Jul;18(7):1144-6. doi: 10.3201/eid1807.120009.

Abstract

In investigating influenza in an immunodeficient child in China, in December 2010, we found that the influenza virus showed high sequence identity to that of swine. Serologic evidence indicated that viral persistence in pigs was the source of infection. Continued surveillance of pigs and systemic analysis of swine influenza isolates are needed.
