China H1N1 Sequences Target Lung
January 16, 2014
The WHO Chinese National Influenza Center operated by the Chinese CDC in Beijing released H1, N1, and MP sequences from 27 isolates from Beijing, Shanghai and 11 provinces throughout eastern China. The samples were collected between September 3 and December 4 from patients who were almost exclusively under 65. Remarkably, 14 of the sequences were from egg isolates and almost all had at least one of the receptor binding domain changes that target human lung.
