Profile and generation of reduced neuraminidase inhibitor susceptibility in highly pathogenic avian influenza H7N9 virus from human cases in Mainland of China, 2016-2019.

Abstract excerpt

Human infections with highly pathogenic avian influenza (HPAI) H7N9 virus were detected in late 2016. We examined the drug resistance profile of 30 HPAI H7N9 isolates from Mainland of China (2016-2019). Altogether, 23% (7/30) carried neuraminidase inhibitors (NAIs) - resistance mutations, and 13% (4/30) displayed reduced susceptibility to NAIs in neuraminidase (NA) inhibition test. An HPAI H7N9 reassortment virus...
