Influenza B viruses with mutation in the neuraminidase active site, North Carolina, USA, 2010-11

Emerg Infect Dis. 2011 Nov;17(11):2043-6. doi: 10.3201/eid1711.110787.

Abstract

Oseltamivir is 1 of 2 antiviral medications available for the treatment of influenza B virus infections. We describe and characterize a cluster of influenza B viruses circulating in North Carolina with a mutation in the neuraminidase active site that may reduce susceptibility to oseltamivir and the investigational drug peramivir but not to zanamivir.
