Oseltamivir-resistant pandemic (H1N1) 2009 virus infections, United States, 2010-11

Abstract

During October 2010-July 2011, 1.0% of pandemic (H1N1) 2009 viruses in the United States were oseltamivir resistant, compared with 0.5% during the 2009-10 influenza season. Of resistant viruses from 2010-11 and 2009-10, 26% and 89%, respectively, were from persons exposed to oseltamivir before specimen collection. Findings suggest limited community transmission of oseltamivir-resistant virus.

Geographic distribution of oseltamivir-resistant pandemic (H1N1) 2009 viruses in the United States, October 1, 2010–July 31, 2011. Numerators are number of oseltamivir-resistant viruses identified by state public health laboratories; denominators are number of pandemic (H1N1) 2009–positive specimens submitted by each state for susceptibility testing. Gray shading indicates states that had >1 infection with oseltamivir-resistant virus.
