TY - JOUR AU - Bhoumik, Priyasma AU - Hughes, Austin L. T1 - Reassortment of Ancient Neuraminidase and Recent Hemagglutinin in Pandemic (H1N1) 2009 Virus T2 - Emerging Infectious Disease journal PY - 2010 VL - 16 IS - 11 SP - 1748 SN - 1080-6059 AB - Sequence analyses show that the outbreak of pandemic (H1N1) 2009 resulted from the spread of a recently derived hemagglutinin through a population of ancient and more diverse neuraminidase segments. This pattern implies reassortment and suggests that the novel form of hemagglutinin conferred a selective advantage.
