Pandemic Concerns for H5N1 Wild Bird Flu in Finlandelement115

H5N1 in Scandinavian countries would be particularly dangerous. In 2003 there was an outbreak of H7N7 in the Netherlands. Over 30 million birds were culled. However H5N7 isolates were found, indicting H7N7 had reassorted with H5N2. Reassortment, or swapping of whole genes, happens during dual infections, when the same host is infected with two different viruses. The H5N7 isolated in 2003 from a mallard duck in Denmark was novel and signaled new genetic combinations between H5 and H7 viruses.
