Nature’s Avian Flu e-newsletter for June is just out. If you’d like to sign up for monthly updates from Nature Reports Avian Flu, our extensive archive of news about and research articles reporting the most significant developments on avian flu, please go to the Avian Flu website. Each newsletter brings you free updates — this month including an account of how researchers are gaining a stronger appreciation of the effect of human behaviour on the course of epidemics, as well as about the origins of influenza and other major infectious diseases. Other developments include the prospects of new antibody-based treatment for H5N1 infection, and a resolution by WHO to stockpile vaccines against influenza viruses with pandemic potential. The Nature Reports Avian Flu website carries a regularly updated timeline, FAQs, and Nature’s award-winning interactive Google Earth map that enables users to see the spread of the H5N1 avian flu virus over time around the world. Share your views on the Nature Reports Avian Flu blog.
