Swine Flu

The World Health Organization declared the first flu pandemic in 41 years on 11 June 2009. As details of the global impact of the 2009 influenza A (H1N1) virus — and efforts to combat the threat — unfold over the coming months, Nature News provides breaking news and authoritative analysis of the science and the politics behind the headlines.


Dealing with Pandemics

  • FAQ: Avian Flu

    Is there going to be a pandemic? History suggests that this question is a matter of when, rather than if. Flu pandemics occur every 30-70 years, as newly evolved flu viruses sweep across entire world regions infecting enormous numbers of people.

  • In vitro and in vivo characterization of new swine-origin H1N1 influenza viruses

    Most human infections with swine-origin H1N1 influenza viruses (S-OIVs) seem to be mild; however, a substantial number of hospitalized individuals do not have underlying health issues, attesting to the pathogenic potential of S-OIVs. To achieve a better assessment of the risk posed by the new virus, we characterized one of the first US S-OIV isolates,as well as several other S-OIV isolates, in vitro and in vivo.

  • Evolutionary analysis of the dynamics of viral infectious disease

    The rapid evolution of many important pathogens, particularly RNA viruses, means that their ecological and evolutionary dynamics occur on the same timescale. This Review discusses the insights into the transmission and epidemiology of viruses that have been provided by analyses of their evolutionary dynamics across a wide range of biological scales.
