What if Mother Nature plays just as large a role in shaping the course of human events as mankind? After all, any force that compels specific actions by nation-states is necessarily geopolitical.

Often, but not always, such interspecies transmission occurs following mutations in the pathogen’s genome that make it more suitable for targeting a new host. But, infectious disease is not a one-way street. This same evolutionary process also makes possible “reverse zoonosis” (more properly dubbed zooanthroponosis) — i.e., the transmission of disease from humans to animals. Continue reading

Since May of this year, 440 Chinese people have been infected with a new strain of influenza subtype H7N9, and 122 of them have died. Though the case-fatality rate suggested by this data is greatly inflated by asymptomatic and mild (and hence, unreported) cases, a new analysis in Trends in Microbiology suggests that the virus has the potential to become the next influenza pandemic.
