View the time-enabled maps
See the time-enabled maps, created by Nature reporter Declan Butler, showing the spread of human cases and outbreaks of infection in animals over time since 2003. Install Google Earth 4.0 to view these maps correctly – please note that earlier GE versions are not supported. Then use this new link to download the updated time-enabled maps.
Once you have downloaded the map inside Google Earth, you will see a time bar at the top of the screen (see screenshot above). Click the button at the right-hand side of this bar to view the time series. For best viewing, set the speed of playback to slowest. And to ensure it all works correctly, right click on the left-hand side of the bar, and select "" clamp beginning of time window."
