By reconstructing a phylogeny we can learn about important epidemiological phenomena. By adding geography to where the sample was taken we can map the spatial spread of a pathogen as well as how it may be changing in a certain location. By looking at this in context by adding in different geographies (environment, population, economics) we can then start to understand what might be driving changes.
Over the last number of years we have heard about Zika, Chikungunya, Mpox, Covid-19, etc. What I find fascinating about the geophylogenies provided here are how a pathogen circulates locally in an area before going global.

And just in the Americas

Geography is cool! See the other diseases they have included on their website.
