Episode 49 Eastern Equine Encephalitis: Triple EEEk!

In 2019, eastern equine encephalitis (EEE), a viral disease transmitted by mosquitoes, made headlines in much of the US as cases skyrocketed compared to previous years. But why is this disease so feared and even more importantly, why is it on the rise? Those are just a couple of the questions we seek to answer on this week’s episode. From the nitty gritty on what this virus does to your body to centuries-long forest dynamics in Massachusetts, we connect the disease ecology dots of EEE. We promise, the biology and history of eastern equine encephalitis is much more exciting than its etymology.
