 Hey, Ari. Any idea why the virus is surging now? So a couple of reasons. Number one, this is a mosquito borne virus and it's been a warm, wet year in South America. So there's a lot more mosquitoes around. Mosquitoes are also thriving in more places thanks to climate change. So that's number one. Number two is that dengue is cyclical. There tend to be big outbreaks every couple of years. The last big one was in 2019. And part of the reason for that is that there's actually four different strains of dengue.
