Yeah, they actually do. The Spanish Flu is a pretty great example. It just happens that the main form of transoceanic travel took long enough that people were easier to quarantine. And it still caused as much death as it did. Pandemics like Covid haven’t happened before but they’ve been predicted for decades. When you can cross the entire earth in less than 48hrs, all it’s going to take is the right virus to show up. Covid was particularly good at transmitting in that way, because it has a long asymptomatic infectious period both before and after the symptomatic phase. Especially if you compare it to the og SARS-CoV-1, which didn’t spread as readily across oceans and borders.
