This will be the most defining and drastic event of the decade/generation (hopefully nothing worse comes along anyway). Similar to how the Great Depression, WWII, Vietnam/Cold war and social movements and 9/11 and the wars in Afghanistan/Iraq in 2000s were for previous generations of Americans. The economic, logisitcal and political ramifications are massive.
I doubt international/air travel will be affected nearly as much as when security was massively increased due to terrorism/drugs, but that depends entirely on how soon we get a vaccine and how effective it is.
I am still so thankful that children are relatively unaffected by COVID-19 and that Corona-type viruses generally don’t mutate as quickly as something like influenza. After the tragedies of Zika virus what a relief that the very young will be relatively safe.
