Best yet is to fund measures to minimize disruptions and to help manage the economic meltdown caused by pandemics. And plan accordingly. The world was utterly unprepared to deal with a pandemic. Once we were somewhat better equiped with knowledge (ie. aerosols in closed spaces), procedures (widespread testing, ventilation, etc) and equipment (masks, ICU beds) the economy could function much closer to (a new) normal. But even today, if it weren't for vaccines, we would not be remotely close to where we are now, at least in some countries. A lot of the measures implemented were useless, including tech (ie phones), which failed to be of real service tracking contacts and infections.

Once enacted, countries or regions that don't abide to my wishful set of international rules on pandemic measures will be isolated or excluded by the community. Money otherwise would flow to implement measures everywhere and keep the world economy going at a good pace.

Here's a review on what I consider a great investment for these financial aids, making air filtering/ventilation and CO2 control ubiquitous:

Also the economy would had suffered a lot less if there was a predictable schedule on how restrictions and, even stricter, lockdowns were applied according to some economists.
