Several cities, states, regions and countries have tied travel restrictions (e.g. quarantine) to live health metrics. With those metrics changing daily, travel restrictions can change daily. Is there a public dataset or database which can provide a list of restrictions which apply to people considering travel between location A and location B? If not, what are good sources of US & global travel restriction data to populate an open database?
