What *can* be done about travel?
HIV & Ebola don't have vaccines, yet we've changed behavior to severely limit their spread. If travel is the vector for COVID19, what behavior change must happen?

Love it! But this won't help for asymptomatic people. OTOH, maybe we will discover that asymptomatic don't spread as much, & getting those with even very minor lung symptoms to quarantine will help. Another problem: unfairly targets vapers, smokers, those w asthma or COPD.

Asymptomatic people that are infectious will breathe out some characteristic molecules.

In a less ideal world, we weight the cost of contact tracing and potential infections against the cost of immigration quarantines.
