Travel restrictions helped Vietnam control #covid19 — as part of a robust public health response.

This doesn& #39;t mean they& #39;ll work for every country, or that they& #39;re needed for every health threat. https://www.vox.com/22346085/covid-19-vietnam-response-travel-restrictions">https://www.vox.com/22346085/...

I keep thinking about something @shoffmania said in particular... there are something like 200 events that could go pandemic each year. How do you pick which ones to shut down for? Will the public accept inevitable "overreaction"?

For travel restrictions to work, you need to do them before community transmission...

This also means it is harder for countries with big travel hubs to act quickly enough. But again, they& #39;re most useful when they most seem like overkill.

This is an interesting paper on the last time the WHO recommended a travel advisory -- for Sars-1. The Canadians among us might remember the Rolling Stones answer to that one -- SarsFest. (I was there and think @rameswaram was too) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7106206/">https://www.ncbi.nlm.nih.gov/pmc/artic...

So it& #39;s an interesting and nuanced issue -- tough to get right. But there& #39;s lots we can learn from Covid and the responses in countries like Vietnam.
