I’ve been impressed with Singapore’s response so far. They seem to be keeping it contained, and have good tracking. When I looked today, they only had 102 cases and 72 had recovered with no deaths so far.
Someone posted that Singapore even randomly tests at routine dr appointments now.
Singapore also has the considerable advantage of having a tropical rain forest climate.
If one is looking for a “canary”, at this point I’d say South Korea. Possibly Italy.
