The Cluster at the Marina Bay Sands this week (the Hotel with the infinity pool everyone thinks of when people say “Singapore”) was probably the cluster that broke the camels back.
That and putting up all the malaysian workers in Dormitory’s (since the border was closed) was keeping the Virus alive to the tune of 75 new cases/day.
I arrived at the MBS on January 19th, and checked out on the 25th. The night before, everything was normal. The next day, much fewer people and everybody had masks. We were watching news from China and started prepping the day we got back to the States. It was obvious from the Chinese response that this was serious.
