What good are hand sanitizers when the virus is primarily spread through the air?
If you're that afraid, wear gloves when you're outside.
By the way screening body temperatures is useless, because the virus has a very long period without symptoms - including fever.
The Samsung store at Vivocity has a bottle of hand sanitizer next to the S20 phones.
Also, inside the Harbourfront MRT station near Vivocity's entrance were two uniformed guards, each carrying a big gun.
Something like this, but bigger. And they were wearing berets, not police.
