Update - Singapore is banning arrivals for work visa holders as well, unless they work in ‘essential services’
From 23 March 2020, 2359 hours, all short-term visitors (from anywhere in the world) will not be allowed to enter or transit through Singapore. Furthermore the Ministry of Manpower will only allow the entry/ return of work pass holders [2], including their dependents, for those providing essential services, such as in healthcare and transport.
