In addition to its ban on arrivals from several European countries, Singapore has toughened up the rules for everyone else too.

Passengers who enter Singapore from now on and show respiratory symptoms, like a fever or a cough - will have to serve a stay at home notice for 14 days, even if they have tested negative for the coronavirus.

Singaporeans have also been told to exercise caution when they travel to countries where some cases have come from recently: the UK, the Philippines and Indonesia.

The message from the government is simple: the number of coronavirus cases coming from outside Singapore - what they call imported cases - is rising. And they’re going to do whatever they can to stop that from spreading through the local community.

Singapore has just announced some of its toughest measures yet to slow the coronavirus outbreak in the tiny city state.

Its decision on Friday effectively bans travel to and travellers from Italy, France, Spain and Germany.

If you are a Singaporean citizen or have permanent residency here, and are coming from those places, then you will be subject to a 14 day stay at home notice. That means not leaving your house for those two weeks, under any circumstances.
