Singapore was early in restricting travel from affected areas in China and had experience in tracking and isolating those who slipped through.
Experience from the SARS, MERS and other Corona virus epidemics helped- Having a decisive government also helped in limiting the early spreading of the virus in Singapore.
It is harder to keep control now, with a much wider spread of the virus in the world. Singapore being a travel hub and major port are exposed to a lot of potential sources of contamination-
Yet the number of cases is only 345 so far, with 221 still in Hospital and 124 recovered:
Not bad in a population of 5.6 Mill…(many of whom are foreigners on long term visas)
The thousands of day trippers coming across the causeway to work, or attend school etc. every day has a hard time after Malaysia closed their borders:
Could the rest of the worlds have something to learn from Singapore??
PS> I forgot to mention that Singapore still have not had any deaths from COVID-19
