Singapore likely will have it under control for the general population within this month, the issue they are now having is trying to control the spread among the foreign workers which is difficult due to the conditions that they live. 97 to 99% of the new cases are all being spread through the dormitories.
Not to confuse a foreigner working in Singapore like my, but the term “Foreign worker” is government defined:
Definition of foreign worker
2. The Minister hereby —
(a) fixes the salary referred to in paragraph (a) of the definition of “foreign worker” in section 2 of the Act to be not more than $2,000 a month; and
(b) specifies that for the purposes of the Act a foreign worker shall include a person who is not a citizen of Singapore who seeks employment with, or is offered employment by, or is in the employment of, an employer at a salary of more than $2,000 a month and who does not hold an employment pass issued under the Immigration Act [Cap. 133].
