SINGAPORE - Three more Singaporeans, including a junior college teacher, have been confirmed to be infected with the coronavirus and have no known links to previous cases or travel history to China, the Ministry of Health (MOH) said on Friday (Feb 7).

Among the infected patients, two have been discharged. Of the remaining 31 cases, most are stable or improving, but two are in critical condition in the intensive care unit.

Here is what we know of the three new patients confirmed on Friday.
