"As of 28 January 2020, 12pm [04:00 a.m.], the Ministry of Health (MOH) has confirmed additional two imported cases of Wuhan coronavirus infection in Singapore. Five confirmed cases were earlier announced by MOH," the ministry said in a statement.
The sixth and seventh cases are two men, aged 56 and 35, who are both Chinese citizens from Wuhan, according to the statement.
The ministry has advised citizens of Singapore to refrain from visiting mainland China in general and the Hubei province, where Wuhan is located, in particular.
"MOH will continue to monitor the situation closely. As medical practitioners are on the lookout for cases with pneumonia [among those] who have recently been in China, Singapore is likely to see more suspect cases that will need to be investigated for possible links to the Wuhan cluster," the ministry concluded.
Singapore confirmed the first case of the coronavirus, originating from China's city of Wuhan, on 23 January.
Multiple cases of the new coronavirus have been reported all over the world following its initial discovery in Wuhan with a lot of infected being Chinese travellers.
