The Malaysian man had travelled to Singapore last month for a meeting with colleagues from China - including one from Wuhan, the epicentre of the epidemic. He showed symptoms of fever on January 29, nearly a week after returning home.
Malaysia's Health Minister Dzulkefly Ahmad said the 41-year-old man was admitted to the isolation ward. He was confirmed positive for the coronavirus on February 3.
The other new case announced on February 3 was a Chinese national from Wuhan who has been in Malaysia since Jan 18. The 63-year-old man was isolated.
