A probe is being conducted by the World Health Organisation after three virus infection which was linked to a business meeting in Singapore last month. This has led to the heightened fear of the spread of the disease outside of China.
This has turned out to be the evidence to prove that the coronavirus has been spreading through human-to-human contact outside China. The WHO believes that it is deeply concerning and could lead to a much larger outbreak.
"WHO is coordinating with relevant ministries of health in relation to it," spokeswoman Olivia Lawe-Davies said in response to questions from Reuters. "As countries are stepping up surveillance, the detection of more cases of local transmission can be expected."
Cases reported in South Korea and Malaysia because of the meeting
The cases, in Malaysia and South Korea, have been linked to a 100-strong meeting in Singapore of staff from an as-yet-unnamed multinational sales firm, while one Chinese delegate was from the central city of Wuhan, where the virus originated.
The sister of a Malaysian who attended has since been infected, while Singapore said virus symptoms had surfaced in four of the firm's local staff. Authorities have not revealed the name of the company, although Korea has said it was an international sales firm.
Malaysia offered the first revelation when it confirmed the case of a 41-year-old citizen who had attended the meeting at the plush Grand Hyatt hotel near the city-state's Orchard Road shopping district. South Korea then confirmed two cases involving its citizens who had also attended. The Koreans and the Malaysian shared a buffet meal during the conference, South Korean media said.
Of 109 meeting participants, 94 were from overseas and have since left Singapore, its health ministry said, adding that four local staff were referred to the National Centre for Infectious Diseases.
Hotel to carry out sanitization of the guest rooms
The hotel will carry out "thorough sanitization and deep cleaning" of guest rooms that were potentially affected and will monitor staff and guests for symptoms, its general manager, Willi Martin, said.
Singapore has reported 28 cases of the coronavirus, some involving domestic transmissions. Several firms in Singapore have suspended business and media events, including a big travel fair and hotel trade show, but the Singapore Airshow will go ahead next week, although on a smaller scale.
On Thursday, China reported its biggest daily jump in deaths from the virus, an increase of 73 to 563, although only two deaths have been reported outside mainland China.
