The recruiting firm Indeed has asked Irish employees to work from home until next week.
It says this is after one of its workers in Singapore "may have been exposed to coronavirus", after their family members visited a facility caring for a coronavirus patient.
In a statement, the company says: "While there are no confirmed cases of infection, out of an abundance of caution for the health and safety of our employees, we have asked all employees in Singapore, along with anyone who has recently visited our Singapore offices, to work from home until February 17th.
"Since some employees who visited Singapore have recently visited our Sydney and Dublin offices, we are asking all employees in the Dublin and Sydney offices to work from home until we have received confirmation.
"Business continues uninterrupted across the globe", it adds.
The firm has more than 1,000 employees in Dublin and over 9,000 worldwide.
It comes as the number of confirmed coronavirus cases in Britain has doubled with four more people testing positive.
Across Europe, there are 14 cases in Germany, 11 in France, three cases in Italy, and one each in Belgium, Finland, Spain and Sweden.
There are no confirmed cases of the virus in Ireland.
China announced on Monday 27 foreigners have been infected inside the country, including two deaths - as the total number of deaths in China reached 910.
