The Irish Government is advising citizens whose presence in China is "not essential" to leave the country.
The Department of Foreign Affairs also says anyone with underlying medical conditions should not travel there.
In updated travel advice, it says this is "a precautionary measure".
Citizens are being advised to contact their travel agency or airlines for available routes out.
The advice remains at 'Avoid non-essential travel' - the second-highest level of alert.
It comes after the Department of Health's National Public Health Emergency Team (NPHET) met earlier on Tuesday, amid the ongoing coronavirus outbreak.
It says there are still no confirmed cases here - but that Ireland is well positioned to detect and respond to a case that might arise.
The NPHET will meet again next Tuesday.
Meanwhile, the first meeting of the Expert Advisory Group, to be chaired by Dr Cillian De Gascun, will take place on Wednesday.
It adds: "Ireland will continue to monitor the situation and to participate in the international assessment of response to this novel Coronavirus through the European Centre for Disease Control and the WHO."
