Public Health Wales (PHW) says it is carefully monitoring the threat for the Chinese coronavirus after concerns that a Welsh resident had become infected.
The patient was tested for the virus and results came back negative, but the agency says it has put in place proportionate, precautionary measures in case of an outbreak.
Dr Giri Shankar, Professional Lead Consultant for Health Protection at PHW, said: “We are working with our partners in the other UK nations, the WHO and others to monitor this new and rapidly evolving situation."
He said available evidence showed the risk to the UK remained low.
Globally confirmed cases of the virus have soared to over 800. In China, 26 people have died.
More than a dozen people in the UK have now been tested for the virus, according to Public Health England.
Five people have tested negative while a further nine are awaiting results.
The government said four of five people who were tested in Scotland were thought to be Chinese.
On Thursday afternoon, Health Secretary Matt Hancock told the Commons he expected cases of the virus "to rise further".
He added that the UK is one of the first countries to develop a world-leading test for coronavirus and that the NHS is ready to respond appropriately to any cases that emerge.
"The public can be assured that the whole of the UK is always well prepared for these type of outbreaks and we will remain vigilant and keep our response under constant review in light of emerging scientific evidence," Mr Hancock said.
The Foreign Office has advised against all but essential travel to Wuhan.
Flights to the UK arriving from China continue to be monitored as a precaution.
Meanwhile the World Health Organisation has said it is "too early" to declare an international public health emergency over the outbreak.
"The Emergency Committee on the new coronavirus (2019-nCoV) considered that it is still too early to declare a public health emergency of international concern given its restrictive and binary nature."
Speaking at a press conference, Dr Tedros Adhanom Ghebreyesus, director-general of the WHO, said: "Make no mistake, this is though an emergency in China. But it has not yet become a global health emergency.
"It may yet become one."
