Two Irish passport holders have tested positive for Coronavirus.
The pair were on board a cruise ship in Japan, where the illness broke out.
The Princess Diamond Cruise Ship is currently docked off Yokahama.
The Irish citizens also hold passports for another EU country, and do not live in Ireland.
They are currently being treated in hospital in Japan.
The Department of Foreign Affairs says it is "in close contact" with those who remain in quarantine.
It says it is "reviewing our travel advice on a regular basis".
