Palau's government is investigating a potential case of Covid-19 coronavirus.
The Ministry of Health said a woman, 73, from the US had "underlying conditions" and was in isolation at the Belau National Hospital.
The patient went to Palau with a visiting medical team.
The ministry is planning to send a patient specimen for Covid-19 testing to a Center for Disease Control laboratory today.
President Tommy Remengesau Junior issued a statement reassuring the public.
"Palau and our partners at the CDC are equipped to manage the situation should the patient receive a positive test. As in so many situations like this, fear, not a germ, is our biggest enemy."
Meanwhile, Palau is anticipating a further drop in tourism revenue with the president asking his ministers and government to "exercise financial caution" as they ride out what he calls a "black eye" amid the coronavirus fears.
Palau, which relies on tourism, has experienced a nearly 50 percent drop in arrivals in February and tourism officials say it's expecting a further drop in March.
The death toll from the flu-like disease has passed 3000 worldwide. The disease appears to be spreading more rapidly outside China, where the virus emerged.
