Spanish health authorities said they would test hotel guests and staff.

The doctor was the third case identified in Spain after a German tourist in La Gomera, another Canary Island, and a British man in Mallorca.

"We are checking people who had contact with the patient, including the people in the hotel," a spokeswoman for the Canary Island's health department said.

Betts, a British national from Leicestershire, said they had been allowed to have breakfast in the hotel restaurant.

"We were originally told to go back to our rooms after breakfast, but we haven't done so, and everyone else seems to be talking around reception as normal. But unfortunately, no one has any more information as yet, they're all waiting for the health authorities."

He said he had not been tested for the virus yet and had missed his flight home.

Hotel employees were wearing masks, but none were provided to the guests, Betts said. Video he provided from inside the hotel showed people carrying on normally, except for the masks.

Other hotel staff were waiting outside on the parking lot, unable to get into the hotel, footage shows.

H10 Costa Adeje Palace hotel will not comment, a receptionist at the Barcelona-based company managing the hotel said.

The hotel has a capacity for hundreds of guests, several restaurants and several swimming pools and is located 50 metres from the beach. On its Facebook page, the H10 Costa Adeje Palace said it planned a carnival party on Thursday evening.

Tens of thousands are expected this week in the Canary Islands for carnival festivities.
