ADEJE, Spain — Hundreds of guests at a resort on Tenerife, the largest of the Canary Islands, were told Wednesday that they would be confined to their hotel for 14 days as the authorities tried to prevent the coronavirus from spreading after infections were discovered there this week.

News of a quarantine at the resort, the H10 Costa Adeje Palace, came as officials in Europe scrambled to contain an outbreak that has spread to at least seven nations on the Continent. Spain, of which the Canary Islands are a part, disclosed additional infections on Wednesday, and France reported its second death.

The Costa Adeje Palace, a four-star resort with a restaurant, pools and over 450 rooms, is one of at least two hotels to be locked down in Europe. Officials in Innsbruck, an Austrian ski town, sealed off a 108-room hotel after an employee tested positive for the virus.
