Health chiefs in the region confirmed the holidaymaker was one of five suspected new cases currently being analysed.
The age of the unnamed man, thought to be the first British tourist in Spain affected since the country announced its first cases last week, has not been revealed.
Authorities have not said if he is holidaying alone or with relatives who are also being tested.
Spain, one of the worst affected countries, has so far confirmed around 40 cases and said another 67 people are being tested.
Outbreaks there have been traced to a gay sauna in Madrid and a Gran Canaria pride festival attended by 80,000 people from Britain and other European countries.
