There is one new case of Covid-19 today in managed isolation. The new case is a woman in her 30s who travelled from London. She tested positive on her third day in a quarantine facility.
Cases of coronavirus in Spain have tripled in the past three weeks as more new infections were linked to young people partying or going for mass drinking sessions, health authorities said.
Since one of Europe's strictest lockdowns came to an end last month, Spaniards have relaxed back into daily life and the number of clusters have soared to 201 across the country.
The occurrence of Covid-19 cases have jumped from eight cases per 100,000 at the end of June, when the country's state of emergency ended, to 27 per 100,000, according to data from the Spanish health ministry.
It is the same ratio per 100,000 of population as when Spain started to ease out of lockdown measures on May 11.
"Where measures have been relaxed is where these clusters appear," Health minister Salvador Illa said.
A study by the Carlos III Institute in Madrid found the number of people aged 15 and 29 who tested positive for coronavirus was now triple that of those aged between 60 and 69 and 70 and 79.
In Cordoba, in southern Spain, 73 people tested positive for the pathogen after a disco and 670 people who came into contact with the partygoers have been traced by authorities.
The highest number of outbreaks have been found in Catalonia, Aragon and the Basque Country.
Fernando Rodríguez Artalejo, spokesman of the Spanish Epidemiology Society, said: "In these regions, the situation is very worrying. If they don't bring them under control now and in a firm way, we will have a very complicated situation."
Over the weekend 4581 new cases were recorded, bringing the total to 264,836. More than 28,400 people have died.
Illa said the situation in Catalonia was of concern and appealed to residents to follow advice not to leave their homes.
On Friday, the Catalan regional government urged some four million people, including tourists visiting Barcelona, to stay at home and avoid gatherings of more than 10 people.
Authorities also told bars and restaurants to reduce their capacity to 50 per cent and closed cinemas, theatres and gymnasiums.
Barcelona city council has on Tuesday limited access to its beaches after they had to be closed by police at the weekend after they became overcrowded.
The Catalan government has ordered a localised lockdown, affecting 160,000 around Lleida.
To try to prevent more outbreaks all regions except Madrid and the Canary Islands have made wearing masks compulsory even when social distancing can be maintained.
