Spain has issued lockdown orders for some 46 million people who are only permitted to leave their homes for essential work, food shopping, medical reasons or to walk the dog.
Yesterday, a total of 2,640 troops had disinfected the country's main airports and ports along with retirement homes and prisons, General Miguel Angel Villarroya, chief of the defence staff, told the same news conference.
On Thursday, police arrested 55 people for not respecting the lockdown that was put in place at the weekend, under which Spain's 46 million population can only leave home to shop for food or medicine, go to the hospital or go to work.

Meanwhile, in Switzerland coronavirus cases rose 25% to 6,100 and deaths rose to 56 in the past 24 hours, the Swiss health ministry said.
It also said hospitals in the canton of Ticino that borders on hard-hit Italy were under pressure.
"The situation in Ticino is very tense," said Daniel Koch, head of the Federal Office of Health's communicable diseases division.
The latest tally nationwide is up more than 1,200 cases in a day, while the deaths were up 13 from yesterday.
The Swiss military took delivery of 50 additional ventilators and deployed them in Ticino yesterday, amid a global race by countries to add more potentially life-saving breathing devices needed by critically ill patients to give them a fighting chance of survival.
Speaking at a press conference in Bern, Mr Koch said the 25% rise in Swiss cases in 24 hours did not come as a surprise, given Switzerland only this week heightened restrictions on events and gatherings, including limits on groups in public to five people, with each keeping a 2-meter distance, under threat of a fine.
