Figures from a survey by the state-run Centre for Sociological Studies (CIS) showed 95 percent of respondents believed the measures to fight the epidemic were necessary or very necessary.
Spain has suffered one of the most-deadly outbreaks of the epidemic, counting more than 231,000 cases and 27,000 deaths, although the numbers peaked on April 2nd.
Six out of 10 respondents said they believed the strict conditions of the lockdown, which was imposed on March 14 but is being slowly eased, should be extended for longer, while 29 percent said they wanted more freedom of movement.
But the population appears divided over how the government of Prime Minister Pedro Sanchez has handled the crisis, with 46 percent saying they had a lot or quite a lot of confidence in its policies, while 48 percent said they had little or none.

Renewed four times, the state of emergency has let the government impose some of the world's tightest restrictions on Spain's nearly 47 million population, although it has since begun a cautious rollback which is due to finish by late June.
The state of emergency is set to expire on May 23rd at midnight but the government will on Wednesday seek parliamentary approval to extend it one more time.
If approved, it would mean the state of emergency would last until late June.
