"It is a management of common sense, of wisdom", he told journalists about the use of masks.

Throughout events during the day, Marcelo Rebelo de Sousa was oscillating between wearing a mask or not using it, either in smaller spaces or in wider spaces.

"There were 140 people, or 150 people, in a space that was large, but despite everything there were many people, and they were all wearing masks. I understand, out of respect for the people who were wearing masks, and as a matter of common sense and precaution, I put on the mask," he said.

He added that those who want further reassurance should take a test.

"Today, even antigen tests are very accessible. If you have doubts about that... I did an antigen test this morning, because yesterday I had some contacts, I went to places where there were a lot of people, some with a mask and others without a mask, and I pre-emptively did that," he reported.
