Health Minister Vili Beros said on Monday 6,236 health workers in some 60 medical institutions were tested today, when Covid certificate mandate was introduced in the health sector, and that 20 of the tests came back positive.

“That’s another irrefutable argument that the measures are necessary for protecting patients and workers,” he tweeted.

Not one test came back negative and four staff did not show up for testing at KBC Zagreb, Croatia’s biggest hospital, where a protest was held this morning against mandatory certificates and testing.

As of today, every employee in the health and social care sectors as well as visitor must have a Covid certificate. Medical workers without it must be tested twice a week.

The chambers of physicians and nurses supported the mandatory certificates, saying they will contribute to patient’s safety, while condemning the protests held outside some hospitals, saying they disrupted the peace patients need for their treatment.
