Health Minister Vili Beros, who is isolating at home because he has coronavirus, said on Saturday the situation with the number of infections and related deaths was alarming and announced that he would talk with county heads on Tuesday.
Speaking for RTL television via video link, he again called for people to be more responsible.
"Tuesday is an important day, when all of us at the national level will once again talk with prefects, which will be an opportunity for the national, local and regional governments to hold constructive talks and assess all problems."
Asked if that meant they would discuss new restrictions, Beros said every opportunity was good for talks.
He said many were criticising the national COVID response team's measures, but added that many in the world claimed that milder restrictions would be effective if people complied with them.
"We can impose stricter measures, but if people won't wear masks and (if they) socialise at private gatherings... Everything is an opportunity to show responsibility."
Asked if it was realistic for a vaccine to be in Croatia by Christmas, Beros said, "We joined early enough all European initiatives for procuring vaccines from various manufacturers. As a state, we have done everything. Now it's all up to the manufacturers."
