Masks will be mandatory at retail stores starting on Monday. The new measure will also apply to workers at cafes and restaurants, but not customers. Masks are already required on all forms of public transportation.

The coronavirus task force has also enacted new measures to curb the spread of the virus at large gatherings such as weddings, which have accounted for a large number of new cases in recent weeks. Organizers of all events with more than 100 people will be required to notify public health authorities 48 hours earlier and will also have to present a list of all participants and their contact information.

Public health officials said they were not bringing down the hammer, but they warned the public to give serious consideration to whether such events are worth the risk.

"They have to keep in mind that large social gatherings do place their loved ones at risk. Everyone should consider if that is the way they want to proceed," said Dr. Alemka Markotić, the head of the Infectious Diseases Clinic in Zagreb.

Croatia will also try to make Covid-19 testing more accessible. Testing for the coronavirus is free for individuals who have symptoms and are sent by their doctors, but public health authorities are promising to make testing cheaper for everyone else. Health Minister Vili Beroš posted on Facebook on Saturday that the government would work on negotiating a fairer price for elective testing, which currently costs about 1,500 kuna.
