Denmark began reopening schools for younger children on Wednesday after a month-long closure to combat the novel coronavirus, becoming the first country in Europe to do so.

Nurseries, kindergartens and primary schools were restarting after they were officially closed on March 17 in an effort to curb the COVID-19 epidemic, though many had shut before then.

However classes are only resuming in about half of Denmark's municipalities and in about 35 percent of Copenhagen's schools, as others have requested more time to adjust to health protocols. All are expected to reopen by April 20.

The children quickly settled into the reorganised classrooms designed to comply with strict new sanitary guidelines.

"I feel great, really good about the kids going back to school," Caroline, a 38-year-old and mother of two, told AFP.

In early April the country's centre-left government announced that schools would be reopened "on the condition that everyone keeps their distance and washes their hands."

But while schools are gradually reopening, bars, restaurants, hairdressing and massage parlours, shopping centres and discos remain closed, and gatherings of more than 10 people are banned.

Schools are required to ensure that a distance of two metres (about six feet) is maintained between desks in classrooms and recesses must be organised for small groups.

A headache for teachers is that they must ensure that pupils are never in groups of more than two while inside and five outside.

To adhere to guidelines, the school in Norrebro has divided the classes into two or three groups, limiting the number of students in a classroom to 12.

Bottles with hand sanitiser are never far away to encourage students to clean their hands regularly.

"We have the space because we're using the classrooms usually used by the older grades who are working from home now," said headmaster Henrik Wilhelmsen, adding that it would present an issue when older students also return.

Some parents have opposed the reopening of schools, citing health concerns. A petition dubbed "My child is not a guinea pig" has garnered some 18,000 signatures.

Wilhelmsen told AFP that around 15 parents had informed the school that they would not bring their children back.

Others however trust their government's judgement.

"I think we're all going to be sick at one point and they told us the children are going to be less sick and affected by this virus," said Caroline, the mother.

"I think it's good that they're going back to school... We need to go back to daily life," she added.

Middle and high school students will however continue remote classes and are only expected to return to classrooms on May 10.

According to the latest figures on Wednesday morning, Denmark had 6,876 confirmed cases of the new coronavirus and 299 deaths.

Before Denmark, Austria was the first European country to unveil its roadmap for a return to a "new normal".

On Tuesday, it allowed small non-food shops to open up, while maintaining social distancing rules and requiring masks to be worn in shops and on public transport.

Austria plans to keep schools, cafes and restaurants closed until at least mid-May.
