In Serbia, coronavirus restrictions are being tightened as more high-profile figures become infected. Several towns are now considered COVID-19 hotspots in the country.

Kragujevac is one of them. The city of around 200,000 people announced a state of emergency after reporting hundreds of new cases in just a few days.

Now, the restrictions lifted just weeks ago have been re-introduced.

"Citizens must learn to live with the coronavirus. It won't be eradicated until a vaccine is developed since it is constantly returning. If a certain part of the population has to catch it, our goal is for not all of us to get sick at the same time so that the health system can withstand the pressure," said Radomir Nikolic, Mayor of Kragujevac.

It doesn't appear that the threat is being taken too seriously on the city's streets. Playgrounds are full of children and parents, and very few wear face coverings.

In Belgrade, there was no social distancing at last week's election victory celebration at the headquarters of the ruling Serbian Progressive Party. The room was crowded, and very few were seen wearing face masks.

The video clip filmed on the night shows that Serbia's defense minister Aleksandar Vulin was standing in the crowd, with no mask on. Next to him were Serbia's health minister, and the minister of European Integration.

Three days later, Vulin announced that he'd tested positive for COVID-19.

Maja Gojkovic, speaker of the National Assembly, was present at the same event, who was seen standing right next to prime minister Ana Brnabic. The two were seen hugging.

Just a few days later, Gojkovic was admitted to hospital for COVID-19.

Earlier in the week, former Serbian player and manager Ilija Petkovic died of coronavirus, while tennis star Novak Djokovic tested positive.

These high profile cases and rising new cases have raised fears of second wave of infections in the Balkan country.
