Sweden has suffered its deadliest day during the coronavirus pandemic with 185 people succumbing to the disease overnight.

Despite the increase in fatalities, Sweden is the only country in Europe not to have implemented harsh lockdown laws – meaning pubs and stores are still widely open.

Deputy State Epidemiologist Anders Wallensten informed the public that Sweden's death toll was now 1765 from 15,300 confirmed cases.

Dr Wallensten believes Sweden may have reached a peak of the disease but that is yet to be reflected in the data.

"Already a bit more than a week ago, the peak was reached, at least according to this model, and we can expect fewer cases each day," Dr Wallensten said.

"But you also have to remember ... that two-thirds have not been infected and can still get it."

Sweden's capital Stockholm is the centre of the outbreak in the country, but unlike much of the continent its borders are not closed.

Gyms, cafes, schools, bars, workplaces and retail shopping all remain open, but gatherings of more than 50 people have been banned and educators have been recommended to move what they can online.

The nation's head epidemiologist Anders Tegnell is the government strategist behind Sweden's relaxed approach to fighting the disease.

He has argued that strong messaging around social distancing – without harsh restrictions and fines – means Sweden will be able to maintain virus protocols for much longer.

"It is important to have a policy that can be sustained over a longer period, meaning staying home if you are sick, which is our message," Dr Tegnell said.

"Locking people up at home won't work in the longer term.

"Sooner or later people are going to go out, anyway."

A minimal domestic flight schedule is ongoing in the country, but the borders are not closed.

According to John Hopkins University, Sweden has the 20 th highest number of confirmed cases in the world and is ranked 13 th in the world for number of fatalities.

Any Swedish resident over the age of 70 has been urged to stay home, and several outbreaks of the virus have been recorded throughout the country's aged care facilities.

A study by Imperial College in London calculated that approximately 3.1 per cent of the Swedish population was infected, compared to 0.41 per cent in Norway and 2.5 per cent in the UK.
