Sweden famously took a totally different approach to its Nordic neighbours in trying to contain the spread of the novel coronavirus. The Swedish strategy allowed people to keep living largely as normal. Stores and restaurants remained open - so too did many schools. With a COVID-19 death toll of 5,700, Sweden's mortality rate from the disease is now around a quarter higher than that of the United States, when adjusted for population size. However, authorities insist that the number of deaths has considerably dropped in recent weeks. "We've actually seen a clearly declining trend in the number of patients in intensive care and also in the number of deaths since the middle of April," said Anna Mia Ekstrm ... at Stockholm's Karolinksa Institute. So how close is Sweden to possibly reaching herd immunity? We don't know at this point. Scientists are still trying to figure out whether immunity from the new coronavirus can even be reached - and for how long. Ekstrm noted that the reproduction number of the epidemic - or R number, which measures the average number of people that one infected person will pass the virus on to - has now fallen in Sweden to around 0.6, meaning transmission is declining. The number of people with antibodies against the new coronavirus, meanwhile, is increasing. Data published by Sweden's public health agency in June showed that about 10 per cent of people in Stockholm - the nation's worst affected area - had developed antibodies to COVID-19, more than anywhere else in the country.
