A new Swedish study found that just 7% of people in Stockholm had caught the novel coronavirus COVID-19 by the end of April.<br />According to Business Insider, Swedish forecasters had previously predicted up to half the population would catch the virus by May.<br />However, epidemiologists say at least 60% of people need to catch the virus before any protective immunity can be achieved.<br />Sweden has not implemented strict, wholesale lockdown measures in response to the coronavirus pandemic.<br />Instead, the country has largely allowed businesses to remain open and students to attend school.<br />Sweden this week overtook the UK, Italy, and others to become the country with the highest number of coronavirus deaths per capita.<br />Professor Tom Britton helped devise the model Sweden's public health agency is using.<br />It's surprising the forecasts are so wrong.
