According to [0] Sweden has 11,445 cases and 1,033 deaths (CFR: 9%) as of 6pm PT 4/14. For a population of 10.3 million [1], this is a confirmed infection rate of 0.11%.
According to [2] California has 23,338 cases and 758 deaths (CFR: 3.2%) as of 6pm PT 4/14. For a population of 39.5 million [3], this is a confirmed infection rate of 0.06%.
By all accounts, Sweden is being hit far harder by this virus than California or Sweden’s own neighbors are, and based on this evidence it is reasonable to infer that the distancing measures or lack thereof have an effect on transmission.
