How badly has COVID19 impacted excess deaths?

We at PANSOC have been co-authoring a preprint that might help answer that question using 100 years of data from three countries including Sweden, Switzerland and Spain. We looked at age adjusted monthly estimates of excess mortality to show that in 2020 these countries recorded highest monthly excess and all-cause mortality levels driven by an infectious disease since the 1918 pandemic.
