While the infection rate in Sweden is thankfully dramatically reduced, it should also be noted that Sweden has reported more infections than:

Denmark, Finland, Norway, Estonia, Latvia, Lithuania, and Poland

COMBINED.

Additionally, we generally are seeing reduced cases in cooler climates at the moment and increases in warmer climates. The reverse of which was true in the late winter and spring.

My personal theory is that air conditioning in the heat and heating in the cold with the increased likelihood that clusters of people are inside enjoying these amenities leads to more cases. My prediction is that the warmer places with high case loads will taper off in the fall and rising case loads will return to the colder regions.
