Well this is a different topic - the issue I was addressing was the utility of weekly data presented by ciceryadam, which you were questioning.

As to you new point - you are drawing your conclusions from disparate data sources, whilst ignoring confounding factors (as pointed out by ljf). The data on wikipedia give a less dramatic picture, and after adjusting for population things look even less dramatic (10.0 -> 10.8 per 1000 for Slovakia and 9.0 -> 9.5 for Sweden). I don't think you can draw serious conclusions from such limited data.
