>>In the middle of the 14th century, Sweden was struck by the Black Death.[28] The population of Sweden and most of Europe was seriously decimated. And the population (at same territory) as existed by 1348 did not reach the same numbers again until the beginning of the 19th century. One third of the population died during 1349–1351.
Authors can be wrong in interpreting the available (or lack of available) information. According to Ole Benedictow, there is little or no surviving records of plague in Sweden, but I would be curious to know why Larsson and Marklunds interpret that as that there was little plague there?
True.
Also I'm not saying people didnt die. But from what I've read, it was not such a huge deal as it has been painted out to be in Sweden. Remember, health care back in those days meant people died from all sorts of things. Perhaps there is a lack of information or it simply was not a big deal. Different people are also more or less sensitive to different bacteria and viruses.
