It could also be due to the "gross candy" buying and consumption habits that seem rather prevalent as part of the popular cultural in at least parts of the Nordic countries.
Hmm... I grew up in an Indian village in 1980-87 with a pack of dogs to play with and a pond to swim in. Later during University in Bombay (1994-99) I had malaria thrice and thyphoid once, the latter probably originating from the office building 'canteen'. I think that is sufficient exposure to pathogens. The bloody dagis virus still gets me everytime I get in multiday contact with my nieces.
