Two outbreaks of cryptosporidiosis associated with cattle spring pasture events.
Over a period of less than four weeks, 50 human cases of cryptosporidiosis were reported from a relatively small geographical area in Sweden. All cases were associated with visits to cattle spring pasture events at two farms (referred to as Farm A and B). Epidemiological and microbiological evidence show that contact with calves at the farms was the most likely source of Cryptosporidium infections. Gp60 sequences from human and calf isolates at Farm A were identical to each other, but differed from those at Farm B where, again, human and calf gp60 sequences were identical, proving that the two outbreaks had no common origin. As a direct consequence of these two outbreaks, and guided by knowledge gained from the outbreak investigations, the Swedish Board of Agriculture and all relevant farmer advisory organizations have updated their hygiene instructions for farm visits.
