An outbreak of Salmonella has ended in Sweden with officials unable to find the source of infection.
In October, 40 people became ill with monophasic Salmonella Typhimurium with the majority falling sick in the first half of the month. An earlier update identified 33 patients. Cases were linked by whole genome sequencing.
As no new illnesses have been recorded after late October, the outbreak was recently judged to be over by authorities.
Sick people were 2 to 92 years old with a median age of 44. They lived in eight different regions.
