To date, 36 cases from 10 counties have been linked with whole-genome sequencing. Most cases have been reported from Västra Götaland, Jönköping, Halland and Dalarna. Ill persons are found in all age groups, both among children and the elderly, and slightly more women (22) than men (14) have become sick.
The Swedish National Food Agency and the Public Health Authority together are investigating the outbreak to identify the source of the infection that is suspected to be a food that has been widely distributed in Sweden.
Authorities said they suspect both are foodborne but do not yet know the source.
Since the beginning of May, 13 cases of an unusual Salmonella type (S. Typhimurium MLVA 2-17-N-N-211) have been identified by Folkhälsomyndigheten’s (Public Health Agency’s) microbial monitoring program.
