Since the beginning of May 2018, thirteen cases of an unusual salmonella type (S. Typhimurium MLVA 2-17-NN-211) have been identified by the Public Health Authority’s microbial monitoring program, according to the Public Health Agency of Sweden, aka Folkhalsomyndigheten (computer translated).


The type has so far been identified in seven counties in persons reported to be infected in Sweden. The sick people, seven men and six women, are between 10 and 85 years old.

An investigation is being carried out in collaboration with the relevant infectious agents and other authorities to identify the source of infection.

Salmonella is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea, nausea, vomiting, and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis, and arthritis.
