The Swedish Public Health Agency reported Thursday a national outbreak of monophasic Salmonella Typhimurium. As of October 3, 33 people have been confirmed infected.


Whole genome sequencing (analysis of the bacterium’s genome) has shown that the disease cases have been infected with the same strain of Salmonella Typhimurium and are thus suspected of having been infected by a common source of infection.

The cases, which are aged 2-89 years (median = 29 years), are native to seven different regions in Sweden. Most people under the age of 18 (16 cases) and people over the age of 60 (13 cases) have been infected. More women (21 cases) than men (12 cases) fell ill. 

The affected infection control units, together with the National Food Administration and the Swedish Public Health Agency, are investigating the outbreak to identify the source of the infection, which is suspected to be a food with a wide distribution in Sweden.
