Twelve cases of Salmonella Enteritidis disease have been linked using whole genome sequencing (analysis of the bacterium’s genome). Eight of the twelve patients are children under the age of ten and the cases are resident in ten different regions. All cases except one have fallen ill on January 20 or later (figure). There are as many women / girls as men / boys who have fallen ill.

The affected infection control units and the Swedish Public Health Agency are jointly investigating the outbreak to identify the source of the infection.
