The Norwegian Institute of Public Health has seen an increase in the number of people infected with the gastrointestinal bacterium Salmonella typhimurium in recent months. So far this year, infection has been detected in 33 people living all over Norway. Domestic infection is suspected, but the cause is currently unknown.
The Norwegian Institute of Public Health receives continuous notifications of all confirmed S salmonella cases.
– Especially since the month of April, we have seen an increase in cases of Salmonella Typhimurium that have been infected in Norway compared to the last three years, says doctor Hilde Marie Lund.
The infected live all over the country and are distributed across all age groups. The reason for the increase is currently unknown.
– We have therefore, in collaboration with the Norwegian Food Safety Authority and the Veterinary Institute, initiated enhanced monitoring of all confirmed cases of S. Typhimurium in Norway. A selection of the people who are infected are followed up with an interview so that we can find out if they have a common source of infection, explains Lund.
