Salmonella-associated deaths, Sweden, 1997-2003.
We examined excess deaths after infection with Salmonella in a registry-based matched cohort study of 25,060 persons infected abroad and 5,139 infected within Sweden. The domestically infected have an increased standardized mortality ratio, whereas those who acquired Salmonella infection abroad had no excess risk of death.
