Table 1. Input values used to estimate the expected change in the number and incidence (cases/100 000 inhabitants) of reported domestic human salmonella cases in Sweden in 2010 in the different scenarios.
Input values | SE | DK | NL | References |
Total number (incidence) of reported cases (2010) | 3 609 (38) | 1 598 (28.7) | 2 291*(8.8) | SE [3], DK [10], NL [11] |
Proportion domestic of the total number of reported cases (2010) | 23.4% | 54.8% | 90% | SE [3], DK [10], NL [11] |
Number of reported domestic (travel related) cases in Sweden(2010) | 845 (2764) | SE [3] | ||
Population (2010) | 9 408 320 | 5 560 628 | 16 654 979 | SE [12], DK [13],NL [14] |
Multiplier (data source 1) | 134 | 289 | 1 064 | [5] |
Underdetection index UDI (data source 2) | 1 | 1.8 | 7.7 | [7] |
Under-reporting factor URF (data source 3) | 0.5 | 4.4 | 26.3 | [8] |
Multiplier (data source 4) | 10 | 17 | 20 | [6] |
Multiplier (data 5) | 6.7** | 10*** | 16.6**** |
* Laboratory surveillance data from RIVM NL covers only 64% of the population. Cases adjusted to cover whole population: 1466/0.64 = 2291.
