Figure 1.
Outcome tree for Campylobacter spp. (a) and Salmonella spp. (b) – an illustration. Note:
*Only severe GE cases are at risk to develop ReA. ** Non-fatal severe GBS cases may develop permanent disability. *** For reasons of simplicity we assume that only severe GBS cases may be fatal.
Figure 2.
Assuming a downwards time trend for an infection having symptoms in the same years (a) and for an infection where symptoms occur only after 10 years (b). Note:
Blue rectangles represent the number of infections in the year of infection (exposure to an infection). Green “cans” represent the number of cases with symptoms; where these symptomatic cases occur in the same year as the infection (a.) or a few years later (b.) as indicated by the dashed arrow. The long-term average (e.g. 10-year average) is highlighted by a light blue oval for incidence, and by a light green oval for prevalence. The short-term average (e.g. 3-year average) is represented by a dark blue oval for incidence and purple oval for prevalence.

The undiscounted average burden of Campylobacter spp.
(a) and Salmonella spp. (b) in the Netherlands (average of 2005–2007) in DALY per year, subdivided in YLL and YLD for acute illness, sequelae and total. The 95% uncertainty range is shown using error bars.
Figure 4.
The undiscounted average burden of Campylobacter spp. and Salmonella spp.
in the Netherlands (average of 2005–2007) in DALY per year, for base case and scenario analysis. DALY are subdivided in YLL and YLD for actue illness, sequelae and total. The 95% uncertainty range is shown using error bars. Note: “Base case” represents a situation where only severe GE cases are at risk to develop reactive arthritis (ReA). “SA: ReA” represents the scenario analysis where all GE cases are at risk to develop ReA.
