Salmonellosis - Just the tip of the iceberg
Salmonella infections are among the most common food-borne infections affecting humans in the EU. However, the reported case numbers are much lower than the actual number of circulating infections. ECDC's seroincidence tool estimates the frequency of exposure to Salmonella, which is much closer to the true incidence of Salmonella in the population than the reported number.
Seroincidence calculator tool
The seroincidence calculator utilises the combination of serum antibody levels (lgG, lgM, and lgA) at a given point in time to estimate the time since seroconversion, which in turn gives an estimate of annual 'force of infection' in the tested population.
