PARRILLA VALERO, Fernando  and  VAQUE RAFART, Josep. Incidence study of listeriosis in Spain. Gac Sanit [online]. 2014, vol.28, n.1, pp.74-76. ISSN 0213-9111.  https://dx.doi.org/10.1016/j.gaceta.2013.03.004.

We performed a descriptive retrospective study of cases of listeriosis occurring in Spain from 2001 to 2007 to determine the burden and trend of this disease in our setting. Several sources of information were used. Epidemiological information was collected from 1.242 cases of listeriosis, representing a mean incidence rate of 0,56 cases per 100.000 inhabitants per year, which was extrapolated as an overall estimate for Spain. The annual incidence showed a statistically significant increasing trend (p <0,001) over the study period. This figure was higher than that reported in Spain (0,16) by the Microbiological Information System, which is voluntary, showing that underreporting exists. The inclusion of listeriosis in the Mandatory Notification System would allow determination of the distribution and characteristics of this infection in humans, as well as promotion of effective prevention and control.
