Standardized incidence ratio dataset of human West Nile Virus in Italy (2012-2024)

West Nile virus (WNV) is primarily transmitted by Culex pipiens mosquitoes
feeding on infected birds, while humans and other mammals serve as
dead-end hosts. Although first detected in horses in Italy in 1998, human
cases only emerged after the implementation of a multispecies surveillance
program in 2001, with a major outbreak occurring in 2008 in northern
regions. In this dataset, we computed the Standardized Incidence Ratio
(SIR) for human West Nile virus (WNV) cases at the provincial level in
Italy over the period 2012–2024. The data are provided in a CSV file,
where each row corresponds to a province that reported at least one
confirmed case during the study period, and each column contains annual
SIR values. Provinces with no reported cases in a given year are marked as
NA. Additionally, for each province, we calculated summary statistics
including the temporal gradient, mean, standard deviation, maximum, and
minimum SIR values, based on the available data.
