In Abruzzo, health officials initially reported that there was no emergency regarding the West Nile Virus despite two confirmed human infections. Regional authorities emphasized that a sanitary protocol and a monitoring network involving the Health Department and local health authorities were sufficient to manage the virus, which was circulating in several Italian regions.

By late August, the situation in other regions, specifically Campania, showed more severe outcomes, including a death and several serious cases in the provinces of Naples and Caserta. In response, local officials in Aversa issued ordinances to combat mosquito proliferation by eliminating stagnant water. 

Concurrently, physicists at the University of Naples Federico II developed a mathematical model to predict epidemic waves. This model uses a quantum version of the ‘Game of Life’ to simulate interactions between humans and mosquitoes, correlating infection curves with temperature and humidity variations.
