National surveillance system of arboviral diseases: regular bulletins

In Italy, specific surveillance plans are in place for the following arboviral diseases: Chikungunya, Dengue, Zika, West Nile, Usutu, Tick-borne encephalitis (TBE) and neuroinvasive infections caused by Toscana virus.


The integrated surveillance of arboviral diseases in Italy is coordinated by the Istituto Superiore di Sanità (ISS) and (for the West Nile and Usutu viruses) the Istituto Zooprofilattico of Abruzzo and Molise (Izs-AM), in collaboration with the Ministry of Health, which regularly publishes surveillance and response plans to ensure early detection of potential cases and minimize any spread of disease.


In evidenza

Between 1 January and 31 December 2021, the national surveillance system recorded:

  • 18 confirmed cases of neuroinvasive infection - TBE (14 local cases and 4 linked to a trip abroad, with a median age of 52 years; 67% males; no deaths)
  • 11 confirmed cases of Dengue (all linked to trips abroad, with a median age of 34 years; 90% males; no deaths)
  • 56 confirmed cases of infection with Toscana virus (only local cases, with a median age of 52 years; 71% males; no deaths)
