Dengue

In tropical and subtropical countries, the virus causing dengue is spiking. Close to an historic high of over 6 million cases and more than 7,000 dengue-related deaths were reported in over 80 countries and territories in 2023. Most places in Europe remain too cool to favour the mosquito or the virus, but imported dengue cases have been rising in the European region and the impact of climate change appears to be shifting the picture. 

To find out more about dengue and the family of viruses it belongs to, called arboviruses, Alice Allan speaks to Marc-Alain Widdowson, high threat pathogens technical lead at the WHO Regional Office for Europe and medical entomologist Luca Facchinelli. To learn more about Italy’s work on dengue prevention and communication, she speaks to Flavia Riccardo, an epidemiologist in the Infectious Disease Department of the Italian National Institute of Health, and her colleague from the Institute’s press office, Pier David Malloni.
