Background: Tunisia has experienced several West Nile virus (WNV) outbreaks since 1997. Yet, there is limited information on the spatial distribution of the main WNV mosquito vector Culex pipiens suitability at the national level.
Objectives: In the present study, our aim was to predict and evaluate the potential and current distribution of Cx.
Background: Bluetongue (BT), a vector-borne disease of wild and domestic ruminants, is responsible for severe economic losses in flocks. To reduce this impact, a surveillance and control plan was implemented in Tunisia. However, the epidemiological situation of BT remains incompletely understood, especially for the circulating serotypes.

- Bluetongue (BT) is a significant viral disease affecting ruminants, recently causing outbreaks in Tunisia during fall 2020, particularly in sheep and cattle.
- Major eco-climatic factors analyzed include day and night land surface temperatures, normalized difference vegetation index (NDVI), and rainfall, with results indicating specific thresholds for these variables that correspond to increased BT cases.
- The study emphasizes the need for an effective early warning surveillance program in high-risk areas, leveraging these identified eco-climatic risk factors to better predict BT outbreaks.
Article Synopsis
- * Three flocks of sentinel chickens were monitored in different regions (Sejnene, Moknine, Tozeur) from September 2016 to January 2017 to check for WNV antibodies and viral RNA.
- * The study found a WNV positive rate of 10.7% in Sejnene and 9.8% in Tozeur, with two chickens testing positive for the virus; this shows the use of poultry is effective for monitoring WNV transmission.
West Nile virus (WNV) is an arthropod borne virus of public health importance. The virus is a member of the genus Flavivirus and belongs to the Japanese encephalitis virus (JEV) antigenic complex under the Flaviviridae family. The WNV is continuously spreading across Tunisia especially in the coastal and Southern area of the country.

The aim of this study was to provide the first serological investigation of four emerging vector-borne diseases in two groups of dromedaries in Tunisia. Sera were tested by ELISA and serum neutralisation test to identify West Nile virus (WNV), bluetongue virus (BTV), epizootic haemorrhagic disease virus (EHDV) and Rift Valley fever virus (RVFV).
