Tick maps

The vector distribution maps are published regularly on the website to provide the ECDC stakeholders and the general public with the most up-to-date information on vector distribution, showing the distribution of the vector species at ‘regional’ administrative level (NUTS3). 

Please note that the maps do not represent the official view or position of the countries. 

Tick species - Distribution maps

The map shows the current known distribution of the tick species in Europe at ‘regional’ administrative level (NUTS3). They are based on published historical data and confirmed data provided by experts from the respective countries as part of the VectorNet project.

Separate maps for the distribution of each of the following tick species are currently available:  Dermacentor reticulatus, Hyalomma marginatum, Ixodes persulcatus, Ixodes ricinus, Rhicephalus sanguineus, Ornithodoros spp

For native species the possible distribution statuses are:

  • Present: The species is known to have been present at least in one municipality within the administrative unit/study area.
  • Introduced: The species has been introduced in the administrative unit/study area without confirmed establishment.
  • Anticipated Absent: the species has never been reported and you estimate a high probability of absence.
  • Confirmed Absent: the species has never been reported within the administrative unit/study area and there have been field surveys or studies on ticks within the last 5 years of the distribution status date.
  • No Data: No sampling has been performed and no data on the species is available.
  • Unknown: It is unknown whether there are field studies on this species.

Join VectorNet and submit data

ECDC and EFSA, through the VectorNet network, continues to improve the data collection for the maps. VectorNet is looking for vector-borne disease experts who are interested in sharing data on the distribution of mosquito, tick, sand fly and culicoides vectors. Experts can contact VectorNet at VectorNet@ecdc.europa.eu  to join the network. They can also register and upload data to the common database through the VectorNet tool. 


VectorNet tool


The VectorNet tool is an online tool where external experts in vectors and vector-borne diseases can submit information on the distribution of vectors like ticks, mosquitoes, sand flies and biting midges in Europe. Experts that wish to contribute can register and submit data at various administrative scales (NUTS 1-2-3) or data linked to geographic coordinates. They can insert directly their data in an online database.
