Tick maps

The tick maps are published regularly to provide the ECDC stakeholders, the scientific community and the general public with updated information on tick distribution at ‘regional’ administrative unit level (NUTS3 or equivalent and NUTS2 in Austria, Belgium, Denmark, Germany, The Netherlands, England (UK), Scotland (UK) and Wales (UK)). 

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 reticulatusHyalomma marginatumIxodes persulcatusIxodes ricinus, Rhipicephalus bursa, Rhipicephalus 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.

Submit data

ECDC and EFSA continue to improve the data collection for the maps. Data on the distribution of mosquito, tick, sand fly and culicoides vectors can be submitted to the common database through the VectorNet tool.
