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.

Surveillance for ticks

The surveillance maps shows the regions where surveillance activities for ticks were held in Europe and neighbouring regions.

Distribution maps of ticks

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 lusitanicum, Hyalomma marginatum, Ixodes persulcatus, Ixodes ricinus, Ornithodoros erraticus, Rhipicephalus sanguineus.

For native species the possible distribution statuses are:

  • Present: The species has been observed to be present in at least one municipality within the administrative unit.
  • Introduced: The species has been introduced in the administrative unit without confirmed establishment.
  • Anticipated Absent: the species has never been reported and there is a high probability that it is absent.
  • Confirmed Absent: the species has never been reported within the administrative unit 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: The status is unknown

Areas outside the scope of the VectorNet geographical scope are colour-coded as ‘Outside scope’.

Vector distribution status changes in terms of spatial units since the previous update

Since the previous update (August 2023), updates for the seven species are as follows:

  • Dermacentor reticulatus: data captured for 5 NUTS3s, with no changes suggested for any NUTS3s
  • Hyalomma lusitanicum: data captured for 6 NUTS3s, with no changes suggested for any NUTS3s
  • Hyalomma marginatum: data captured for 8 NUTS3s, and changes suggested for 2 NUTS3 – including new areas of presence in Algeria and Tunisia
  • Ixodes persulcatus: no new data captured for this reporting period 
  • Ixodes ricinus: data captured for 128 NUTS3s, and changes suggested for 3 NUTS3s – including new areas of presence in Croatia, France and Spain 
  • Ornithodoros erraticus: no new data captured for this reporting period 
  • Rhipicephalus sanguineus: data captured for 10 NUTS3s, and changes suggested for 4 NUTS3s – including new areas of presence in Spain (northern Spain and Tenerife) and Western Sahara.
