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 marginatum, Ixodes persulcatus, Ixodes ricinus, Rhipicephalus bursa, Rhipicephalus sanguineus, Ornithodoros spp.
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 (March 2021), changes at the NUTS3 level were recorded in 45. Data on Ixodes ricinus continues to dominate the dataset, and during this period, no data were identified in relation to Ornithodoros erraticus.
Updates for the seven species are as follows:
- Dermacentor reticulatus: data captured for 27 NUTS3s, and changes suggested for 7 NUTS3s —including new areas of presence in Luxembourg, Romania, Russia and Ukraine
- Hyalomma lusitanicum: data captured for 2 NUTS3, and a change suggested for 1 NUTS3 —which is a new area of presence in Algeria
- Hyalomma marginatum: data captured for 16 NUTS3s, and changes suggested for 14 NUTS3s —including new areas of presence in Algeria, Italy, Tunisia and Turkey, introduced records in Hungary and the Netherlands and repeated detections of importation into Sweden via migratory birds
- Ixodes persulcatus: data captured for 8 NUTS3s, and changes suggested for 1 NUTS3 —including new areas of presence in Russia
- Ixodes ricinus: data captured for 122 NUTS3s, and changes suggested for 9 NUTS3s —including new areas of presence in Algeria, Croatia, Russia, Serbia and Tunisia
- Ornithodoros erraticus: no data captured for this species
- Rhipicephalus sanguineus: data captured for 27 NUTS3s, and changes suggested for 13 NUTS3s —including new areas of presence in Algeria, Egypt, Jordan, Tunisia, Turkey and Russia
