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.

Tick surveillance effort over 2015–2019

The map Tick surveillance effort over 2015–2019' shows the surveillance effort per administrative area, by highest surveillance type.

Seasonal active surveillance for ticks over 2017–2019

The map 'Seasonal active surveillance for ticks over 2017–2019' shows the number of different calendar months in which any active surveillance took place per administrative area.

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 reticulatusHyalomma marginatumIxodes persulcatusIxodes 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’.
