The mosquito maps are published regularly to provide the ECDC stakeholders, the scientific community and the general public with updated information on the distribution and surveillance of the vector 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.
Invasive mosquitoes: Surveillance map
The surveillance map shows the regions where surveillance activities for exotic mosquitoes are ongoing in EU/EEA and the neighbouring countries. The surveillance activities include not only specific surveillance studies but also work done as part of on-going control activities, research projects and inventory studies.
Invasive mosquitoes: Distribution maps
The maps show the current distribution of invasive mosquito species in EU/EEA at ‘regional’ administrative unit level. The maps are based on data (published and unpublished) provided and validated by experts.
Separate maps for the distribution of each of the following exotic mosquito species are currently available: Aedes aegypti, Aedes albopictus, Aedes japonicus, Aedes atropalpus and Aedes koreicus.
For invasive species the possible distribution statuses are:
- Established: An established population (evidence of reproduction and overwintering) of the species has been observed in at least one municipality within the administrative unit.
- Introduced: The species has been detected (but without confirmed establishment) within the administrative unit.
- Absent: Field surveys or studies on mosquitoes were conducted but the species has not been detected within the administrative unit.
- No data: No sampling has been performed and no data on the species is available within the administrative unit.
- Unknown: It is unknown whether there are field studies on this species within the administrative unit.
Aedes koreicus - current known distribution: January 2019
Aedes aegypti - current known distribution: January 2019
Aedes atropalpus - current known distribution: January 2019
Aedes japonicus - current known distribution: January 2019
Native mosquitoes: Distribution maps
The maps show the current distribution of native mosquito species in Europe at ‘regional’ administrative unit level. The maps are based only on confirmed data (published and unpublished) provided by experts.
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.
