Current status of invasive mosquito surveillance in the UK.

Vaux AG, Medlock JM - Parasit Vectors (2015)

Bottom Line: There is no evidence to date that any invasive Aedes species (e.g., Aedes albopictus, Aedes japonicus, Aedes aegypti) occur in the UK despite sharing many of the same routes that have been found to have facilitated their entry into other countries.This paper sets in context the UK approaches with other European countries and those recommended by the ECDC.It also highlights future UK strategies to enhance surveillance for non-native mosquitoes to help ensure that incursions can be managed, and these mosquitoes do not establish and public health is protected.

ABSTRACT

Background: Non-native invasive mosquitoes have for many years made incursions into Europe, and are now established in many European countries. The continued European importation of potential vectors and their expansion within Europe increases their potential for importation and establishment in the UK. Coupled with increasing numbers of returning dengue and chikungunya infected travellers, the potential exists for transmission of vector borne disease in new regions.

Methods: To ensure a cost-effective risk assessment and preparedness strategy the UK employs a multi-faceted approach to surveillance for non-native Aedes mosquitoes, including passive and active surveillance strategies at a local, regional, and national level. Passive surveillance, including a national mosquito recording scheme and local authority nuisance biting reporting, are combined with targeted active surveillance at seaports, airports, used tyre importers, and motorway service stations.

Results: There is no evidence to date that any invasive Aedes species (e.g., Aedes albopictus, Aedes japonicus, Aedes aegypti) occur in the UK despite sharing many of the same routes that have been found to have facilitated their entry into other countries.

Conclusions: This paper sets in context the UK approaches with other European countries and those recommended by the ECDC. It also highlights future UK strategies to enhance surveillance for non-native mosquitoes to help ensure that incursions can be managed, and these mosquitoes do not establish and public health is protected. Focus will be given to increasing the number of submissions of mosquitoes to passive surveillance schemes and maintaining active surveillance efforts at key routes of potential importation.

Mentions: The port mosquito survey was started in 2010 and where possible mosquito surveillance continued over the subsequent years. No invasive mosquitoes have so far been recorded, and of the six native species that were recorded during the intensive survey in 2010, all are widespread and abundant throughout the majority of the UK (Culex pipiens s.l., Anopheles claviger, Culiseta annulata, Anopheles maculipennis s.l., Ochlerotatus detritus, and Coquilletidia richiardii). The main aim of the project was to facilitate each PHO to identify the optimal surveillance technique for their seaport / airport, particularly regarding operationally intensive areas surrounding aircraft and container movements (Fig. 5). BG Sentinel traps provided a useful and efficient method of monitoring adult mosquitoes in sheltered areas such as imported goods warehouses, with ovitraps used in key locations around cargo areas. Mosquito Magnets continue to be used at Liverpool seaport, and BG Sentinels have also had further use at Felixstowe Border Inspection Post (BIP) where food and other produce imports are inspected. The project identified a number of key areas where further efforts are required including: a focus on the importation of used tyres and development of a database that tracks the movement of these goods; continued reporting of nuisance biting to the Mosquito Recording Scheme; and capacity building to apply control regimes in the event of finding an invasive species.Fig. 5
