Are Mosquitoes in the UK Dangerous?
WouterSeveral invasive species of mosquitoes have spread into the UK in recent years. These include the Asian tiger mosquito, which lays eggs in plants and transportable materials such as used vehicle tyres.
This species is capable of spreading dengue and chikungunya disease. It is considered a threat to the UK because of its ability to survive colder temperatures.
Climate change is believed to be a major contributory factor to the introduction of invasive species into the UK. Statistical niche models have been developed to estimate the suitability of the UK for Aedes albopictus. Currently, extreme model scenarios indicate that sustained transmission of malaria could occur in southern England by 2080.
Other diseases are also transmitted by mosquitoes. Most of these infections are mild, but it is possible to develop severe allergic reactions to an insect bite. The result may be large areas of itching and lesions. If you have been bitten, seek medical advice.
The UK is home to 30 species of native mosquitoes. The majority of these are not known to transmit infections. In the past, malaria carried by these mosquitoes was found in salt marshes of southeastern England. However, the outbreaks were limited.
The Asian tiger mosquito is an invasive species that is now present in 25 European countries. It has spread throughout southern Europe and has been recorded in two sites in the UK in recent years. It is able to resist colder winter temperatures and can lay eggs in plants and transportable materials.
