Britain's warmer weather to bring deadly tropical disease-carrying mosquitoes within YEARS

Scientists say diseases including dengue fever and the West Nile virus could become common as warmer weather attracts insects from parts of Asia and Africa.
The biggest threat to the UK comes from the Asian tiger mosquito, which spreads dengue fever and the chikungunya virus.
Both cause serious illnesses, which especially in the case of dengue fever can be fatal.
The latest Public Health England (PHE) data shows the number of Britons infected while on holiday with chikungunya increased 12-fold last year.
The disease can cause joint pain and arthritis lasting years.



Climate change projections suggest that a 2C rise in temperature could extend the insect’s activity season by one month and geographical spread by up to 30 per cent by 2030.
However the report’s authors add that climate change is not the only factor in bringing tropical diseases to Britain.
Professor Steve Leach, from the emergency responses department at PHE, said: "We are not suggesting that climate change is the only or the main factor driving the increase in vector-borne diseases in the UK and Europe, but that it is one of many factors including socio-economic development, urbanisation, widespread land-use change, migration, and globalisation that should be considered.
"Lessons from the outbreaks of West Nile virus in North America and chikungunya in the Caribbean emphasise the need to assess future vector-borne disease risks and prepare contingencies for future outbreaks."
Writing in the Lancet Infectious Diseases Journal, PHE scientists say there are already 34 different species of mosquito in the UK.
And all the evidence points to a rise in number of blood-sucking insects – including ticks – in parts of Europe.
