LONDON: Scientists have warned that the climate change may accelerate the emergence of mosquito-borne diseases such as dengue fever virus, chikungunya, in the UK within the next few decades, insects such as mosquitoes and ticks transmits diseases , are on the rise and have spread into new territories across Europe over the past decade.

Dr Jolyon Medlock and professor Steve Leach stated in his Lancet Infectious Diseases journal, from the emergency response department at Public Health England warn that disease carrying mosquitoes could also become widespread at Britain within the next few decades, because the climate becomes increasingly mild. Warmer temperatures and more rainfall could provide ideal conditions for the Asian tiger mosquito , that spreads the viruses that cause dengue and chikungunya.

Climate change models predict suitable temperatures for 3 months in southeast England by 2071 and upto 1 month of chikungunya virus transmission in London by 2041, Previously, tropical and subtropical regions faced dengue transmission and was largely confine. Due to freezing the mosquito’s larvae and eggs are under temperature kill, but rising temperatures could enable a albopictus. Even just a 2C rise in temperature could extend the mosquito’s activity season by 1 month and geographical spread by up to 30% by 2030.mos
