A DURHAM University scientist says the world needs to be alert to the increased threat of mosquito-transmitted diseases.
Professor Steve Lindsay said 40 per cent of the world’s population is at risk from diseases such as malaria, dengue, Lyme disease and yellow fever, due to environmental changes.
He said travellers from the UK to the tropics and some European countries could be at risk from these often life-threatening diseases if they do not take the necessary precautions.
Professor Lindsay, from Durham University’s School of Biological and Biomedical Sciences, said: “Hundreds of millions of people are at risk from diseases such as malaria and dengue, along with other diseases which can cause a huge impediment to development or in some cases, death.
“The world is continually changing and we are seeing vectors moving to new areas.
“Governments and health organisations, and individuals, need to be alert to these changes.”
