Climate change could expose 1 billion more people to bug-borne diseases, study says

(CNN)About a billion more people might be exposed to mosquito-borne diseases as temperatures continue to rise with climate change, according to a new study.

As the planet gets warmer, scientists say, diseases like Zika, chikungunya and dengue will continue spreading farther north.
The authors of the new study, published Thursday in the journal PLOS Neglected Tropical Diseases, created a model that includes data on predicted temperature changes and the known range of the day-biting, disease-carrying mosquitoes Aedes albopictus and Aedes aegypti.
    Europe will probably see some of the biggest increases in diseases from both of these species, the researchers say. The United States, East Asia, high-elevation parts of central America, East Africa and Canada will also see large increases in risk for these diseases.
      The much warmer climates in Southeast Asia and West Africa will not be as suitable for the albopictus species.
