Climate change is likely increasing cases of malaria in Kenya, various viral diseases in Australia’s outback, and tropical dengue fever in the U.S. “Widespread appearance of dengue in the continental United States is a real possibility,” write Dr. Anthony Fauci and Dr. David Morens in a commentary in the Journal of the American Medical Association. Climate change and poor efforts to control mosquito populations are contributors to the potential problem; in addition, write the doctors, “The combined effects of global urbanization and increasing air travel are expected to make dengue a growing international health problem for the foreseeable future.”
