Climate change could trigger the spread mosquito-borne diseases

By RockedBuzz 2 Min Read

Climate change could trigger the spread of potentially fatal mosquito-borne diseases such as dengue fever to parts of Africa that are currently unaffected, study shows. 

Climate change could trigger the spread of mosquito-born diseases around Africa and beyond, study suggests.

What does climate change have to do with spreading disease?

For these reasons, the term “climate change” is now preferred over the term “global warming.” Because of rising temperatures and changing rainfall patterns, climate change is expected to have a substantial effect on the burden of infectious diseases that are transmitted by insect vectors and through contaminated water.

How does climate change affect Vector Borne Diseases?

Long-term anthropogenic climate change interacts with natural variability, influencing vectorborne disease transmission from shorter (e.g. annual) to longer (e.g. decadal) time scales, with variable effects at different times and in different locations.

 Climate change could trigger the spread of mosquito-born diseases.

Mosquito-borne diseases or mosquito-borne illnesses are diseases caused by bacteria, viruses or parasites transmitted by mosquitoes. Nearly 700 million people get a mosquito-borne illness each year resulting in over one million deaths.[1]

Diseases transmitted by mosquitoes include malariadengueWest Nile viruschikungunyayellow fever,[1] filariasistularemiadirofilariasisJapanese encephalitisSaint Louis encephalitisWestern equine encephalitisEastern equine encephalitis,[2] Venezuelan equine encephalitisRoss River feverBarmah Forest feverLa Crosse encephalitis, and Zika fever,[2] as well as newly detected Keystone virus and Rift Valley fever. There is no evidence as of April 2020 that COVID-19 can be transmitted by mosquitoes, and it is extremely unlikely this could occur.[3][4] Also HIV/AIDS is not transmittable through mosquito contact, despite being caused by a virus that can be transmitted through blood.[5]
