CHART: Where Disease-Carrying Mosquitoes Will Go In The Future

NPR WUFT  online


Disease-bearing mosquitoes are on the move.Scientists have been pretty sure of that for decades. As temperatures rise in certain parts of the world, warmth-seeking mosquitoes will invade, making themselves at home in previously inhospitable patches of the globe.

A molecular surveillance-guided vector control response to concurrent dengue and West Nile virus outbreaks in a COVID-19 hotspot of Florida

The Lancet Regional Health-Americas

Heather Coatsworth, et. al


Simultaneous dengue virus (DENV) and West Nile virus (WNV) outbreaks in Florida, USA, in 2020 resulted in 71 dengue virus serotype 1 and 86 WNV human cases. We hypothesized that we would find a number of DENV-1 positive mosquito pools, and that the distribution of these arbovirus-positive mosquito pools would be associated with those neighborhoods for which imported DENV cases have been recently reported in 2019 and 2020.

A minimum data standard for vector competence experiments


Velen Yifei Wu, et. al


The growing threat of vector-borne diseases, highlighted by recent epidemics, has prompted increased focus on the fundamental biology of vector-virus interactions. To this end, experiments are often the most reliable way to measure vector competence (the potential for arthropod vectors to transmit certain pathogens).

Urban-adapted mammal species have more known pathogens

Nature Ecology & Evolution

Gregory F Albery, et. al


The world is rapidly urbanizing, inviting mounting concern that urban environments will experience increased zoonotic disease risk. Urban animals could have more frequent contact with humans, therefore transmitting more zoonotic parasites; however, this relationship is complicated by sampling bias and phenotypic confounders. Here we test whether urban mammal species host more zoonotic parasites, investigating the underlying drivers alongside a suite of phenotypic, taxonomic and geographic predictors.
