Climate Change Is Expanding Mosquito Ranges and Disease Risks
- Climate change is driving the expansion of mosquito ranges into historically temperate regions, including New England, according to reporting from Ars Technica.
- In Connecticut, a statewide mosquito monitoring program has identified 54 different species.
- The migration of the Asian tiger mosquito is a primary concern for public health officials because the species can transmit several serious illnesses.
Climate change is driving the expansion of mosquito ranges into historically temperate regions, including New England, according to reporting from Ars Technica. This shift increases the risk of diseases like dengue and Zika as invasive species move into warmer, wetter northern territories.
In Connecticut, a statewide mosquito monitoring program has identified 54 different species. This count includes the Asian tiger mosquito, an invasive species that typically thrives in hot and humid climates further south but is now establishing a presence in the state, Ars Technica reports.
Disease Risks from Asian Tiger Mosquitoes
The migration of the Asian tiger mosquito is a primary concern for public health officials because the species can transmit several serious illnesses. According to Ars Technica, these include dengue and Zika, both of which are more common in tropical regions but pose a growing threat as the mosquito’s range shifts north.
The expansion is linked to changing environmental conditions. Warmer temperatures and increased moisture in regions like New England create habitats that support these invasive insects, allowing them to survive and reproduce in areas where they previously could not.
