Researchers have created genetically modified mosquitoes resistant to the Type 2 dengue fever virus, which infects 50 million people annually. The mosquitoes showed high levels of resistance and were able to reproduce, making them a promising tool for controlling mosquito-borne diseases.
A new study estimates that dengue fever costs over $13 million annually, equivalent to 940,000 lost workdays of output. A potential vaccine could offset 87% of treatment costs, reducing the economic burden on governments and households.
A new research project aims to introduce the Wolbachia bacteria into mosquitoes that carry the deadly dengue virus, reducing its lifespan and transmission. The five-year study, led by UQ, seeks to develop a cost-effective, self-perpetuating control strategy for large regional areas.
A novel mosquito control strategy using Mesocyclops crustaceans has proven effective in eradicating Aedes aegypti and reducing dengue fever cases in Vietnam. The approach involves inoculating large water storage containers with the crustaceans, targeting areas with high mosquito larva production.
Rising global temperatures could lead to the expansion of dengue fever's geographic range into temperate regions. The mosquito Aedes aegypti's larval size and adult frequency will increase with warmer temperatures, boosting disease transmission.
A 1998 study predicts that global warming will increase the potential transmission of dengue fever in temperate regions. The researchers used computer models to simulate climate change and found that a relatively small temperature rise can lead to an increase in epidemic potential, allowing for more efficient virus spread.
