Dengue virus increases mosquito's lust for blood

Image
Mosquitoes are already blood-sucking machines, but new research indicates that the dengue virus, which the mosquitoes transmit to humans, makes them even thirstier for blood.

The virus specifically turns on mosquito genes that make them hungrier for a blood meal; the activated genes also enhance mosquitoes' sense of smell, something that likely improves their feeding skills. The result is a mosquito better able to serve the virus by carrying it more efficiently to human hosts.
