May 30, 2014 The odds are that a victim will recover. But the mosquito-borne virus can be incredibly painful. It's also a growing health concern around the globe and has even been spotted in the United States.

May 13, 2014 A malaria patient can carry different parasites that respond differently to drugs. Now there's a way to profile the parasites, which could someday lead to more tailored treatments.
Mosquitoes like thisÂ Aedes aegypti female can spread dengue fever.
October 17, 2013 It turns out that the mosquito-borne illness has been hanging around Houston longer than thought. A look at blood and spinal fluid samples collected from patients a decade ago found that quite a few of them had been sick with undiagnosed dengue fever.

October 2, 2013 Scientists have figured out how DEET repels mosquitoes. The finding has led the researchers to candidate repellents that are safer and cheaper than DEET and may provide new weapons against mosquito-borne scourges, such as malaria and dengue fever.

July 25, 2013 Dr. Roger Nasci, a mosquito expert at the Centers for Disease Control and Prevention, says you don't necessarily need repellent with a high percentage of DEET to keep the 'skeeters away. Repellent still works well in low doses, and so far mosquitoes aren't growing resistant to it.
Many criteria — from blood type to body temperature — can play a role in affecting who attracts mosquitoes.
July 12, 2013 If mosquitoes used Yelp, they might look for their next meal by searching nearby for a heavy-breathing human with Type O blood, sporting a red shirt and more than a smattering of skin bacteria. Preferably either pregnant, or holding a beer.

May 16, 2013 Scientists used a Dutch woman's dirty stocking to learn that mosquitoes infected with malaria find humans hard to resist. Like a fungus that turns ants into zombies, the parasite seems to change the behavior of the mosquitoes for its own benefit.
