DENGUE FEVER ART
With more than one-third of the world’s population living in areas at risk for transmission, dengue infection is a leading cause of illness and death in the tropics and subtropics. As many as 100 million people are infected yearly.

BUG BITING
Malaria is a mosquito-borne disease caused by a parasite. People with malaria often experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die.
-
TINY BUT DEADLY
Each year 350-500 million cases of malaria occur worldwide, and over one million people die, most of them young children in sub-Saharan Africa.

DENGUE IN A MICROSCOPE
Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus (DENV) and the most effective protective measures are those that avoid mosquito bites.
-
SERIOUS BUGS
Infected mosquitoes spread West Nile virus that can cause serious, life-altering, and even fatal disease. Keep using insect repellent, wear long sleeves and long pants and dump out standing water in the yard where mosquitoes can lay their eggs.
-
OUCH!
Arthropod-borne viruses, i.e., arboviruses, are viruses that are maintained in nature through biological transmission between susceptible vertebrate hosts by blood feeding arthropods (mosquitoes, psychodids, ceratopogonids, and ticks). Vertebrate infection occurs when the infected arthropod takes a blood meal.

YELLOW FEVER
There is no specific treatment for yellow fever; care is based on symptoms. Illness ranges in severity from a self-limited febrile illness to severe hepatitis and hemorrhagic fever.

SWARM
Only female mosquitoes bite; using proteins from a blood meal to produce eggs. Most species can produce several batches of eggs during their lifetime. The mosquito's visual picture, produced by various parts of its body, is an infrared view produced by its prey's body temperature. The average life span of the female mosquito is 3 to 100 days; the male's is 10 to 20 days. Depending on species, female mosquitoes may lay 100 to 300 eggs at a time and may average 1,000 to 3,000 during their lifespan. Adults can live for several weeks, feeding on carbohydrate sources such as nectar and fruit juices. Worldwide, mosquito-borne diseases kill more people than any other single factor.
