What is the infectious agent that causes Dengue?
How is Dengue spread?
Where is Dengue found?
The mosquitoes that transmit Dengue live among humans and breed in discarded tires, flower pots, old oil drums, and water storage containers close to human dwellings. Unlike the mosquitoes that cause malaria, Dengue mosquitoes bite during the day.
What are the signs and symptoms of Dengue fever and dengue hemorrhagic fever?
Most Dengue infections result in relatively mild illness, but some can progress to Dengue hemorrhagic fever. With Dengue hemorrhagic fever, the blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Bruising can be a sign of bleeding inside the body. Without prompt treatment, the blood vessels can collapse, causing shock (Dengue shock syndrome). Dengue hemorrhagic fever is fatal in about 5 percent of cases, mostly among children and young adults.
How soon after exposure do symptoms appear?
How is Dengue diagnosed?
Who is at risk for Dengue?
What is the treatment for Dengue and Dengue hemorrhagic fever?
There is no specific treatment for Dengue. Persons with Dengue fever should rest and drink plenty of fluids. They should be kept away from mosquitoes for the protection of others. Dengue hemorrhagic fever is treated by replacing lost fluids. Some patients need transfusions to control bleeding.
How common is Dengue?
Is Dengue an emerging infectious disease?
Several factors are contributing to the resurgence of Dengue fever:
· No effective mosquito control efforts are underway in most countries with Dengue.
· Public health systems to detect and control epidemics are deteriorating around the world.
· Rapid growth of cities in tropical countries has led to overcrowding, urban decay, and
substandard sanitation, allowing more mosquitoes to live closer to more people.
· The increase in non-biodegradable plastic packaging and discarded tires is creating new
· The increase in non-biodegradable plastic packaging and discarded tires is creating new
breeding sites for mosquitoes.
· Increased jet air travel is helping people infected with Dengue viruses to move easily from

Dengue hemorrhagic fever is also on the rise. Persons who have been infected with one or more forms of Dengue virus are at greater risk for the more severe disease. With the increase in all types of virus, the occurrence of Dengue hemorrhagic fever becomes more likely.
