Dengue fever

Dengue fever: Introduction

Dengue fever, also called dengue, is a potentially serious disease caused by a virus. There are four types of dengue virus that can cause illness in humans. Dengue viruses are transmitted between humans by the bite of an infected Aedes mosquito.

Dengue is rare in the U.S., but is common and a serious public health threat in warm sub-tropical and tropical areas of the world. These include areas of Central and South America, Africa, Southeast Asia, China, India, the Middle East, Australia, the Caribbean and the South and Central Pacific. Dengue fever is most common in urban areas and outbreaks occur commonly during the rainy season when mosquitoes breed heavily in standing water. The incidence of dengue fever is on the rise worldwide, and in some areas of Asia, complications of the disease are a leading cause of serious illness and death in children.

Mosquitoes pick up a dengue virus when they bite a human who is already infected with the virus. The mosquito then carries it in its own blood and spreads it when it bites other humans.

After a dengue virus enters the human bloodstream, it spreads throughout the body. Symptoms appear in about eight to ten days after a bite from an infected mosquito. Symptoms are flu-like and can include high fever, nausea, vomiting, body aches, and headache.

Most people can recover from dengue fever, but some cases can progress into a life-threatening complication called dengue hemorrhagic fever. Symptoms of this disease include severe, uncontrolled hemorrhage and shock. For more information on symptoms, refer to symptoms of dengue fever.

Making a diagnosis of dengue fever begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination. Recent travel to sub-tropical or tropical areas of the world is an important clue that may increase the suspicion of a diagnosis of dengue fever.

Diagnostic testing includes blood tests that check for a dengue virus or for antibodies that are produced by the body to fight a dengue virus.

A diagnosis of dengue fever can easily be missed or delayed in areas of the world, such as the U.S., where it is rare. For more information on misdiagnosis, refer to misdiagnosis of dengue fever.

There is no definite treatment for or vaccine to prevent dengue fever. Treatment of dengue fever includes getting plenty of rest, increasing fluid intake, and taking acetaminophen (Tylenol) for fever and body aches. For more information on treatment, refer to treatment of dengue fever. ...more »

Dengue fever: Treatments

The first step in treating dengue fever is prevention. Prevention measures include controlling mosquito populations in warm sub-tropical and tropical areas of the world. This includes draining areas and objects that can hold standing water and become a breeding ground for mosquitoes, such as old tires, puddles, and bird baths. Wearing insect repellent that contains ...more treatments »

Dengue fever: Misdiagnosis

A diagnosis of dengue fever can easily be missed or delayed in temperate or Northern areas of the world, such as the U.S., where it is rare. In addition, the symptoms of dengue fever, such as fever and body aches, closely resemble symptoms of influenza. If symptoms are mild, they may be overlooked or assumed to be due to a mild influenza infection. This may not become a ...more misdiagnosis »

Article Excerpts about Dengue fever

Dengue Fever: NIAID (Excerpt)

Dengue fever is an infectious disease carried by mosquitoes and caused by any of four related dengue viruses. This disease used to be called break-bone fever because it sometimes causes severe joint and muscle pain. Health experts have known about dengue fever for more than 200 years. (Source: excerpt from Dengue Fever: NIAID)

Dengue and Dengue Hemorrhagic Fever: Questions and Answers: DVBID (Excerpt)

Dengue (pronounced den' gee) is a disease caused by any one of four closely related viruses (DEN-1, DEN-2, DEN-3, or DEN-4). The viruses are transmitted to humans by the bite of an infected mosquito. In the Western Hemisphere, the Aedes aegypti mosquito is the most important transmitter or vector of dengue viruses, although a 2001 outbreak in Hawaii was transmitted by Aedes albopictus. It is estimated that there are over 100 million cases of dengue worldwide each year. (Source: excerpt from Dengue and Dengue Hemorrhagic Fever: Questions and Answers: DVBID)

Definitions of Dengue fever:

Acute infectious, eruptive, febrile disease caused by four antigenically related but distinct serotypes of the dengue virus; transmitted by the bite of infected Aedes mosquitoes, especially A. aegypti; classical dengue (dengue fever) is self-limiting and characterized by fever, myalgia, headache, and rash; dengue hemorrhagic fever is a more virulent form of dengue virus infection. - (Source - Diseases Database)
