Dengue (DENG-gey) fever is a mosquito-borne disease that occurs in tropical and subtropical areas of the world. Mild dengue fever causes a high fever, rash, and muscle and joint pain. A severe form of dengue fever, also called dengue hemorrhagic fever, can cause severe bleeding, a sudden drop in blood pressure (shock), and death.

3. Dengue
(DENG-gey)
 Dengue (DENG-gey) fever is a mosquito-borne disease
that occurs in tropical and subtropical areas of the
world. Mild dengue fever causes a high fever, rash, and
muscle and joint pain. A severe form of dengue fever,
also called dengue hemorrhagic fever, can cause severe
bleeding, a sudden drop in blood pressure (shock) and
death.

4. Causes
 There are four dengue viruses (DENV) that cause
dengue fever. They are all spread by a species of
mosquito known as Aedes aegypti, and more rarely by
the Aedes albopictus mosquito.
 The viruses jumped from monkeys to humans
between 100 and 800 years ago Trusted Source,
according to the CDC, but dengue remained a minor
problem until the middle of the twentieth century.
 Aedes aegypti originated in Africa, but nowadays it is
found in tropical areas around the world, especially in
and around areas of human population.The virus is
transmitted from an infected mosquito to a human.

5. Causes
 A mosquito bites a person who is infected with the dengue
virus, and the virus is passed on when the mosquito bites
someone else.It it possible to have dengue fever more than
once. A second infection carries a higher risk of developing a
harsher form.

7. Denguehemorrhagicfever
(Signsandsymptoms)
Most people recover within a week or so. In some cases,
symptoms worsen and can become life-threatening. This can
cause a severe form of dengue fever, called dengue

 Bleeding under the skin, which might look like bruising
 Difficult or rapid breathing
 Cold or clammy skin (shock)
 Fatigue
 Irritability or restlessness

8. Diagnostic Testing
 Nucleic acid amplification tests (NAATs)
 Serologic tests
 IgG antibody testing

9. Treatment
 Acetaminophen (Tylenol, others) can alleviate pain and
reduce fever. Avoid pain relievers that can increase
bleeding complications — such as aspirin, ibuprofen
(Advil, Motrin IB, others), and naproxen sodium
(Aleve, others).
you may need:
 Supportive care in a hospital
 Intravenous (IV) fluid and electrolyte replacement
 Blood pressure monitoring
 Transfusion to replace blood loss

10. Prevention
 Stagnant water: The Aedes mosquito breeds in clean,
stagnant water. Checking for and removing stagnant
water can help reduce the risk.
 Clothing: Reduce the amount of skin exposed by wearing
long pants, long-sleeved shirts, and socks, tucking pant
legs into shoes or socks, and wearing a hat.
 Mosquito repellents: Use a repellent with at least 10
percent concentration of diethyltoluamide (DEET), or a
higher concentration for longer lengths of exposure. Avoid
using DEET on young children.
 Mosquito traps and nets: Nets treated with insecticide are
more effective, otherwise the mosquito can bite through
the net if the person is standing next to it. The insecticide
will kill mosquitoes and other insects, and it will repel
insects from entering the room.
 Door and window screens: Structural barriers, such as
screens or netting, can keep mosquitos out.

tropical areas, such as Central and South America,
parts of Africa, parts of Asia, the Caribbean, and the
Pacific.
 Central and South America
 the Caribbean
 tropical Asia, including Bangladesh, Indonesia, and
