2.  Dengue fever is a disease caused by
a family of viruses that are
transmitted by mosquitoes. It is an
acute illness of sudden onset that
usually follows a benign course with
symptoms such as
headache, fever, exhaustion, severe
muscle and joint pain, swollen
glands (lymphadenopathy), and
rash.

3.  Dengue (pronounced DENG-
gay) can affect anyone but
tends to be more severe in
people with compromised
immune systems. Because it is
caused by one of four
serotypes of virus, it is possible
to get dengue fever multiple
times.

4. Dengue goes by other
names, including "breakbone"
or "dandy fever." Victims of
dengue often have contortions
due to the intense joint and
muscle pain, hence the name
breakbone fever.

5.  Dengue hemorrhagic fever is a more severe
form of the viral illness. Symptoms include
headache, fever, rash, and evidence of
hemorrhage in the body. Petechiae (small
red or purple splotches or blisters under
the skin), bleeding in the nose or
gums, black stools, or easy bruising are all
possible signs of hemorrhage. This form of
dengue fever can be life-threatening and
can progress to the most severe form of
the illness, dengue shock syndrome.

6. Dengue fever facts:
 Dengue fever is a disease caused by a family
of viruses that are transmitted by
mosquitoes.
 Symptoms such as
headache, fever, exhaustion, severe joint and
muscle pain, swollen glands
(lymphadenopathy), and rash. The presence
(the "dengue triad") of fever, rash, and
headache (and other pains) is particularly
characteristic of dengue fever.

7.  Because dengue fever is caused by a virus, there
is no specific medicine or antibiotic to treat it. For
typical dengue fever, the treatment is purely
concerned with relief of the symptoms
(symptomatic).
 Dengue hemorrhagic fever (DHF) is a specific
syndrome that tends to affect children under 10
years of age. It causes abdominal pain,
hemorrhage (bleeding), and circulatory collapse
(shock).
 The prevention of dengue fever requires control or
eradication of the mosquitoes carrying the virus
that causes dengue.

8.  Dengue is prevalent throughout the
tropics and subtropics. Outbreaks
have occurred recently in the
Caribbean, including Puerto
Rico, the U.S. Virgin
Islands, Cuba, and Central
America.

9.  In 2011, Bolivia, Brazil, Columbia, Costa
Rica, El
Salvador, Honduras, Mexico, Peru, Puerto
Rico, and Venezuela reported a large
number of dengue cases. Paraguay
reported a dengue fever outbreak in
2011, the worst since 2007.
 The U.S. Centers for Disease Control and
Prevention (CDC) reports that from 1946 to
1980, no cases of dengue acquired in the
continental United States were reported..

10.  A 2009 outbreak of dengue fever in Key
West, Fla., showed that three patients
who did not travel outside of the U.S.
contracted the virus. Subsequent
testing of the population of Key West
has shown that up to 55 of the people
living in the area have antibodies to
dengue. In total, 28 people were
diagnosed with dengue fever in this
outbreak.

11. Dengue fever is common, in
at least 100 countries in
Asia, the Pacific, the
Americas, Africa, and the
Caribbean.
Thailand, Vietnam, Singapor
e, and Malaysia have all
reported an increase in
cases.

12.  The virus is contracted from the bite of
a striped Aedes aegypti mosquito that
has previously bitten an infected
person. The mosquito flourishes during
rainy seasons but can breed in water-
filled flower pots, plastic bags, and
cans year-round. One mosquito bite can
cause the disease.

13.  After being bitten by a mosquito
carrying the virus, the incubation period
ranges from three to 15 (usually five to
eight) days before the signs and
symptoms of dengue appear in stages.
Dengue starts with chills, headache,
pain upon moving the eyes, and low
backache

14.  .
Painful aching in the legs and joints
occurs during the first hours of illness.
The temperature rises quickly as high as
104 F (40 C), with relatively low heart rate
(bradycardia) and low blood pressure
(hypotension). The eyes become
reddened. A flushing or pale pink rash
comes over the face and then
disappears.

15.  The diagnosis of dengue fever is usually
made when a patient exhibits the typical
clinical symptoms of headache, fever, eye
pain, severe muscle aches and petechial rash
and has a history of being in an area where
dengue fever is endemic. Dengue fever can
be difficult to diagnose because its
symptoms overlap with those of many other
viral illnesses, such as West Nile virus and
chikungunya fever.
