Dengue Fever Symptoms, Prevention and Treatment
Dengue Fever
Dengue fever is a disease caused by a virus that is 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 and
rash.
Dengue strikes people with low levels of immunity.
Because it is caused by one of four serotypes of virus, it is possible to get
dengue fever multiple times. However, an attack of dengue produces immunity for
a lifetime to that particular serotype to which the patient was exposed.
Dengue haemorrhagic fever is a more severe form of the viral
illness. It is a specific syndrome that tends to
affect children under 10 years of age. It causes Manifestations include headache, fever, rash, and evidence of
hemorrhage in the body petechiae (small
red or purple blisters under the skin), bleeding from 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.
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 inflict the disease.
The virus is not contagious and cannot be spread directly from
person to person. There must be a person-to-mosquito-to-another-person pathway.
Symptoms :
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.
·
Dengue starts with
chills, headache, pain upon moving the eyes, and low back ache . 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 relative 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. The glands (lymph nodes) in the
neck and groin are often swollen.
·
Fever and other signs of
dengue last for two to four days, followed by a rapid drop in body temperature
(defervescence) with profuse sweating. This precedes a period with normal
temperature and a sense of well-being that lasts about a day.
·
A second rapid rise in
temperature follows. A characteristic rash appears along with the fever and
spreads from the extremities to cover the entire body except the face. The
palms and soles may be bright red and swollen.
Because dengue fever is caused by a virus, there is no specific
medicine or antibiotic to treat it. For typical dengue,the treatment is purely
concerned with relief of the symptoms (symptomatic). Rest and fluid intake for
adequate hydration is important
Prognosis:
Typical
dengue is fatal in less than 1% of cases. The acute phase of the illness with
fever and muscle aches lasts about one
to two weeks. Convalescence is accompanied by a feeling of weakness and full
recovery often takes several weeks.
Prevention:
1. The transmission of the virus to
mosquitoes must be interrupted to prevent the illness. To this end, patients
are kept under mosquito netting until the second bout of fever is over and they
are no longer contagious.
2. The prevention of dengue requires control
or eradication of the mosquitoes carrying the virus that causes dengue. Empty
stagnant water from old tires, trash cans, and flower pots.
3. To prevent mosquito bites, wear long pants
and long sleeves. For personal protection, use mosquito repellant sprays when
visiting places where dengue is endemic.
4. Limiting exposure to mosquitoes by
avoiding stagnation of water and staying indoors two hours after sunrise and
before sunset will help. The Aedes aegypti mosquito is a daytime biter
with peak periods of biting around sunrise and sunset. It may bite at any time
of the day and is often hidden inside homes or other dwellings
5. There is currently no vaccine available
for dengue fever.
