The principal symptoms of dengue are:
High fever and at least two of the following:-
DENGUE FEVER PREVANTION
High fever and at least two of the following:-
- Severe headache
- Severe eye pain (behind eyes) joint pain
- Muscle and/or bone pain
- Rash
- Mild bleeding manifestation (e.g., nose or gum bleed, petechiae, or easy bruising)
- Low white cell count
Watch for warning signs as temperature declines 3 to 7 days after symptoms began. Go immediately to closest hospital, if any of the following warning signs appear:
- Severe abdominal pain or persistent vomiting
- Red spots or patches on the skin
- Bleeding from nose or gums
- Vomiting blood
- Black, tarry stools (feces, excrement)
- Drowsiness or irritability
- Pale, cold, or clammy skin
- Difficulty breathing
DENGUE FEVER PREVANTION
- Cover all water tanks, barrels and storage container with tightly fitted covers or with wire mesh 18 squares to the inch.
- Flower pots saucers and vases should be emptied and scrubbed at least once a week to destroy mosquito eggs. Eggs can hatch in to larvae in 3-6 days.
- Cut down and remove all bushes and clear overgrown lotsthat can harder mosquitoes.
- Keep guttering clear of leave and other debris.
Aedes mosquitoes typically live indoors and are often found in dark, cool places such as in closets, under beds, behind curtains, and in bathrooms. The risk of being bitten is highest during the early morning, several hours after daybreak, and in the late afternoon before sunset. However, mosquitoes may feed at any time during the day.

DENGUE FEVER
Dengue fever, also known as breakbone fever, is a mosquito-borne tropical disease caused by the dengue virus. Symptoms include fever, headache,muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.
Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti. The virus has five different types infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. As there is no commercially available vaccine, prevention is sought by reducing the habitat and the number of mosquitoes and limiting exposure to bites.
Treatment of acute dengue is supportive, using either oral or intravenous rehydration for mild or moderate disease, and intravenous fluids and blood transfusion for more severe cases. The number of cases of dengue fever has increased dramatically since the 1960s, with between 50 and 528 million people infected yearly. Early descriptions of the condition date from 1779, and its viral cause and transmission were understood by the early 20th century. Dengue has become a global problem since the Second World War and is endemic in more than 110 countries. Apart from eliminating the mosquitoes, work is ongoing on a dengue vaccine, as well as medication targeted directly at the virus.
