Aware of Dengue!!!

The disease manifests as fever of sudden onset associated with headache, muscle and joint pains, distinctive retro-orbital pain, and rash.
The classic dengue rash is a generalised maculopapular rash with islands of sparing. A hemorrhagic rash of characteristically bright red pinpoint spots, known as petechiae can occur later during the illness and is associated with thrombocytopenia. It usually appears first on the lower limbs and the chest; in some patients, it spreads to cover most of the body. There may also be severe retro-orbital pain, (a pain from behind the eyes that is distinctive to Dengue infections), and gastritis with some combination of associated abdominal painnauseavomitingcoffee-grounds-like congealed blood, or severe diarrhea.
Some cases develop much milder symptoms which can be misdiagnosed as influenza or other viral infection when no rash or retro-orbital pain is present. Febrile travelers from tropical areas may transmit dengue inadvertently to previously Dengue free populations of Aedes (Stegomyia) aegypti mosquitoes, having not been properly diagnosed for Dengue. Patients only transmit Dengue when they are febrile and bitten by Aedes (Stegomyia) aegypti mosquitoes, or (much more unusually) via blood products.
The classic dengue fever lasts about two to seven days, with a smaller peak of fever at the trailing end of the disease (the so-called "biphasic pattern"). Recovery may be associated with prolonged fatigue and depression. Clinically, the platelet count will drop until after the patient's temperature is normal.
Cases of DHF also show higher fever, variable hemorrhagic phenomena including bleeding from the eyes, nose, mouth, ear, into the gut, and oozing of blood from skin pores,thrombocytopenia, and hemoconcentration. When Dengue infections proceed to DHF symptoms, DHF causes vascular leak syndrome which includes fluid in the blood vessels leaking through the skin and into spaces around the lungs and abdomen. This fluid loss and severe bleeding can cause blood pressure to fall; then Dengue Shock Syndrome (DSS) sets in, which has a high mortality rate.
Neurological manifestations such as encephalitis may also occur .
Some others said drinks 
-Bitter Gourd Soup
-Watermelons juice
-papaya leaf juice 
they said those will be helpful for the dengue victims to recover. (just for reference)
