Dengue Symptoms and Preventions


Dengue fever is caused by mosquito bites. When a mosquito bites a person infected with a dengue virus, the virus enters the mosquito. Then, when the infected mosquito bites another person, the virus enters that person's bloodstream and causes an infection. The mosquito that causes Dengue fever is called Aedes Aegypti that has classic white spots. It takes 4 to 10 days before the symptoms appear. It causes fever and body pain in mild cases and in severe infection it causes hemorrhagic fever needing hospitalisation.

The following are the common symptoms

  •   High fever  around 104 F temperature
  •   Headache
  •   Muscle, bone or joint pain
  •   Nausea
  •   Vomiting
  •   Pain behind the eyes
  •   Rash on the face and body which appears on day three. It starts itching with small red and bumpy patches (maculopapular) and stays for a few days.


Dengue fever is diagnosed by performing a special test called NS 1 Dengue and basic blood count in which the platelets tend to decrease.The majority of the patients tend to develop mild symptoms that resolve within a week. PANADOL is given for fever and body pains, AVOID NSAIDS( painkillers) or BRUFEN as that will further decrease the level of platelets. Take plenty of fluids. Avoid brushing your teeth and stay away from sharp objects. The magic potion here is PAPAYA LEAF EXTRACT. Wash the leaves, put some water and grind it. Have a teaspoonful twice a day.


Platelets need to be monitored if fall below 10,000(normal range is 150,000 to 400,000) needs admission and platelets need to be transfused to prevent bleeding.


The only prevention is to avoid mosquito bites, drain fresh water lying in any open container. Wear full sleeve clothes, apply mosquito repellants and patches. Mosquito repellent patch contains plant citronella oils, mild and non-irritating, long-lasting mosquito repellent, specially designed for women, infants and young children. Place nettings on doors and windows. Spray mosquito killing sprays.
