Dengue fever, the outcome of the bite of an Aedes mosquito, is caused by viruses that are closely related to those that give you West Nile and yellow fever. So, the symptoms can be quite confusing at times. One starts experiencing the symptoms of dengue four to six days after the infection. They may last for more than 10 days. Young kids and people suffering from dengue for the first time go through mild symptoms while older children and adults, especially those who have been attacked by the condition more than once, are likely to experience severe manifestations.
This mosquito-borne disease manifests itself through high fever, skin rashes (they appear two to five days after the fever sets in), severe headache accompanied by joint and muscle pain, vomiting, mild bleeding in nose and gums, etc.
If left untreated, the symptoms may worsen and can be even fatal. In extreme cases, dengue symptoms may lead to dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). DHF leads to abnormally high fever, damage in the lymph and blood vessels, nose and gum bleeding, enlarged lever and circulatory system failure. When these symptoms intensify, internal bleeding becomes massive and the patient experiences shock. This condition is known as DSS, which may lead to death.
