In this article, we will discuss the Definition of Dengue Hemorrhagic Fever. So, let’s get started.
Dengue hemorrhagic fever is characterized by all manifestations of classical dengue fever, thrombocytopenia, vascular instability, and increased permeability resulting in leakage of intravascular fluid to interstitial space (hemoconcentration) and local hemorrhage (positive tourniquet test, spontaneous petechiae, and/or purpura) or frank hemorrhage (epistaxis, gum bleeding, bleeding into GI tract, i.e. melena or hematochezia) have been described. The hemorrhage is inconstant and is thought to be a combined effect of vascular damage and thrombocytopenia.
As the plasma leakage increases, patient may become restless, irritable, and develops hypotension and shock (cold extremities) called dengue shock syndrome (DSS). In severe cases, frank shock is present with low pulse pressure (<20 mmHg), cyanosis, hepatomegaly, pleural effusion, and ascites. In some cases, severe ecchymosis and GI bleeding may be seen.
In this article we will discuss about sign and symptoms of dengue fever and what possible preventive measures we should adopt in order be safe from this debilitating disease.
General Dengue Fever includes following symptoms:
Pain behind the eyes
High Grade Fever
Majoritypopulation recover within a week or so but some cases it results in a more severe form called dengue haemorrhagic fever.
Dengue Haemorrhagic Fever shows following symptoms:
Severe abdominal pain
Bleeding gums or epistaxis i.e bleeding from nose
Blood in urine, stools or vomit
Petechiae or Ecchymosis i.e bleeding under skin
Difficult or rapid breathing
Cold or clammy skin (shock)
Stay away from heavily populated or overcrowded places.
Use mosquito repellents, even in indoors like mosquito repellent roll-ons,creams etc.
Wear long-sleeved shirts and long pants tucked into socks in outdoors.
