Leukopenia is frequently found and may be accompanied by varying degrees of thrombocytopenia. Normal platelet counts are betweentoIf a clinical diagnosis is made early, a health care provider can effectively treat DHF using fluid replacement therapy.
Clinical presentation of DF and the early phase of DHF are similar, and therefore it can be difficult to differentiate between the two forms early in the course of illness. When the fever declines, warning signs may develop. For more detailed guidance on management for DF please see the recommended treatment courses for DHF in the links listed below.
Symptoms of dengue hemorrhagic fever include: Once a patient experiences frank shock he or she will be categorized as having DSS. The Convalescent Reabsorption Phase: Signs of plasma leakage appear as increased fluid accumulation in the chest and abdominal cavity known as pleural effusion or ascites respectively.
While no therapeutic agents exist for dengue infections, the key to the successful management is timely and judicious use of supportive care, including administration of isotonic intravenous fluids or colloids, and close monitoring of vital signs and hemodynamic status, fluid balance, and hematologic parameters.
Serological testing for anti-dengue IgM antibodies or molecular testing for dengue viral RNA or viral isolation can confirm the diagnosis, but these tests often provide only retrospective confirmation, as results are typically not available until well after the patient has recovered.
Mild bleeding manifestation e. Usually, the blood of the patient is tested for the presence of antibodies and virus. However, it is not transmitted directly from person-to-person. Treatments such as intravenous fluid replacement should be administered to these patients to prevent shock.
Modifying the rate and volume of intravenous fluids and often times discontinuing intravenous fluids altogether to avoid fluid overload as the extravasated fluids return to the intravascular compartment is important. Warning signs that may occur at or after defervescence the presence of one or more of these signs indicates the need for immediate medical evaluation Abdominal pain or tenderness Clinical fluid accumulation i.
Green leafy vegetables It is advisable to consume more green leafy vegetables in order to fight dengue virus. Once you are infected with one of the viruses, you develop immunity to that virus for the rest of your life.
Complications that arise during Convalescent Reabsorption Phase are frequently related to the intravenous fluid management. Dengue often causes symptoms that are similar to other diseases such as flu, measles, and typhoid fever etc. The Febrile Phase: In the case of more serious complications such as dengue hemorrhagic fever, the following diagnosis must be performed: It is possible to be infected with all four different types of the dengue virus in your lifetime.
Patients should drink plenty of fluids, as dehydration is common among those affected with Dengue. This may lead to failure of the circulatory system and shock, and possibly death without prompt, appropriate treatment. As many as one half of all dengue infected individuals are asymptomatic, that is, they have no clinical signs or symptoms of disease.
They should also rest, drink plenty of fluids to prevent dehydration, avoid mosquito bites while febrile and consult a physician.
· Such warning signs indicate that the dengue infection may be serious and could progress to associated bleeding and organ failure, or what is called dengue hemorrhagic fever (DHF).
If one or more of the above symptoms are present, the subsequent hours of dengue infection could be lethal without proper hospital care%().
Dengue hemorrhagic fever can occur when someone is bitten by a mosquito or exposed to blood infected with the dengue virus. Infected mosquitoes are the most common causes.
Dengue hemorrhagic fever (DHF) is a severe, often fatal, febrile disease caused by dengue viruses characterized by abnormalities of hemostasis and capillary permeabil- ity that leads, in severe. 3 Frequently Asked Questions on Dengue infected with one or more types of dengue virus are thought to be at greater risk for developing dengue haemorrhagic fever if infected again.
Dengue virus is spread in tropical areas of the world and is the causative agent of dengue fever and dengue hemorrhagic fever. It is horizontally transmitted to humans by infected Aedes mosquitoes. Since the second edition of Dengue haemorrhagic fever: diagnosis, treatment, prevention and control was published by the World Health Organization (WHO) inthe magnitude of the dengue problem has increased dramatically and has extended.
