Does DHF involve a Hemorrhagic Fever?
Some patients with dengue fever go on to develop dengue hemorrhagic fever (DHF), a severe and sometimes fatal form of the disease. Around the time the fever begins to subside (usually 3–7 days after symptom onset), the patient may develop warning signs of severe disease.
What is dengue hemorrhagic fever DHF?
DHF is primarily a disease of children under the age of 15 years, although it may also occur in adults (1, 32). It is characterized by sudden onset of fever, which usually lasts for 2 to 7 days, and a variety of nonspecific signs and symptoms.
What is difference between dengue fever and Hemorrhagic Fever?
Despite the name, the critical feature that distinguishes DHF from dengue fever is not hemorrhaging, but rather plasma leakage resulting from increased vascular permeability. EVALUATE the patient’s heart rate, capillary refill, skin color and temperature, peripheral pulse volume, pulse pressure, and blood pressure.
What is the effect of DHF?
Mild dengue fever causes a high fever and flu-like symptoms. The severe form of dengue fever, also called dengue hemorrhagic fever, can cause serious bleeding, a sudden drop in blood pressure (shock) and death.
Which of the following is a complication of DHF *?
The most common complication in DHF/DSS management is fluid overload, which may lead to heart failure, acute pulmonary edema or even death if not managed properly and timely.
How is dengue hemorrhagic fever diagnosed?
If an infection is suspected, you will get a blood test to check for the dengue virus. During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
How do you prevent DHF?
Use insect repellent, wear long-sleeved shirts and long pants, and control mosquitoes inside and outside your home. Each year, an estimated 400 million people are infected with dengue virus through the bites of infected mosquitoes.
Which of the following is a complication of DHF?
Which of the following medication is contraindicated for a patient with DHF?
Avoid aspirins. Aspirin can thin the blood. Warn patients to avoid aspirins and other NSAIDs as they increase the risk for hemorrhage.
Can dengue hemorrhagic fever be cured?
No specific treatment for dengue fever exists. While recovering from dengue fever, drink plenty of fluids. Call your doctor right away if you have any of the following signs and symptoms of dehydration: Decreased urination.
What is the pathogenesis of dengue hemorrhagic fever (DHF)?
Dengue hemorrhagic fever (DHF) is caused by the same viruses and is characterized by increased vascular permeability, hypovolaemia and abnormal blood clotting mechanisms. DHF is a potentially deadly complication with symptoms similar to those of dengue fever, but after several days the patient becomes irritable, restless, and sweaty.
What is severe dengue?
Severe Dengue: Dengue Hemorrhagic Fever and Dengue Shock Syndrome DHF is a vascular leak syndrome and is primarily a disease of children under the age of 15 years, although it can and does occur in adults. 37 It is characterized by sudden onset of fever, usually of 2–7 days’ duration, and a variety of nonspecific signs and symptoms.
What are the signs and symptoms of dengue reinfection?
A similar syndrome is seen in mice with persistent infections with LCMV. Dengue hemorrhagic fever (Chapter 389) and dengue shock syndrome are forms of dengue reinfection characterized by capillary leakage and hemorrhage.
What are the signs and symptoms of DHF?
The illness often begins with a sudden rise in temperature accompanied by facial flush and other flu-like symptoms. The fever usually continues for two to seven days and can be as high as 41°C, possibly with convulsions and other complications. In moderate DHF cases, all signs and symptoms abate after the fever subsides.
