What is the difference between dengue fever and dengue 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 are the 3 stages of dengue fever?
Dengue begins abruptly after a typical incubation period of 5–7 days, and the course follows 3 phases: febrile, critical, and convalescent.
What are the 4 types of dengue fever?

Dengue hemorrhagic fever (DHF): A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock).
Why does dengue hemorrhagic fever happen?
Dengue hemorrhagic fever can occur when someone is bitten by an infected mosquito or exposed to infected blood. Mosquitoes are the most common cause. There are four different types of the dengue virus. Once you contract one of the viruses, you develop immunity to that virus for the rest of your life.

There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor.
What is plasma leakage?
Plasma leakage is a process in which the protein rich, fluid component of the blood leaks from blood vessels into the surrounding tissue. Plasma leakage is the most serious complication that distinguishes dengue from severe dengue.
What is IgG positive in dengue test?
Positive IgM and IgG tests for dengue antibodies detected in an initial blood sample mean that it is likely that the person became infected with dengue virus within recent weeks.
Is dengue hemorrhagic fever curable?
Dengue is a virus, so there is no specific treatment or cure. However, intervention can help, depending on how severe the disease is. For milder forms, treatment includes: Preventing dehydration: A high fever and vomiting can dehydrate the body.
How is dengue hemorrhagic fever diagnosed?
Doctors can diagnose dengue infection with a blood test to check for the virus or antibodies to it. If you become sick after traveling to a tropical area, let your doctor know. This will allow your doctor to evaluate the possibility that your symptoms were caused by a dengue infection.
