Learn about dengue

Dengue fever is a serious disease that many people know this, but the information about this disease that parents do not know or have not properly understood. Parents need to refer this matter carefully to prevent both the child and the risk of disease.

Dengue hemorrhagic fever is an acute infectious disease caused by the dengue virus, spread by blood-sucking midges Aedesaegypti containing the viral disease and to heal the burn and transmit the virus.

Main clinical features of dengue hemorrhagic fever, enlarged liver, shock can lead to death if not treated appropriately and promptly. In Vietnam, the disease occurs throughout the year, culminating in the rainy season, diseases common in populated areas, poor sanitation, less common in high mountains.

Dengue can occur in both children and adults. Disease called primary infection first, second disease called reinfection. Dengue virus antibody light only with the protective tube of serum have, so patients can be infected with another type when re-infection serum (available antibodies in the blood) or in children also feeding (maternal antibodies transferred to). There are two possible cases: if neutralizing antibodies may inactivate the virus, but if there are antibodies euphoria intense reaction occurs creating a chain reaction leading to plasma leakage phenomenon the cell space. Exit status of blood plasma condensed, reduced blood flow, plasma extravasation if greater than 20%, the patient will fall into cardiovascular collapse, shock. Hemorrhage in Dengue hemorrhagic fever may be due to causes: coagulopathy, decreased platelet count and the circuit is unstable, fragile.

The level of disease:

The severity of disease was evaluated according to the following distribution:

Grade I: fever and positive seal belt

Grade II: the first symptom of natural and bleeding in some areas such as the skin, the lining of the digestive tract ... Circuit, blood pressure remained within normal limits.

Grade III: In addition to the symptoms of grade I, grade II status also expressed shock with tachycardia, mild, low blood pressure or clamp, more cold, tingling or numbness.

Grade IV: severe heart failure status with no pulse and blood pressure were measured.

The classification ignores a number of factors such as respiratory failure, failure of organs such as the liver, heart, nervous ...

Currently, there is proposed a new classification of disease severity as follows:

Standard admission

Signs drainage: dehydration, intolerance services, sweat, cold limbs.

Signs of dengue hemorrhagic nature does not depend on the number of platelets.

Multi-organ failure: Listed jaundice, chest pain, shortness of breath.

So far, studies have not demonstrated the use of corticosteroids to prevent progression to shock.

Highly fatal hemorrhage in adults: platelet transfusion can prevent or reduce bleeding complications.

Prevention

Sanitation, clean up stagnant water where there is no place for mosquitoes to lay their eggs, lentils quang.Tranh kill mosquitoes, mosquito spraying, bed nets, especially children sleep during the day.
