Dengue is most often a benign disease that is cured without sequelae. However, it can be serious in children under 15 years of age where hemorrhages can be life threatening.
Dengue is manifested by symptoms such as high fever, headaches behind the eyes, nausea, vomiting, muscle and joint pain. There is sometimes a rash that resembles that of measles. A few days after the disappearance of clinical symptoms, may appear nosebleeds, conjunctival haemorrhages, bruises. The cure is spontaneous and total in a fortnight.
In some cases, dengue fever may worsen 3 to 7 days after the first symptoms. This is called severe dengue, or dengue haemorrhagic fever. The symptoms are more severe, with a persistent fever associated with major and multiple haemorrhages: cerebral, digestive, cutaneous.
Haemorrhages can cause dramatic blood loss. And so cause death if an intravenous infusion to restore blood volume is not quickly put in place.
Severe forms of dengue fever are more common in children under 15 years of age. A blood test will confirm the diagnosis and early management of severe forms can prevent a fatal outcome.
