What are the Symptoms of Dengue Fever?

Common symptoms of dengue fever include fever, rash, or bleeding. These are the initial symptoms of the disease, which onsets very acutely. The first symptom is usually a sudden high fever accompanied by chills. After 3 to 5 days of fever, the body temperature will gradually decrease. When these symptoms occur, it is important to seek medical attention promptly.

Fever is a typical and initial symptom of dengue fever. As the body temperature rises, patients may experience chills and shivering. Occasionally, some patients may also experience fatigue, nausea, and other gastrointestinal discomfort symptoms. These are mostly early symptoms. As the condition worsens, it may lead to shock and other serious problems.

As the condition worsens, patients may also experience severe abdominal pain, persistent vomiting, shock, or multiple organ dysfunction, and disseminated intravascular coagulation. These symptoms pose a significant threat to life, and it is important to take prompt measures for treatment.

The cause of dengue fever is also important to understand. It is usually caused by the binding of dengue virus with antibodies, forming immune complexes that activate the immune system, leading to increased vascular permeability, vasodilatation, and other pathophysiological changes such as blood concentration. It is also important to take preventive measures from the source.
