International Research Consortium on Dengue Risk Assessment, Management, and Surveillance

Improvements in diagnosis of dengue fever and prediction of which patients will get more severe disease are urgently needed to improve the treatment of patients with dengue. This is very important in places with many people who suffer from dengue but have limited health care resources. This study will enroll patients with fever which may be caused by dengue in 6 countries with high incidence of dengue over two continents (Brazil, Cambodia, El Salvador, Indonesia, Malaysia and Vietnam). All patients will be followed by a doctor with blood tests and exams until they recover. Symptoms and laboratory tests will be followed so that the cause of fever can be determined. For patients who have dengue, the investigators will look for symptoms and tests which indicate more serious disease. This study will help to determine how to identify patients with dengue fever based on symptoms and simple laboratory tests and those who will get more serious disease. It will also help to define a more standardized management of patients with dengue fever.
