Dengue.

Area of Science:

• * Infectious Diseases
• * Virology
• * Immunology

Background:

• * Dengue virus outbreaks continue to pose a global health threat.
• * Current dengue control efforts are facing challenges.
• * Understanding severe dengue mechanisms is crucial for effective treatment.

Purpose of the Study:

• * To review the mechanisms underlying severe dengue disease.
• * To evaluate current and potential treatment options for dengue.
• * To highlight the importance of early diagnosis and appropriate patient management.

Main Methods:

• * Comprehensive literature review of dengue pathogenesis and clinical management.
• * Analysis of diagnostic tests, including the tourniquet test.
• * Evaluation of treatment strategies for dengue hemorrhagic fever and dengue shock syndrome.

Main Results:

• * The tourniquet test is not definitive for ruling out dengue; a positive test warrants close monitoring.
• * Platelet counts alone are insufficient indicators for transfusions in dengue patients.
• * Severe dengue can often be managed effectively with normal saline, with colloids indicated for specific shock presentations.
• * Genetic factors, such as Human Leukocyte Antigen alleles, influence dengue susceptibility and severity.

Conclusions:

• * The role of antibodies in dengue infection, both protective and enhancing, requires further investigation.
• * Future research should focus on identifying infected cells and early antibody-accessible infection steps in human dengue.
