Disease class
Dengue is a mosquito-borne disease caused by dengue virus infection.
Core mechanism
It is transmitted mainly through bites of infected Aedes mosquitoes.
Genes or cause
Increased vascular permeability and immune responses contribute to plasma leakage and shock in severe dengue.
Typical features
Fever, severe headache, muscle and joint pain, rash, and nausea can occur.
Variability
Abdominal pain, persistent vomiting, mucosal bleeding, fluid accumulation, and altered mental status are warning signs for severe progression.
Diagnosis
Diagnosis combines clinical assessment with virus, antigen, or antibody tests selected by illness timing.
Management
Serial blood counts and hematocrit help assess plasma leakage and clinical course in patients with warning signs.
Treatment and research
There is no specific antiviral treatment for dengue; care is primarily supportive and tailored to clinical status.
Reading evidence
Fluids are adjusted using repeated vital signs, urine output, and hematocrit to avoid both under- and over-resuscitation.
Key caution
Aspirin and NSAIDs are avoided because of bleeding risk, while acetaminophen is used for fever.

For patients and families

A structured guide for understanding the disease and preparing for clinical conversations.

At a glance

Dengue is a mosquito-borne disease caused by dengue virus infection.

Fever, severe headache, muscle and joint pain, rash, and nausea can occur.

How the disease works

It is transmitted mainly through bites of infected Aedes mosquitoes.

Increased vascular permeability and immune responses contribute to plasma leakage and shock in severe dengue.

Why experiences vary

Abdominal pain, persistent vomiting, mucosal bleeding, fluid accumulation, and altered mental status are warning signs for severe progression.

Diagnosis and management

Diagnosis combines clinical assessment with virus, antigen, or antibody tests selected by illness timing.

Treatment status

Serial blood counts and hematocrit help assess plasma leakage and clinical course in patients with warning signs.

There is no specific antiviral treatment for dengue; care is primarily supportive and tailored to clinical status.

Reading clinical trials

Around the critical phase near defervescence, outpatients need clear warning-sign and return-care instructions.

Topics for a clinical visit

Clinical discussion should cover illness day, warning signs, test timing, hydration status, and criteria for immediate reassessment.
