Pale Face, Bruises, and Fever in a 4-Year-Old: Could It Be Dengue?

The triad of pallor, bruising (petechiae/ecchymoses), and high fever in a young child raises concern for dengue fever—a mosquito-borne flavivirus endemic in tropical/subtropical regions.

Dengue Warning Signs

• High fever (40°C/104°F)
• Severe headache, retro-orbital pain
• Myalgia/arthralgia (“breakbone fever”)
• Petechiae, positive tourniquet test
• Mucosal bleeding (nose, gums)
• Hepatomegaly, ascites
• Lethargy, restlessness

Severe Dengue (DHF/DSS)

Plasma leakage → shock, fluid accumulation, severe bleeding, organ impairment. Mortality <1% with proper fluid management; up to 20% if untreated.

Immediate Actions

• Seek medical care today. Dengue is diagnosed by NS1 antigen (early) or IgM/IgG serology; CBC shows thrombocytopenia, hemoconcentration.
• Do not give NSAIDs/aspirin (increases bleeding risk). Use acetaminophen for fever.
• Hydrate aggressively (oral or IV per clinical assessment).
• Monitor for warning signs: abdominal pain, persistent vomiting, bleeding, lethargy.

Other considerations: leukemia, aplastic anemia, ITP, meningococcemia, HUS. Rapid evaluation is critical.
