Maps and missing malaria--if in doubt request a blood film

Area of Science:

• Tropical medicine
• Infectious diseases
• Parasitology

Background:

• The clinical presentation of malaria can be non-specific, posing diagnostic challenges.
• Changing malaria epidemiology necessitates heightened clinical awareness.
• Severe sequelae from conventionally 'benign' malaria forms are increasingly recognized.

Observation:

• A young man presented with fever and diarrhea, symptoms mimicking other illnesses.
• The patient had no history of travel to recognized malaria-endemic regions.
• Diagnosis of Plasmodium vivax malaria was confirmed.

Findings:

• Plasmodium vivax malaria can present atypically with gastrointestinal symptoms like diarrhea.
• Malaria should be considered in differential diagnoses even in patients without a typical travel history.
• Delayed diagnosis of malaria, regardless of species, leads to poorer clinical outcomes.

Implications:

• Clinicians require heightened awareness of malaria's diverse presentations.
• Diagnostic vigilance is essential for patients presenting with non-specific symptoms.
• Prompt diagnosis and treatment of Plasmodium vivax malaria are vital to prevent severe complications.
