What symptom pattern is commonly associated with malaria?

• A. Persistent cough and chest pain.
• B. Rash with joint pain.
• C. Fever with chills, sweating, and flu-like symptoms; may have cyclical fever.
• D. Diarrhea with vomiting not associated with fever.

Answer: (C)

Malaria typically shows fever with chills, sweating, and flu-like symptoms, and often follows cyclical fever patterns as part of the parasite’s blood-stage cycle. The cold stage (shivering), hot stage (fever), and sweating recur in paroxysms every 48 hours or 72 hours depending on the species, reflecting synchronized rupture of infected red blood cells. This pattern, along with possible headaches and malaise, is distinctive. In contrast, persistent cough and chest pain point to a respiratory illness, rash with joint pain suggests a ricketial or other inflammatory condition, and diarrhea with vomiting without fever aligns more with gastroenteritis.
