Which clinical pattern would raise suspicion for a viral hemorrhagic fever in a potentially exposed patient?

• A. Isolated sore throat with no fever
• B. Acute febrile illness with bleeding manifestations and exposure history
• C. Chronic cough
• D. Mild abdominal pain

Answer: (B)

Viral hemorrhagic fevers are suspected when a patient has an acute fever accompanied by bleeding symptoms and a plausible exposure history. The combination of sudden fever, signs of bleeding (such as bruising, bleeding gums, nosebleeds, or blood in vomit or stool), and a history that includes potential contact with the virus (like travel to areas where VHFs are present, contact with infected people or animals, or exposure to bodily fluids) is the red flag that sets off concern for a hemorrhagic fever.

In this scenario, the pattern described—an acute febrile illness with bleeding manifestations and an exposure history—best fits that red-flag profile. The other patterns don’t align as well: an isolated sore throat without fever is more typical of a simple viral or bacterial throat infection; a chronic cough suggests a longer-standing respiratory process rather than an acute hemorrhagic syndrome; mild abdominal pain alone is nonspecific and lacks the fever and bleeding signals that would point toward a VHF. Immediate recognition of the high-risk combination is crucial for infection control and appropriate public health actions.
