What is a characteristic of suspected dengue?

A characteristic of suspected dengue is the presence of acute febrile illness lasting from 1 to 7 days, accompanied by at least two specified symptoms such as severe headache, retro-orbital pain, myalgia, arthralgia, rash, or hemorrhagic manifestations. This definition aligns with the clinical criteria often utilized in dengue surveillance and management, allowing healthcare providers to identify cases that may require further investigation or confirmation.

Option A refers to a confirmed case, which requires laboratory validation of dengue virus infection. In contrast, suspected dengue does not necessitate laboratory confirmation at the initial assessment stage. Option C describes severe dengue, which involves acute febrile illness but with significant complications that indicate a more advanced stage of the disease. Lastly, option D suggests diagnosing dengue without symptom criteria, which does not align with clinical practices that rely on symptom assessment to guide initial suspicion of the disease.
