: A positive result confirms a dengue infection, though it does not specify which of the four serotypes (DENV 1-4) is responsible.
In acute febrile patients with suspected dengue, a positive DNS1 test confirms acute infection, distinguishing it from post-recovery phases or other flavivirus cross-reactivity. Negative DNS1 with positive IgM suggests past or late-stage infection.
Maya, the index patient, recovered. But the sentinel system Elias ran was now tracking hundreds.
Elevated DNS1 levels correlate with high viral load and are associated with an increased risk of developing severe dengue (e.g., plasma leakage, shock, thrombocytopenia). Serial DNS1 measurements can help identify patients who may require closer monitoring.
