The Outcome of PCR Versus IGM Timing Study in the Diagnosis of theCrimean-Congo Hemorrhagic Fever Outbreak in Iraq during 2021-2022
Key Points
PCR testing is the gold standard for CCHF diagnosis during the first 15 days of illness, maximizing detection rates.
Anti-CCHF IgM testing becomes reliable starting from day 5, contributing to diagnosis later in the illness timeline.
Understanding the timing between PCR and IgM can enhance diagnostic accuracy for CCHF outbreaks and improve patient outcomes.
Identifying optimal testing strategies is crucial for timely interventions, especially during an outbreak situation.
Abstract
The gold standard for CCHF diagnosis is PCR testing within the first 15 days of illness, while anti-CCHF IgM testing becomes useful from day 5 onwards.
