Molecular detection of influenza D virus (IDV) infection in swine, Northern Ireland. A) Percentage of nasal swab samples (n = 30) collected from 10- to 12-week-old growing pigs testing positive for IDV RNA by rRT-PCR. B) Plot of Ct values for IDV-positive rRT-PCR nasal swab samples per farm. Horizonal lines indicate mean Ct values. C) Locations and proximity of IDV-positive swine units. Ct, cycle threshold; rRT-PCR, real-time reverse transcription PCR.
