Characterization of prolonged shedders and pigs reinfected with swIAV. A The graph shows the distribution of HI titres at the moment when the first swIAV infection was detected in single shedders, prolonged shedders, and reinfected pigs. B Variation in Ct values between the first and consecutive detections of swIAV in nasal swabs from prolonged shedders. Upper: Ct values for cases in which the second detection resulted in a decrease in the viral load higher than 3.3 Ct units; middle: Ct values for animals that showed similar viral loads in consecutive samplings; and lower: Ct values for cases where viral loads increased between consecutive samples. C Distribution of HI titres when swIAV was detected for the first time in the animals shown in B.
