Figure 2.
The figure shows the distribution of Ct values in 10 nurseries infected by each detected virus. To simplify the graphs, values for negative animals were shown as Ct = 0. The letter in the X-axis indicates the farm code. Detailed values of prevalence, confidence intervals and average Cts are shown in Supplementary material 1. IAV, influenza A virus; PRCV, porcine respiratory coronavirus; PRRSV, porcine reproductive and respiratory syndrome virus; SOV, swine orthopneumovirus; PCMV, porcine cytomegalovirus; PCV2, porcine circovirus 2; PCV3, porcine circovirus 3.
