Due to a production error, there was a mistake in Table 2 and Table 3 as published. Table 2 and Table 3 were published in the wrong order. The corrected order of Table 2 and Table 3 appears below.

| Suckling and nursing piglets | Piglet diarrhea | 91 | 12 | 13.19% | |
| Nursing piglets | Piglets died of encephalitis | 51 | 1 | 1.96% | |
| Nursing piglets | Dead stiff pig | 60 | 1 | 1.67% | |
| Nursing and fattening pigs | Dead pigs with red and cyanotic skin | 165 | 97 | 58.79% | |
| Fattening pigs | Residual pig death | 54 | 9 | 16.67% | |
| Nursing piglets and sow | Emaciation and loss of appetite | 86 | 19 | 22.09% | |
| Pregnant sows | Reproductive disorder | 166 | 48 | 28.92% |
Distribution of different viremias.

Distribution of PCV2 in different organs.
A total of 794 clinically suspected samples were necropsied, and the overall positive rate of PCV2 was 19.43%. PCV2 was detected in all tissue and organ types submitted for inspection.
The publisher apologizes for this mistake. The original article has been updated.
