PEV-9 is prevalent in pig populations in middle and eastern China and can cause pyrexia, flaccid paralysis, and pathological changes in the cerebrum and lung in experimentally infected piglets.
Yang et al. (2013) conducted a cross-sectional in Porcine enterovirus 9 (PEV-9) infection (n=447). Porcine enterovirus 9 (PEV-9) was evaluated on Prevalence of PEV-9 infection. The overall prevalence of porcine enterovirus 9 infection in sampled pigs in middle and eastern China was 8.3% (37/447), with the highest frequency in pigs aged 10-15 weeks.
