Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments During the routine active surveillance in the livestock markets, a pig was found NSP antibody positive. The prefecture animal disease control competent authority traced back to the farm of origin. The clinical investigation showed that 112 pigs on the farm had healed vesicular lesions. The prefecture animal disease control competent authority immediately destroyed the 163 pigs (included the pigs other than the 112 pigs in the same pen). Cleaning and disinfection were implemented in the index farm.
Samples for serological tests and virus isolation were collected and sent to the National Laboratory (Animal Health Research Institute). The laboratory confirmed 6 positive results for NSP and all negative for RT-PCR. Further tests are ongoing.
A total of 16 farms within 1-km radius of the index farm have been under vigilant monitoring and no clinical or epidemiological evidence of infection has been found.
