Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments During the routine active FMD serological surveillance, NSP antibodies were detected on one pig farm. Serum and throat swab samples for serological tests and virus isolation were collected and sent to the national laboratory (Animal Health Research Institute). The laboratory confirmed positive results with NSP antibody, whereas the results of virus isolation and RT-PCR were all negative. The serotype O was identified by using FMD ELISA kit. The monitoring and epidemiological investigation of the index farm and those surrounding farms that keep cloven-hoofed animals (a total of 31 pig farms, and 4 goat farms within 3-km radius of the index farm) have been done and no clinical or epidemiological evidence of infection was found.
