Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Two pig farms with suspected FMD cases were noted in I-Lan county by the local disease control center. Movement restrictions were conducted on these 2 pig farms, serum and swab samples were collected and sent to the national laboratory (Animal Health Research Institute). The laboratory results confirmed positive NSP antibody reaction in serum samples from 2 index farms. The pigs with lesions and others in the same pen in the farm of outbreak 2 were destroyed (total 381 heads of pigs) according to the positive reaction of viral RNA product detected by RT-PCR. Virus isolation are underway. FMD vaccination, the cleaning and disinfection of the index farms were completed. The monitoring and epidemiological investigation of those surrounding farms that keep cloven-hoofed animals within 3-km radius of the index farms had been completed. No clinical or epidemiological evidence of infection were found.
