Abstract:

Senecaviral disease is an infectious disease of animals caused by Senecavirus A (SVA), which is classified in the Picornaviridae family. SVA mainly infects pigs, and pigs of different ages are susceptible to SVA infection. However, different SVA isolates have distinct pathogenicity phenotypes for pigs, thus causing diverse clinical symptoms. Although early SVA isolates typically led to subclinical infection in pigs, those obtained in recent years usually cause clinical symptoms similar to foot-and-mouth disease. Vesicular lesions and ulcers were usually visible on the snout and/or coronary bands of SVA-infected pigs, and the neonatal mortality rate was signi-ficantly increased. At present, the disease is mainly endemic in Canada, Brazil, the United States and several other countries. However, there have been reports describing the outbreak of SVA infection in pigs in Guangdong and Hubei Province, China since 2015. In order to raise awareness and draw attention to the disease, to formulate relevant prevention and control plans, and to reserve diagnostic techniques for this disease as early as possible, the latest research progress in the aspects of etiology, epidemiology, clinical symptoms and pathologic changes, quarantine and diagnosis, prevention and control of the disease will be summarized in this review.
