Reports from China say a new subgenotype of Classical Swine Fever virus (CSFV) is responsible for recent outbreaks in that country, according to the Swine Health Information Center (SHIC).. The Center reports that further results show specific antibodies elicited by vaccination of C-strain vaccine could not effectively protect against the new strains of CSF found in China, leading to the new cases.

"An article in the Veterinary Microbiology journal (201, 2017, 154-161) highlights an emerging disease issue occurring in China," said the article in the SHIC newsletter. "For decades, CSF has been controlled in China due to extensive, mandatory vaccination with C-strain-based commercial vaccines. Recent frequent CSF outbreaks in this Asian nation have raised concern internationally and the Swine Health Information Center is monitoring developments closely."
