Key result
The newly emerged subgenotype 2.1d isolate of CSFV (HLJZZ2014 strain) is moderately virulent, causing lower mortality and viral load compared to the highly virulent Shimen strain.
The recently emerging subgenotype 2.1d isolate of CSFV in China is a moderately virulent strain with molecular variations and antigenic alterations that may evade current vaccines.

Alerts to evolving CSFV dynamics in swine; leaves open needs for updated surveillance and control strategies.
Luo et al. (2016) studied Classical swine fever. HLJZZ2014 strain (subgenotype 2.1d) vs. Shimen strain was evaluated on Mortality, clinical signs, pathological changes, virus shedding, and viral load. The newly emerged subgenotype 2.1d isolate of CSFV (HLJZZ2014 strain) is moderately virulent, causing lower mortality and viral load compared to the highly virulent Shimen strain.
