SCDNR: Rabbit disease concerns South Carolina wildlife officials | 99 7 | 1230 WSOK

|April 20, 2021 at 10:31 AM EDT - Updated April 20 at 10:31 AM COLUMBIA, S.C. (WTOC) - South Carolina Department of Natural Resources officials are concerned about a rabbit disease they say affects wild and domestic rabbits and is nearly always fatal. According to SCDNR, Rabbit Hemorrhagic Disease Virus-2 (RHDV2) is a highly contagious disease that affects all rabbits. Fortunately, humans are not susceptible to RHDV2, but they can inadvertently spread the virus. “This is a highly contagious disease that can persist in the environment for a very long time,” said Michael Hook in a statement, Small Game Project leader with the S.C. Department of Natural Resources (SCDNR). “These factors make disease control efforts extremely challenging once it is in wild rabbit populations.”

Avian influenza A(H7N3) virus on commercial turkey farms in NC & SC, USA | Infectious Diseases 2020 | Infectious diseases

Avian influenza A(H7N3) virus on commercial turkey farms in NC & SC, USA Emerging Infectious Diseases. 2020;26(12):2966-2969. 13 December, 2020 Highly pathogenic avian influenza viruses (HPAIVs) have devastating impacts on the poultry industries. With infections in poultry, H5 and H7 low-pathogenicity avian influenza viruses (LPAIVs) have spontaneously mutated into HPAIVs by different mechanisms, one of which is acquisition of basic amino acids at the hemagglutinin (HA) cleavage site. In March 2020, an outbreak of LPAIV H7N3 occurred in turkey farms, affecting 11 premises in North Carolina and 1 in South Carolina, USA. The initial decision to depopulate LPAIV-affected flocks was based on a risk assessment that included the location of affected premises, the poultry density in the area, and the presence of a basic amino acid substitution at the cleavage site among the initial LPAIV detections (PEKPKTR/GLF; substitution sequence is highlighted).
