The importance of aerosol exposure is not known. Biosafety Level 2 practices, containment equipment and facilities are recommended for all activities involving the use or manipulation of known or potentially infectious tissues, body fluids, and cultures, and for the housing of infected animals. Gloves are recommended for the handling and necropsy of infected animals, and when there is the likelihood of direct skin contact with infectious materials. Vaccines are not available for use in humans. Challenged rabbits develop antibodies but not clinical disease.
Mice are refractory to parenteral exposure.
Biosafety Level 2 practices, containment equipment and facilities are recommended for all activities involving the use or manipulation of known or potentially infectious clinical materials or cultures, and for the housing of infected animals. Vaccines are not available for use in humans. There are no cases reported as a result of working in a laboratory with biopsy or other clinical materials of human or animal origin. The infectious agent may be present in tissues and exudates from lesions of infected humans and experimentally or naturally infected animals. Direct contact of the skin and mucous membranes with infectious materials, and accidental parenteral inoculation, are the primary laboratory hazards associated with handling infectious clinical materials.
