The facility and equipment are designed to isolate the virus from manufacturing associates, therefore reducing the biosafety level concerns.
All residual biological samples collected during the patient's hospital stay were sent to the virology laboratory of the Spallanzani Hospital (Italy's national reference laboratory for viral hemorrhagic fever viruses, BioSafety Level 4) in compliance with biosafety procedures.
