Earlier this year, the Institute of Museum and Library Services (IMLS) held a webinar on this very topic with David Berendes, a CDC epidemiologist.

“You don’t have to really worry about finding ways to disinfect those materials,” Berendes said to the attendees, according to a recap of the meeting. “The virus, if it’s present, would be present in very low quantities and would die off pretty quickly.”
