Visitors to Nebraska prisons will have to answer questions about their possible exposure to the new coronavirus as part of an effort to keep staff and inmates from getting infected. The Department of Correctional Services says visitors will still be allowed, as long as they are deemed a low risk. But Director Scott Frakes warned that the policy could change quickly. Visitors, volunteers, contractors and others will be asked to confirm that they are symptom-free, verify if they have had contact with anyone diagnosed with COVID-19 and if they have traveled recently by plane. Visitors who answer “yes” to any of those questions will be denied entry.
