Moving out tenant refusing access to potential tenants

[Sam P.]

Tenant gave me 30 day notice yesterday in conformance with the lease agreement. It was out of the blue, since earlier she said she wanted to extend. She does not want potential tenants to tour the place, because she has a very young child and does not want her to be exposed to Covid. She is instructing me to take video and show it to potential tenants. Can she refuse entry, what options do I have? One thought I have is to provide potential tenants with gloves and booties and tell them not to touch anything. Is that ok? 

This is in Illinois, Chicago suburbs
