It will depend on the size of the tissue and the source.
Lung tissue is the major concern. Other tissues not affected as much (based on the burgeoning literature on Covid-19).
Routine fixation time are applicable, remembering that the alcohols and heated wax will also inactivate the virus (triple whammy).
I suppose that I better add a reference:

How long are you fixing surgical tissue specimens from COVID-19 positive patient's before tissue processing? I know that the CDC is recommending "72" hours for autopsy tissues, but, to me, that seems excessive for surgical pathology specimens. Any information that you can share on this subject would be appreciated. Thank you and stay safe.
