Place in quarantine (7)
I believe the answer is:
isolate
'place in quarantine' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for isolate that I've seen before include "Place or set apart" , "Cut off from all contact" , "Place apart from others or alone" , "Eat soil (anag)" , "Put into quarantine" .)
