Can't be moved into the beds: they may be disease carriers (8)
I believe the answer is:
contacts
'they may be disease carriers' is the definition.
The definition suggests an adverb but the answer is not.
'can't be moved into the beds' is the wordplay.
'be moved' indicates an anagram.
'into' is an insertion indicator.
'the beds' becomes 'cots' (cot is a kind of bed).
'cant' with letters rearranged gives 'ntac'.
'ntac' going within 'cots' is 'CONTACTS'.
Can you help me to learn more?
(Another definition for contacts that I've seen is " Communicates".)
