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 anagramming the letters.
'into' indicates putting letters inside.
'the beds' becomes 'cots' (cot is a kind of bed).
'cant' anagrammed gives 'ntac'.
'ntac' put within 'cots' is 'CONTACTS'.
Can you help me to learn more?
(Another definition for contacts that I've seen is " Communicates".)
