With virus going round, medic gets a little pouch (6)
I believe the answer is:
bumbag
'little pouch' is the definition.
(bag worn around one's waist)
I can't explain the rest of the clue.
(Other definitions for bumbag that I've seen before include "Small back pouch on a belt" , "carrier" , "skiers' accessory" , "Pouch worn round the waist or hips" , "Waist pack worn with the pouch at the back" .)
