Where infectious type might go with rival boss (5)
I believe the answer is:
viral
'where infectious' is the definition.
'viral' can be an answer for 'infectious' (I've seen this in another clue). I'm not sure about the 'where' bit.
'type might go with rival boss' is the wordplay.
'rival' anagrams to 'VIRAL'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for viral that I've seen before include "Of organisms that transmit infectious disease" , "Caused by pathogenic agent" , "Like pathological agents" , "Pertaining to an ultramicroscopic infection" , "Go ___ (take off via the internet)" .)
