Sickly, even if ABC gets right quarantine outcome? (5,5)

I believe the answer is:

cabin fever

I'm a little stuck... Click here to teach me more about this clue!

'quarantine outcome?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'sickly even if abc gets right' is the wordplay.
'sickly' indicates anagramming the letters (I've seen this in other clues).
'gets' means one lot of letters go next to another.
'right' becomes 'r' (common abbreviation).
'even'+'if'+'abc'='evenifabc'
'evenifabc' is an anagram of 'cabinfeve'.
'cabinfeve'+'r'='CABIN FEVER'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
