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

'devastating outbreak' is the definition.
I know nothing about this answer so I can't tell whether this works.

'strange pains and bizarre flush' is the wordplay.
'strange' indicates an anagram.
'and' is a charade indicator (letters next to each other).
'bizarre' is an anagram indicator.
'pains' anagrammed gives 'spani'.
'flush' is an anagram of 'shflu'.
'spani'+'shflu'='SPANISH FLU'

'involving' acts as a link.

Can you help me to learn more?

(Another definition for spanish flu that I've seen is " Cause of 1918 pandemic".)
