'infection deaths reported among drivers' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'material complaint following' is the wordplay.
I cannot quite see how this works, but
'complaint' could be 'flu' (flu is a kind of health problem) and 'flu' is found in the answer.
'following' could be 'f' (used when citing page numbers etc) and 'f' is found within the answer.
This explanation may well be incorrect...
