Recount North America's speed of virus transmission (7)
I believe the answer is:
narrate
'recount' is the definition.
(synonyms)
'north america's speed of virus transmission' is the wordplay.
I cannot really see how this works, but
'north' could be 'n' (synonyms) and 'n' is located in the answer.
'speed' could be 'rate' (rate is a kind of speed) and 'rate' is present in the answer.
'america' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is present in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for narrate that I've seen before include "Relate - portray" , "Give (film) commentary" , "Relate, recount" , "tell tales" , "Rare ant (anag.)" .)
