Crossword Genius

Disease from Eastbourne, say (7,6)

Ross

I believe the answer is:

seaside resort

'eastbourne say' is the definition.
(Eastbourne is a seaside resort)

'disease' is the wordplay.
I cannot quite see how this works, but
an anagram of 'disease' is 'seaside' which is located in the answer.
The remaining letters 'resort' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'from' acts as a link.

(Another definition for seaside resort that I've seen is " Coastal place much visited".)

I've seen this clue in The Guardian.
