Disease causing wild alarm at the podiatry centre (7)
I believe the answer is:
malaria
'disease' is the definition.
(malaria is a kind of disease)
'wild alarm at the podiatry centre' is the wordplay.
'wild' indicates anagramming the letters.
'at' says to put letters next to each other.
'centre' indicates the central letters.
The central letters of 'podiatry' are 'ia'.
'alarm' with letters rearranged gives 'malar'.
'malar'+'ia'='MALARIA'
'causing' acts as a link.
(Other definitions for malaria that I've seen before include "Tropical fever" , "Disease carried by mosquitoes" , "Fever disease transmitted by mosquitoes" , "Am a liar (anag) - fever" , "Mosquito-borne fever" .)
