Find hole in broken car is caused by disease (7)
I believe the answer is:
cholera
'disease' is the definition.
(cholera is a kind of disease)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for cholera that I've seen before include "Disease contracted from infected water" , "Acute intestinal infection from contaminated water or food" , "bacterial disease" , "serious illness" , "Intestinal infection caused by contaminated water or food" .)
