How to say "cholera" in Japanese

• コロリ
  nounA dated colloquial name for cholera, reflecting how swiftly it could kill; you are most likely to meet it in historical writing, and it is seldom the word you want today.
• 三日コロリみっかコロリ
  nounAn old colloquial name for cholera, alluding to the roughly three days in which it could prove fatal; it turns up almost only in historical contexts and is essentially never the word you want.

All three denote cholera, the infectious disease: 「コレラ」 is the common everyday word, while 「コロリ」 and 「三日コロリ」 are dated colloquial names you will meet mainly in historical writing, so 「コレラ」 is almost always the right choice.
