2. Without treatment cholera can kill, but drinking clean water with salts and sugar (rehydration) and medicine save most people. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/C/cholera/#m2)

### In the lessons

In history and science lessons, cholera is famous because a doctor named John Snow found that people caught it from a dirty water pump in London, which helped create clean water systems and sewers. In geography and current affairs, cholera still spreads where there is war, floods or no clean water. It teaches why washing hands and safe water matter. Phrases: «a cholera outbreak», «cholera epidemic».
