Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a disease that is transmitted by houseflies. We need to identify such a disease.

2. **Identifying the Role of Houseflies**: Houseflies are known to be carriers of germs and microorganisms. They do not bite like mosquitoes but can contaminate food and water.

3. **Eliminating Other Diseases**:
- Malaria is caused by the bite of the female Anopheles mosquito, so it is not transmitted by houseflies.
- Other diseases like typhoid and dysentery can also be considered, but we need to focus on the most common one associated with houseflies.

4. **Identifying Cholera**: Cholera is a disease that is primarily caused by consuming contaminated food or water. Since houseflies often land on food and can carry germs from unsanitary areas, they can transmit the bacteria that cause cholera.

5. **Conclusion**: Therefore, the disease that is transmitted by houseflies is cholera.

**Final Answer**: Cholera is a disease transmitted by houseflies.
