Answer

To determine which disease is not caused by bacteria, we will analyze each option provided:

1. **Cholera**: This disease is caused by the bacterium *Vibrio cholerae*. It is primarily transmitted through contaminated water. Therefore, cholera is caused by bacteria.

2. **Typhoid**: This disease is caused by the bacterium *Salmonella typhi*. It leads to fever and is also transmitted through contaminated food and water. Thus, typhoid is caused by bacteria.

3. **Tuberculosis**: This disease is caused by the bacterium *Mycobacterium tuberculosis*. It primarily affects the lungs and is spread through the air. Hence, tuberculosis is caused by bacteria.

4. **Measles**: This disease is caused by a virus known as the *Morbilivirus*. It is not caused by bacteria but rather by a viral infection.

Based on the analysis above, the disease that is not caused by bacteria is **measles**.
