2. **Identify the Conditions Favoring Growth**: Fungi thrive in warm and moist environments. Therefore, these conditions should be controlled to prevent the growth of fungi.

3. **Recognize Transmission Methods**: Ringworm can be transmitted through direct contact with infected individuals or contaminated objects such as towels, clothes, and combs.

4. **Emphasize Personal Hygiene**: Improving personal hygiene is crucial. This includes regularly washing hands, avoiding sharing personal items, and keeping the skin dry and clean.

5. **Maintain Environmental Hygiene**: Along with personal hygiene, maintaining cleanliness in the surroundings is essential to prevent the spread of the fungus.

7. **Conclusion**: The most effective way to prevent ringworm is by improving personal hygiene and maintaining cleanliness in the environment.

**Final Answer**: Ringworm can be prevented by improving personal hygiene and maintaining cleanliness in the surroundings.
