Are there any ways to prevent a lawn fungus?

Always avoid overwatering and only water the grass when necessary. 1 inch of water every week should be enough for most lawns. Also try not to dry out your lawn as this can also make it prone to infections. 

Try to keep the grass at a desirable height and do not cut it too low. Try mowing one-third of the grass blades at a time. 

Remember to aerate the soil once every year to prevent the chances of soil becoming compacted. 

Another important tip is to water your lawn in the mornings, ideally from 6am to 10am. This ensures that the water is properly absorbed and that the sun comes out and dries it on time.

Finally, choose the right grass type according to your soil, climate and light conditions. The ideal grass type will be stronger and better at fighting off diseases.
