When you have ringworm you will notice a round red patch on the skin. The ringworm is not actually a worm inside of you or caused by a worm.
The ringworm is just a fungal infection of the skin caused by bacteria.
If you have ringworm or you're starting to get ringworm you should see a doctor about it so they can prescribe you some antibiotics or even fungal cream to cure the ringworm.
