The fungus that causes ringworm is a fungus known as dermatophytes. The thing that makes dermatophytes attack the human body is a protein that can be found in our nails, hair, and skin surfaces known as keratin. This is why dermatophytes only attacks our skin, hair, scalp, and nails. These are the areas of the body that has the most keratin to attract the fungus.
Dermatophytes can easily survive in items such as brushes, towels, and other objects which is why ringworm can easily spreads from one item to a person. The dermatophytes are microscopic spores that will live on the skin surface for months and can easily spread from animal to human, human to human, surface to human and object to human.
Some adults have a strong enough immune system that will prevent the dermatophytes fungus from showing up or any symptoms but they can still pass on the spores to other people like kids who are much more likely to display symptoms once affected since their immune system isnâ€™t very strong yet. You will be more at risk of developing the ringworm causing fungus due to one or more of the following:
You are very old
You are very young
You have a medical condition that makes you more vulnerable such as diabetes or hyperhidrosis
You are obese
You have a weak immune system
You are taking certain medications that lower your immune system
