Ringworm is a fungal infection--there is no worm involved, despite the name. The infection often presents in a ring shape, though not always. When the fungal infection involves the feet it is referred to as "athlete's foot" and when it involves a male's genital area it is often called "jock itch." Ringworm can occur anywhere on the skin and sometimes is found on the scalp or the nails. It has specific symptoms, which can make diagnosis relatively easy.
Step 1
Observe the appearance of the area. If it is a scaly, red rash appearing in a ring shape you probably have ringworm. It should be noted, however, that ringworm infections do not have to have this characteristic shape.
Step 2
Note whether there are raised bumps. Ringworm infections generally have small, raised red bumps gathered in a small (rather than diffused) area. The bumps will usually be very itchy and dry (though occasionally they may be wet and ooze).
Step 3
Use two mirrors to get a look at an itchy area on the scalp. Stand with your back to a full-size mirror while holding a hand mirror over your head until you can see the problem area. See if the area is bumpy and red. You may have to move hair aside or you may have lost hair in the area.
Step 4
Look carefully at the borders of the rash. If it is scaly this is another indication that it may be a fungal infection. Use a magnifying glass to get a definitive view. While the outer edges will be scaly, the center will likely look clear.
Step 5
Consider the company you have been keeping. Have you been around any children or animals that may have been infected? Ringworm is spread from human to human and human to animal. You can also contract ringworm from objects an infected individual has used and, very rarely, from soil.
Step 6
Get a definitive diagnosis by having your physician examine the rash. He may need to take a scraping of the affected area and view the cells under a microscope to be absolutely sure it is ringworm.
Tips and Warnings
- Help prevent fungal infections by wearing sandals in gyms and around pools.
- Never share combs, razors, towels, clothing or other personal items, as these can spread infections. Avoid animals with bald spots in their fur.
