In spite of its popular name, the actual cause of ringworm is infection with fungal organisms. These infectious fungal organisms are called dermatophytes and the medical term for ringworm is dermatophytosis. Sometimes ringworm is also known as tinea. The fungal infectious organisms responsible for causing ringworm are widespread in nature and they commonly populate the soil. The only effective means of preventing the occurrence of ringworm is to maintain a good hygiene. Ringworm is very contagious and it can easily be acquired through direct contact with contaminated people, animals or objects. Regularly wash your hands after entering in contact with stray animals, as many of them are carriers of the fungi responsible for causing ringworms in humans.

Arthrospores are the main cause of ringworm in humans. Although there are lots of animals contaminated with arthrospores, they usually don't show any signs of the disease. For some reason, most animals appear to be immune to this form of fungal infection. Microsporum canis is a type of fungi that commonly infects cats. This type of fungus can be easily transmitted to other animals and to humans. It is strongly recommended to avoid physical contact with animals that show signs of disease in order to prevent contamination with infectious fungal elements. Also, if you own a dog or a cat, ensure that your pet is not contaminated with dermatophytes by paying regular visits to a veterinary.

Ringworm can affect virtually any region of the body. Hands and feet are very exposed to fungal infection and dermatophytes often infect these body parts. Although it commonly affects skin, ringworm can also affect nails and scalp. Ringworm involves inflammation, rash and swelling of the skin, scalp, soft tissue and nails. Rash is usually the first sign that indicates the presence of fungal infections. Skin lesions may also appear in later stages of the disease. If the infection spreads through the deeper layers of the skin it can cause pustules and painful nodules. A hardened crust often forms on the surface of the affected skin. Common symptoms of ringworm are persistent itching, soreness and irritation.

Ringworm of the scalp appears in the form of pustules or pus-filled reddish bumps. Foot ringworm usually affects the skin regions between the toes. Foot ringworm appears in the form of cracked, hardened skin. The affected skin also tends to exfoliate, causing itching and soreness. Ringworm of the nails is manifested by thickening and discoloration of the nails.

It is very important to see a dermatologist if you have the symptoms of ringworm. Although it may resemble a simple rash or irritation, ringworm can cause serious complications if it is not appropriately treated. The treatment for ringworm can be prescribed in the form of oral tablets or creams and ointments for external use. The medications used in the treatment for ringworm contain antifungal material and they are usually very effective in overcoming the infection. With appropriate medical treatment, ringworm can be completely cured within a week.
