Jock itch or groin ringworm is caused by a variety of yeast and fungi. This infection is more predominant in men than women and tends to develope during the warmer months of the year. The symptoms of jock itch may include red, ring like areas, occasionally with small blisters on the skin around the groin and in the area around the upper, inner thighs. The area will often be very itchy and sometimes even painful. Since the fungi can survive indefinitely on the skin reoccurrences are common and even when the proper treatment is given the infection may repeat itself if the person is susceptible.
Scalp ringworm is highly contagious and especially among children.
It is caused by either the fungi trichophyton or microsporum and may produce a scaly red rash that can feel itchy. In some cases it will produce a patchy area of hair loss without producing a rash. Nail ringworm occurs when the fungi trichophyton gets into the newly forming part of a finger or toenail. Once there it produces a lusterless thickening that deforms the nail. This type of ringworm is found more often on the toenail than the fingernail.
