Guide To The Causes, Risk Factors, And Transmission Of Ringworm

Ringworm, dermatophyte infection, and dermatophytosis are terms used to describe a skin infection caused by one of several types of fungi. Despite the name of the infection, no parasites cause an individual to develop ringworm. Symptoms of ringworm are dependent upon the location of the body it is affecting. When ringworm affects the skin, an individual may develop plaques on the skin that are scaly, red, and itchy. These plaques may form into pustules or blisters, and they may have a darker red color on their border that resembles a ring. When ringworm affects a patient's nails, they can experience discoloration, abnormal thickening, or may crack. When ringworm affects the scalp, bald patches may form. Diagnosis of ringworm is made with a physical examination with a blacklight, skin biopsy, fungal culture, and KOH or potassium hydroxide examination.

There are several causes and risk factors for the transmission and infection of ringworm. Learn about them now.

Human To Human

In the United States, the most common source of ringworm infection is contact with other infected humans directly and by contact with objects belonging to another infected person. Direct skin contact allows for the fungus to be transmitted to a new host without being killed off by external factors that would play some role if the fungus was transferred to an object before another host. A common source of ringworm transmission between humans is through participation in direct contact sports, including rugby, soccer, football, wrestling, lacrosse, and basketball. These sports can cause the transmission of ringworm because they involve a large amount of direct skin contact between two or more individuals. When children who are between four and eleven years old develop ringworm infection, it most often occurs on the scalp and face. Individuals who have compromised immune systems are at a greater risk of developing a ringworm infection when they participate in any activity that involves contact with the skin of others.
