Causes of Jock Itch

Jock itch is due to Trichophyton rubrum. It is a type of fungus which results to athlete’s foot and ringworm infection of the scalp. Under the microscope, the fungus is similar to a translucent, rod-shaped filament or hyphae. The hyphae are uniform all through the tapering at the ends. Such uniformity can help in recognizing it from the hair. These fungi will usually contaminate the dead cells of the epidermis.

The fungus dwells in an environment that is damp and warm. When heavy sweating occurs due to a humid environment, the oil of the skin which prevents fungal growth is washed off making the skin susceptible to infection. Men are usually affected compared to their female counterpart. This is due to the fact that men wear athletic supporters or tight underwear which is not washed immediately after every use. Also, people who sweat a lot and are overweight are at risk of developing the infection. Furthermore, those who are prone to this condition include individuals with diabetes, those with chronic, inherited skin disease atopic dermatitis and those suffering from HIV/AIDS.
