Tinea corporis ringworm is a superficial skin infection caused by fungi known as dermatophytes, so it is a fungal skin infection and it is a relatively common condition that occurs worldwide and it is an infection involving the neck, the trunk and the arms or the legs as opposed to other areas of the body like the feet or the groin which are different fungal skin infections and tinea corporis or ringworm is actually the most common dermatophyte infection in children, so what are some of the causative organisms, we know that they are fungi but what type of fungi? they are dermatophytes like trichophyton rubrum and trichophyton rubrum is actually the most common species of dermatophyte fungi that causes tinea corporis or ringworm, we can also see other trichophyton species causing this condition as well including trichophyton mentaiko phytase in trichophyton conference, it can also cause this like the microsporum species as well and we see microsporum canis coming from cats and dogs so cats and dogs that have microsporum canis that they can actually pass along to humans causing ringworm infection as well, how is this condition transmitted in winter? some of the risk factors is that the transmission of tinea corporis involves direct skin contact so this can either be through a direct skin-to-skin contact with an affected human or could be from an animal or it can be from the sand or soil so if there’s any fungi in the sand or the soil and you were to step on it or you were to contact your skin with that effected sand or soil, you could essentially pick this fungi up and lead to an infection and you can also have direct skin contact with fomites so formites are actually indirect objects like furniture, so if someone had tinea corporis fungal skin infection and they were to touch a table for instance and you came along and touch that table shortly after, you could technically pick up that fungi and there are some other infected sites as well, you can get it from auto infections so if you had a part of your body that had another type of infection, generally speaking the scalp so if you have a tinea capitis infection you could spread that tinea capitis fungi to other parts of your body.

What are some other risk factors, so some of risk factors for actually getting tinea corporis are the following; being in high humidity, in warm or hot environments, wearing tight fit clothing, so tight fitting clothes wearing them for a long period of time can increase your risk for getting this condition, you can also see this being common in children and individuals who are older and we can also see it in immunosuppressed patients, there is also a genetic predisposition to fungal infections in general, including tinea corporis individuals with decreased beta defensins or a decreased defence in beta for have been shown to be more susceptible to giving tinea infections. We can also see it with individuals who have systemic disease like diabetes and lymphoma, these are also associated with the immuno suppression, these conditions can cause immuno compromised and increase your risk for getting tinea corporis so what does tinea corporis look like, so tinea corporis is a circular or oval-shaped skin lesion and it occurs on most body surfaces like the trunk, the arms, the neck, the legs, except for the scalp, the hands, the feet and the groin.
