Tinea corporis is a superficial fungal infection caused by pathogenic fungi parasitic on the smooth skin of the human body. When pathogenic fungi invade the stratum corneum on the surface of the human body, they can cause an inflammatory reaction, causing damage such as erythema, papules, and blisters. So what are the causes of tinea corporis?
Contact with people with ringworm
Because tinea corporis is contagious, direct contact with patients is also an important cause of tinea corporis, and even contact with some livestock-affected animals such as dogs and cats, thus causing tinea corporis.
Self-infection
Prior suffering from ringworm of the hands, feet, onychomycosis, etc., resulting in infection inducing tinea corporis. People who wear airtight clothing, are obese and sweaty, or drivers are susceptible to jock itch.
Seasonal environmental factors

Caused by drugs or chronic diseases
Due to the long-term use of glucocorticoids, broad-spectrum antibiotics, and a large number of immunosuppressants, the body's immunity is low, resulting in the invasion and infection of dermatophytes. Diabetes mellitus and chronic wasting disease are also important factors in the cause of tinea corporis.
Pathogenic bacteria
Tinea corporis is caused by pathogenic bacteria, and the causative fungus is dermatophyte, which is characterized by exfoliation. The most common pathogenic fungus is Trichophyton rubrum, but others include tinea barbae, Trichophytonium, Microsporum canis and Microsporum gypsumiform.
Tips
It is mainly transmitted by contact, and can be transmitted from person to person, animal to person, contaminant to person, and between different parts of the human body, such as through everyday objects such as nail clippers, shoes and socks, bathtubs and towels.
