Symptoms of Ringworm

In the daily lives of most of us, we often encounter mosquito bites, especially in the hot summer. Because of the hot weather, many insects, including mosquitoes, like to come out and move around, so the human body is also very susceptible to harm from these mosquitoes at this time. After being bitten by a large number of mosquitoes, most people will only feel pain and itching in the bitten area, and there are no other symptoms.

In fact, sometimes due to poor physical condition, many people will suffer from related diseases, such as tinea corporis, in addition to itching and pain at the bite site after being bitten by mosquitoes. Of course, there are many other reasons why people may suffer from tinea corporis.

Now let's take a closer look at the symptoms of ringworm

In my country, this disease is mainly caused by Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton philoprolifera, Microsporum ferrugineum, and Microsporum canis. The disease can be caused by direct or indirect contact between the patient and the patient's contaminated bathtub, bath towel, etc. It can also spread from the patient's existing tinea manuum, tinea pedis, tinea cruris, tinea onychomycosis, tinea capitis, etc. The incidence of the disease is closely related to the body's resistance. Patients with diabetes, wasting disease, etc. are more likely to suffer from tinea corporis.

Clinical manifestations: Due to the large number of pathogenic fungi that cause tinea corporis, the different constitutions and resistance of each patient, as well as differences in hygiene habits, the clinical symptoms of tinea corporis vary. When pathogenic fungi invade the stratum corneum on the surface of the human body, they can cause a very mild inflammatory reaction, resulting in lesions such as erythema, papules, and blisters, followed by desquamation, which is often in a ring shape, hence the name tinea roundella or ringworm. At first the lesions are spread separately, but as they gradually expand, they may merge and overlap with each other, sometimes even affecting the whole body, especially in patients with immunodeficiency diseases or those taking immunosuppressants, corticosteroids, anti-tumor drugs, etc. The skin lesions may be extensive. Due to the body's defense ability, the center of the annular lesion can heal itself and desquamate, and the edges can be raised into a ring shape. There may also be active erythema, papules and blisters or desquamation, while the center is flat and desquamated or has pigmentation. Children's tinea corporis may appear in several circles, overlapping each other to form a wreath shape, which is a very special appearance.

Tinea manuum, tinea pedis, and onychomycosis are mainly caused by Trichophyton rubrum, Trichophyton mentagrophytes, etc. Tinea corporis caused by Trichophyton rubrum is often more prolonged and widespread, and is more common in the waist, abdomen, arms, trunk, etc., often accompanied by itching; tinea corporis caused by Trichophyton mentagrophytes tends to invade the cheeks and lower legs, often in annular or irregular shapes, and the inflammation is generally more obvious. Pustules or deep lesions may occur due to scratching, and local annular raised nodules may occur. The same fungus that causes tinea cruris, Epidermophyton floccosum, can sometimes cause tinea corporis. In addition to causing tinea capitis, Microsporum ferrugoides, Microsporum gypseum, Microsporum canis, Trichophyton rubrum, etc. can sometimes cause tinea corporis. The tinea corporis caused by the first three types of Microsporum often occurs on the forehead, cheeks, neck, upper limbs and trunk, and is often ring-shaped or multi-ring-shaped; the lesions caused by Microsporum gypseum are more scattered, with significant inflammation, and are often flushed; the initial lesions of tinea corporis caused by Trichophyton rubrum are often small, light red papules, which gradually expand and spread in an irregular shape, forming a map-like appearance.

Through the detailed introduction above, I believe most people have a certain degree of understanding of the general symptoms of tinea corporis. Therefore, in our future lives, whether tinea corporis is caused by mosquito bites or other reasons, we must go to the hospital for treatment as soon as possible, and then carry out relevant treatment after the doctor's diagnosis.
