How to get rid of ringworm

What is ringworm?

Ringworm is an infectious skin disease caused by the parasitic fungi Microsporum canis and Trichophyton tonsurans, it is part of the group of ringworms that primarily affect the skin, hair and nails. This is an infectious dermatological pathology caused by dermatophyte fungi. It is also called dermatomycosis, scab, micro- and dermatophytosis.

Doctors distinguish several types of ringworm, depending on the location, nature of the course and the causative agent.

The main types of the disease are:

chronic or ringworm of smooth skin;
surface;
ringworm of the nail plate;
infiltrative-suppurative.

Since ringworm is caused by two types of fungi, in medicine it is diagnosed as microsporia and trichophytosis. These fungi have persistent pathogenicity, pronounced virulence and often cause acute diseases with varied clinical manifestations.

A disease caused by fungi of the genus Microsporum canis is microsporia. Depending on the location, there is microsporia of smooth skin and microsporia of the scalp.

Trichophytosis is caused by the activity of the dermatophyte Trichophyton tonsurans, which, through the anthroponotic route of infection, causes inflammation of the scalp and smooth skin, and through the zootroponotic route, inflammation in the deep layers of the dermis, accompanied by suppuration.

The presence of fungal spores does not always provoke damage to the skin and its appendages. The transition of the fungus from an inactive state to a pathogenic state is facilitated by metabolic and endocrine disorders, immune diseases, hypovitaminosis or vegetative-vascular dystonia. This increase in the pathogenicity of dermatophytes provokes an exacerbation of inflammatory processes, the spread of the fungus through the blood and lymph flow.

The disease is weakly expressed during the development of a latent infection and when localized in previously affected areas, and the high virulence of the fungus is formed during a relapse, gradually decreasing during the course of the infection.

Symptoms of ringworm: At the end of the incubation period, itchy ring-shaped spots of red-pink color appear on the skin, on the surface of which bubbles appear, after which a crust and peeling remain. The hair at the site of the lesion breaks and falls out.

Normally, the immune system is able to cope with the pathogen and prevent its activity, but there are a number of factors that increase the risk of ringworm, namely:

skin microtraumas;
lack of vitamins and microelements;
prolonged contact with the source of infection;
high humidity and air temperature;
exacerbation of chronic diseases, etc.

In a situation where there is an adult or child with lichen at home, it is necessary to take preventive measures to reduce the likelihood of its spread, namely:

use separate towels and bed linen;
wash your hands thoroughly with soap, especially if you touched the patient’s things;
use gloves when touching areas of disease;
undergo examination and take tests to identify pathogens, etc.

The main method for diagnosing ringworm is the use of a Wood's lamp, under the light of which the affected areas acquire a characteristic greenish glow. Microscopic examination and culture of skin and hair scales are effective to confirm the diagnosis.

Timely diagnosis and a properly selected treatment regimen can effectively eliminate ringworm in children and adults, preventing its spread. The pathology is prone to relapse, since the presence of spores of viable fungi can cause repeated damage. It is extremely important to complete the course of treatment and follow all doctor’s recommendations.

Is it possible to apply zinc ointment to pityriasis rosea?

Zinc ointment is a popular antiseptic with a softening effect. This remedy is indeed prescribed for the treatment of certain skin diseases, in particular eczema. But it is indicated for use in the treatment of rashes that produce exudate (that is, weeping ulcers), since it has a pronounced drying effect.

In the case of pityriasis rosea, there is no exudate; moreover, the plaque often flakes off and causes a feeling of tightness. The use of zinc ointment can intensify this unpleasant symptom. To improve the condition of the skin, you can use local preparations with a pronounced moisturizing effect. They often contain natural vegetable oils, as well as antiseptic components. But a dermatologist should select medications.

How is ringworm transmitted?

Ringworm is transmitted in two ways:

from a sick animal – zoonotic with an incubation period of one week;
from an infected person – anthroponotic with an incubation period of up to 6 weeks.

Children are at risk because they most often come into contact with the carriers of the pathogens of this disease - cats and dogs. Children's skin is characterized by low density of the stratum corneum and weak protective properties of the water-lipid mantle. The stratum corneum prevents the penetration of the fungus into the layers of the skin, since its spores are located between the horny scales, and the water-lipid mantle forms a barrier to the penetration of pathogens.

The infection is also transmitted by non-compliance with personal hygiene standards and the use of other people's personal belongings containing fungal spores (hats, combs, bed linen, etc.).

How does ringworm begin?

Favorable conditions contribute to the introduction and reproduction of a pathogenic fungus in the skin, triggering the infectious process. In the initial stages, this period is asymptomatic. After which the development of the pathology acquires clinical manifestations, the signs of which depend on the stage of the pathology.

The stages of the infectious process during the development of ringworm are:

incubation period;
period of mushroom growth;
refractory stage (period of insensitivity, rest);
regression.

In the skin, the fungus forms branched mycelium, which gradually invades new areas of the skin, while old lesions become the location of its spores. This period of fungal growth is determined by the rapid increase in the colony of the pathogen, active division of skin cells and the high rate of exfoliation of the affected epidermis.

Since most often the growth of the colony outstrips the rate of change of the stratum corneum, the infectious process spreads. An intense immune reaction (inflammation) in the lesion is displayed in the form of a red ring, which, in the chronic course of mycosis, becomes the permanent residence of the pathogen.

Where does shingles occur?

The location of the rash depends on which nerve is affected. The rash may appear on the face, torso, and limbs, but usually only on one side of the body: for example, only on the back or only on the stomach. If vesicles appear on both sides, this indicates a rare generalized form of herpes zoster.

The rash may also affect:

ears;
mucous membrane of the mouth and nose;
conjunctiva of the eyes;
external genitalia, including the vulva in women.

If bubbles appear on the mucous membranes, they quickly burst with the formation of areas of erosion.

What does ringworm look like?

Clinical manifestations of ringworm depend on the type of pathogen, course and stage of the disease. Dermatophytes secrete enzymes and toxins that destroy keratin protein (they feed on it), so the severity of symptoms directly depends on the ability of fungi to produce these substances.

Common symptoms of ringworm on the scalp are:

hair thinning;
the appearance of localized peeling of the skin;
redness of the epidermis;
hair breaking off at the root;
the appearance of small bubbles with cloudy contents along the edges of bald patches, after opening which yellow crusts form.

Ringworm of smooth skin includes the following symptoms:

pronounced itching;
the appearance of round red spots;
light epidermis at the site of damage, surrounded by gray scales;
the edges of the damaged area consist of pink-red bubbles;
growth of the lesion in diameter.

The chronic form of the disease is accompanied by the presence of microscopic blisters on the affected areas, the formation of scars after their opening and severe itching. In a situation where the site of the lesion is the nail plate, its separation, discoloration and thickening are observed.

Ringworm of the infiltrative-suppurative form is characterized by the appearance of large bright red spots up to 10 cm in diameter, the outer surface of which is lumpy and uneven, and purulent follicles form along the edges. Pain, swelling and hyperemia of the affected areas are also observed.

The appearance of the first signs of the disease requires a mandatory visit to a dermatologist. The lack of qualified treatment can lead to the rapid spread of infection throughout the body and cause a number of complications: tissue scarring, death of hair follicles, allergic reactions and the addition of a secondary infection.

Why can't you scratch pityriasis rosea?

Zhiber's pityriasis rosea can occur without symptoms, including without skin irritation. But some patients suffer from itching in the area of the rash. As with other dermatoses, you should not scratch the site of infection.

Violation of this rule leads to:

damage to the top layer of skin and the appearance of scratches;
the risk of introducing bacterial flora into the plaque, which will cause inflammation and suppuration of the tissue;
increase in the area of rashes.

To cope with itching and skin irritation, seek help from a dermatologist or dermatovenerologist. The doctor will select corticosteroid ointments to relieve inflammation and antihistamines to relieve itching and burning.

How is ringworm treated?

In each case, treatment for ringworm should be selected individually, since its composition and duration have their own specifics and are determined by the type, location and stage of the pathology.

Only prescriptions from a dermatologist are effective; they take into account the current clinical picture, the characteristics of the patient’s physical health and his age.

Therapy is aimed not only at relieving the symptoms of the pathology, but also at inactivating the pathogen. The chronic form of the disease also provides support for the immune system, normalization of metabolism and hormonal levels.

The following groups of drugs are used to treat ringworm:

systemic and local antimycotics;
antiseptic solutions;
multivitamin complexes.

Is it possible to cure pityriasis rosea permanently?

Many patients, faced with a recurrent disease, are interested in whether it is possible to get rid of pityriasis rosea forever? It is possible if you consult a dermatologist. The doctor will not only select highly effective medications to eliminate rashes and itching, but will also develop preventive recommendations to prevent relapse.

Typically, the treatment regimen for pityriasis rosea includes the use of the following medications:

local ointments with corticosteroids: act simultaneously on several levels - relieve skin tightness, promote rapid healing of the rash;
antihistamines – eliminate itching;
immunomodulators - activate natural defense mechanisms to combat pathogens.

Additionally, a dermatologist may prescribe treatment of rashes with antiseptic solutions to prevent secondary infection by bacteria, as well as emollient ointments for severe peeling.

Following medical recommendations will allow you to quickly recover and forget about Zhiber’s disease forever.

How long does it take to treat ringworm?

The treatment process for ringworm is lengthy, usually taking at least six weeks, with systemic therapy lasting mainly 15-25 days.

The effectiveness of therapy is assessed using laboratory tests. In a situation where tests indicate a significant decrease in the number of fungal spores after 2 weeks of a medication course, it is necessary to continue the chosen treatment. In some cases, fungal shedding can last for several months.

After the signs of pathology disappear, you need to scrape the epidermis three times in previously damaged areas:

immediately after completion of therapy;
7 days after therapy;
after 2-3 months.

The result of therapy is considered successful if all three tests show negative results.

How to treat ringworm in children?

Treatment of ringworm in a child is the responsibility of a pediatric dermatologist, since the characteristics of the child’s body require special doses and composition of medications.

Hygiene and child care are also important elements of pathology therapy:

boiling and ironing clothes in contact with affected areas of the skin;
treating household surfaces with disinfectants to prevent the spread of spores;
frequent change of bed linen;
washing in the shower rather than the bath, etc.

Preventive measures

Prevention of ringworm is based on regular medical examinations of children attending preschool educational institutions. Parents should talk to their children about the inadmissibility of contact with stray animals. An important preventive measure is compliance with personal hygiene rules by patients of all age groups.

When purchasing pets, you must visit a veterinarian. The doctor will examine the cat or dog and give recommendations on how to eliminate any health problems with the pet. Following your veterinarian's advice will help prevent microscopic outbreaks within your family.

Can I go to work or school with ringworm?

The presence of this diagnosis requires isolation of the patient from the team for at least two weeks. In schools and other children's institutions, it is mandatory to notify parents for timely detection of the disease in other children.

The disappearance of ringworm symptoms and 3 negative tests for the presence of fungus are a reason to return to school or work.

If a dermatomycosis infection has been detected in a team, then to prevent pathology, you can use antifungal shampoos for some time, carry out wet cleaning with the addition of antiseptic solutions, and strictly observe personal hygiene.

Treatment

The combination of drugs prescribed to the patient depends on the severity of damage to the skin, nail plates and hair follicles. Antifungal therapy may be local or general. In the first case, a child or adult needs to use creams and ointments that suppress the activity of the microsporia pathogen. Drugs in this group are not recommended for use by girls during pregnancy and lactation. Topical sprays are effective in treating large areas of ringworm. Modern formulations do not leave stains on the skin and are not absorbed into the fabric of clothing.

A severe inflammatory reaction is treated with a combination of antifungal and hormonal drugs. Patients will have to apply ointment applications to the affected areas. After this, the skin is treated with iodine solutions. The oral tablet intake schedule is formed by a dermatologist based on the clinical picture of the pathology.

The addition of a secondary infection to microsporia involves the use of drugs based on betamethasone, gentamicin or clotrimazole.
