What are the symptoms of eczematous dermatitis contagious?

Infectious eczema dermatitis is a common infectious skin disease. It takes a long time to treat this disease and requires attention to daily hygiene. The symptoms of infectious eczematous dermatitis are relatively obvious, and everyone should be able to discover them in time.

Symptoms of infectious eczematous dermatitis

Early symptoms: Sometimes the earliest lesions are ruptured abscesses, furuncles, carbuncles, sinusitis, chronic otitis media, bedsores, fistulas, scabies or ulcers, or they may be focal infections of the nose, eyes or vagina.

Late symptoms: Extensive dermatitis may also occur elsewhere on the body due to autosensitivity reactions. Some patients often develop linear or strip-shaped eczematous dermatitis due to scratching. The rash is often asymmetrical and has severe itching, but is generally milder than eczema.

1. Symptoms

There is a chronic suppurative infection before the rash. The primary focus may be a blister or pustule, or an inflamed papule with scales or crusts, or a moist red spot, which often occurs symmetrically on the exposed part. Sometimes the earliest lesions are ruptured abscesses, furuncles, carbuncles, sinusitis, chronic otitis media, bedsores, fistulas, scabies, or ulcers, or they may be focal infections of the nose, eyes, or vagina. Often when local lesions worsen, erythema, papules, blisters, pustules, and scabs appear on the skin around the infection focus, and gradually spread outward to become patches of eczematous dermatitis that ooze serous pus and have scabs on the surface. When symptoms are mild or inflammation subsides, the affected area becomes dry and scaly. In severe cases, the affected area may swell, erode, exude, and have obvious erythema, papules, small blisters, pustules and other acute eczematous changes on the periphery, becoming eczematous patchy skin lesions with irregular borders. Regional lymph nodes are often enlarged, and occasionally there is a fever. Generalized dermatitis may also occur elsewhere on the body due to autosensitivity reactions. Some patients often develop linear or strip-shaped eczematous dermatitis due to scratching. The rash is often asymmetrical and has severe itching, but is generally milder than eczema.

2. Diagnosis

This disease occurs on the basis of infected lesions, and erosion of the surrounding skin occurs. The characteristics of acute eczematoid lesions such as blisters and pustules are not difficult to diagnose, but they must be distinguished from contact dermatitis, eczema, impetigo and seborrheic dermatitis.
