Learn about typical infectious dermatitis

Most dermatological diseases are usually mild, can be treated with simple methods such as over-the-counter and prescription medications combined with topical cleaning methods, which can be cared for at home.

But if the patient has a severe skin infection, medical intervention is required with an appropriate regimen as directed by a specialist.

Human skin is considered a fertile ground for many types of bacteria, even parasites, and fungi that cause disease. According to medical studies, there are about 1 million microorganisms per square centimeter of skin. Common types of bacteria that cause skin diseases such as streptococcus and staphylococcus.

Under normal conditions, these bacteria will not cause disease on the skin, but when there are favorable conditions such as weakened immune system, poor body hygiene, sweat glands are active, sweat a lot. or a hot, itchy environment, trauma to the skin, suffering from some diseases such as diabetes … will cause these bacteria to increase their toxicity and infiltrate causing skin infections, typically purulent dermatitis.

Bacterial dermatitis caused by staphylococcus

In addition, the use of shower creams but not paying attention to clean the soap bubbles makes the chemicals in the shower gel still remain on the skin, making the skin itchy, uncomfortable, and can cause serious effects. important to the skin.

Pustule Dermatitis caused by Staphylococcus aureus

Staph is a bacteria that often causes damage to the hair follicles. The typical purulent dermatitis forms are as follows:

Shallow Folliculitis

Folliculitis is a superficial inflammatory disease, usually at the tip of the pore. At the beginning of the disease, these pores will be slightly swollen and red, making the patient feel pain. As the disease continues to develop, small pustules will form around the hairline and narrow inflamed pants.

What is the pathology of folliculitis?

A few days later, the pustules will dry and leave on the scaly, dark brown skin. This scab will eventually peel off but leave no scars.

Deep folliculitis will cause physical manifestations on the patient's body, including follicles, which become swollen in clusters, and around the pores will form pustules. For this pustules can grow in clusters or scattered with a hard, red, rough look, when squeezed, there will be pus.

Deep folliculitis is a condition that usually occurs in areas such as the back of the neck, chin, or scalp. The disease usually has a long progression and often recurs many times.


Furunculosis is also one of the typical infectious dermatitides. In this case, the large, growing boils can cause fever, nearby lymph nodes causing painful swelling.

For boils growing in the ear often cause a very painful feeling, according to the folklore is called "overside" disease. As for boils growing around the mouth, also known as "beard nail", this is a very dangerous condition because it can block the veins, leading to septicemia, increasing the risk of death.

Nail boils usually grow in the back, buttocks, and nape positions due to the cause of a highly toxic staphylococcus, which is common in the elderly, people with diabetes, alcoholics, and poor appetite.

When this pus ruptures, there will be many holes in the hole like a honeycomb, which can easily cause dangerous complications such as sepsis and death if not controlled well.


One of the next typical folliculitides is a pothole, often accompanied by inflammation of the sweat glands or sebaceous glands in the armpit. These agents will form a deep purulent sac in the dermis and dermis.

A pothole causes a lumpy lesion that usually occurs in the armpit area. At first, the boil will harden, but later it will soften and begin to rupture pus.

Depending on the situation, there may be one or more potholes present in the same axillary fossa. This disease is a persistent progression, often recurs many times, and occurs very often in the summer when the weather is too hot.

Pustule Dermatitis caused by Staphylococcus aureus

There are many types of bacteria on human skin, mostly streptococci, and staphylococci, often concentrated in hairy areas, sweat, or sebum … especially when exposed to a dusty environment. dirty. In post-flood areas, people who frequently have to wade in dirty water are more susceptible to atopic dermatitis.

Bacterial dermatitis caused by streptococcus

Like staphylococci, streptococci are bacteria found on the surface of human skin, when encountering favorable factors will make them thrive and cause disease on the skin. Besides, streptococci present in dirty water environments can also penetrate the skin causing disease.

For streptococcal infectious dermatitis often includes the typical diseases such as:


The most common infectious dermatitis in children is transient. This is a common pathology caused by both agents, the association with the staph, the disease.

It usually occurs in the position of head, face, neck, and extremities and then spreads to other places if not treated well. Also known as a contagious disease.

Immediately will cause early lesions as small, round, inflamed blisters.

At first, these blisters will clear but later turn to cloudy pus. Breaking time of blisters or pustules is quite short. Then will form a yellow secretion, below the scale will be a layer of red slippery, not touching and quite shallow.

For young children, the most common type of moment is when the head grows into rocks, has a dark yellow scaly, causing sticky hair. Underneath the scaly red, slightly oozing skin. When there are instant lesions scattered all over the body, it may be accompanied by fever and lead to complications of swelling of the eyelids and legs caused by acute glomerulonephritis.

For children with infectious dermatitis in the case of a lot of scales, the doctor will wash the wound with an antiseptic solution, then apply a bandage.

When there is pus that has not been broken yet, it may be necessary to use an antiseptic needle to poke the pus out and then soak it in the cotton, in order to prevent the pus from reaching other healthy areas.

Impetigo (Ecthyma)

Impetigo is an immediate cause of deep damage to the dermis, usually occurs in the lower extremities, commonly found in the limbs with varicose veins and more in people who are malnourished, have diabetes, and have a long-term alcohol addiction. years or poor hygiene.

When the ulcer develops, it causes blisters or pus-filled puffiness, which then break open, form a thick, scaly, dark yellow color, or turn dark brown. On this scab will form raised extruded layers known as snail scales.

When peeling this layer away, it will leave a pus-filled sore, with a pale background, fewer meat buds. Look around the ulcer purple color, progresses quite persistent and the recovery process takes time.

If the patient has severe or prolonged ulcers, it can form deep, oval, wide, deep ulcers with clear boundaries, the organization around this wound are pale, sclerotic, and progressing. Severe ulcers are usually persistent.

To treat ulcers, doctors often use 1/4.000 purple medicine solution or 0.25 – 0.50% silver nitrate solution to dab on the ulcers. In addition, antibiotic ointment can be applied or oral or oral antibiotics are required.


Interstitial is common in people with active sweat glands, obese people, or young children. When it is interstitial, it will cause damage in the groin area, neck folds, navel, skin lines, or behind the ears. These folds are red, oozing, the outer part often has a thin skin border, watery or pus that causes burning pain.

Interstitial interstitial is common in young children

Angular Cheilitis

Immediately the edge makes the edges crack, oozing, then yellow scabs, causing burning pain, easy to bleed, making eating and drinking difficult.

Learn about mouth disease

The disease can be spread when sharing a washcloth, drinking water from the same cup with the sick person, or embracing … To treat terminal illness, it is necessary to use antibiotic ointment or a 0.25% silver nitrate solution as directed by a doctor.

As such, infectious dermatitis would cause varying degrees of severity. As soon as there are abnormal symptoms, the patient should quickly go to the hospital to diagnose, find the cause, and have an effective treatment regimen to help improve symptoms well.
