To Know About Skin Infection Types, Causes, and Treatment

Many pathogens can cause skin conditions, including infections caused by fungi, viruses, bacteria and parasites. The signs, symptoms and treatment options will be contingent on the underlying cause.

The severity of the infection can range from mild to very serious. The majority of skin infections are treated. But, an infection could get more serious in the event that it is deeper within the skin or spreads to most parts of your body.

Patients with a weak immune system are at an higher chance of skin infections as well as complications resulting from skin infections. This could be due:

  • A health issue that causes health problems, like HIV or poor circulation, diabetes, or malnutrition
  • A side effect of medications like chemotherapy or the use of biologic drugs
  • being very young or older
  • suffer from skin folds as a result of being overweight.

Drugs that are available over-the-counter as well as homemade remedies are often used to help with mild infections, but some infections might require medical treatment.

What is the different types of skin infection?

There are four distinct kinds of skin infection:

  • Skin infections caused by bacteria

Skin infections caused by bacteria are caused by bacteria that enter the skin whether from an external source or due to being found on your skin. The skin can be infected through hair follicles or after a cut.

Anthrax is one kind of bacterium that may enter from the outside. Staphylococcus Staphylococcus and Streptococcus Staphylococcus and Streptococcus are two types of bacteria which are typically found on the skin but can cause problems in specific situations. Lyme disease is a tick-borne illness which causes skin rashes.

Bacterial infections may be systemic or localized. The symptoms of systemic infections may be felt all over the body, including an illness that causes fever, while local infections affect only the affected area. Certain bacterial infections may begin within a specific area, and then extend all over the body.

Certain bacterial skin infections like impetigo can be transmitted between people via contact with the skin, bodily fluids, food items that are contaminated or water, or through touching surfaces on which the bacteria exist. Cellulitis, for instance aren’t contagious.

Different kinds of skin infections caused by bacteria are:

  • cellulitis
  • impetigo
  • boils
  • Hansen’s Disease (leprosy)

Infections that can cause skin rashes can include:

  • syphilis
  • tuberculosis
  • leptospirosis

Certain bacterial infections are not severe and can be treated by applying topical antibiotics. However, others require oral antibiotics or other treatment.

  • Skin infections caused by viruses

The virus can trigger a variety of skin manifestations, including:

  • shingles (herpes zoster)
  • chickenpox
  • Molluscum contagiosum
  • warts
  • measles
  • foot, hand as well as mouth illness

The viruses are typically transmissible, and the majority are systemic.

  • Fungal skin infections

Skin infections of this kind can be caused by the fungus that causes them and can be more likely to occur in humid areas of the body, where the skin and other surfaces come together, such as the armpits, feet, or in areas where there are folds in the skin.

In some instances there are instances where an allergy to the fungus may cause symptoms in other places that aren’t directly affected. For instance, someone suffering from a fungal infection on the foot may develop the appearance of a rash on their hands. This isn’t due to the fact that someone had touched their feet.

Different kinds of fungal diseases:

  • foot of an athlete
  • yeast infections
  • ringworm
  • nail fungus
  • oral thrush
  • diaper rash
  • Skin infection caused by parasitic

Skin infections of this kind result from the parasite. The infection can spread beyond the skin and into the organs and bloodstream. An infection caused by parasites isn’t serious, however it can be uncomfortable.

Different kinds of skin parasite conditions include:

  • lice
  • Bedbugs
  • scabies
  • cutaneous larva migrans

What exactly are signs of skin infections?

The signs of skin infections depend on:

  • The type of the
  • the root of the problem
  • specific factors, like the degree to which the individual has an immune system that is weak

The most common signs of skin infections are:

  • Redness that appears on pale skin or in darker or more purple skin areas if you have darker skin tones
  • lesions which could be raised or flat and wart-like. and so on.
  • Itching
  • Tenderness and pain

In rare instances the patient may suffer from other signs like an illness that causes fever.

A sign of a serious infection could include:

  • pus
  • blisters
  • skin breaking, sloughing
  • areas of darkness that may be a sign of the presence of necrosis or the death of tissue
  • Pain and discoloration
  • widespread swelling

Does this rash represent an infection or a different skin condition?

The causes and risk factors for skin infections

Certain kinds of pathogens including fungi and bacteria – are usually found within the pores but when they become many then the immune system will stop tackling them.

In this situation there is a risk of infection.

The reason for a skin infection is determined by the pathogen responsible.

Bacterial skin infection

These infections happen when bacteria get into the body via cuts through the skin for example scratch or cut.

Some scratches or cuts result in a skin infection however, there is more risk of getting it if you:

  • are immune systems that are weak
  • Don’t keep the cut free of dirt.
  • We are exposed to certain bacterial such as while working outdoors.

Viral skin infection

The most prevalent viruses originate from three distinct groups of viruses:

  • poxviruses, likeTrusted Source :
    • molluscum contagiosum
    • smallpox
    • Mpox
  • Human Papillomavirus (HPV), responsible for warts in the genital region
  • herpes viruses that can cause
    • herpex viruses (HSV)
    • varicella-zoster, a virus that can cause itchy shingles along with shingles
    • Epstein-Barr virus (EBV) which can result in mononucleosis.
    • Cytomegalovirus (CMV)

Experts aren’t sure how widespread infections can be on skin in contrast to the presence of fungi and bacteria.

Fungal infection

The body’s chemistry and the lifestyle could increase the risk of contracting a fungal infection. Fungal growth is most common in humid, warm and humid conditions.

The potential risk factors for a fungal infection include:

  • being sweaty on their feet, or who wear closed shoes
  • wear sweaty or wet clothes
  • the appearance of skin folds as a result of the body’s fat excess
  • Bathing in water that is contaminated
  • sharing personal belongings with other individuals with the fungus or are suffering from an infection

A cut or a break within the skin could allow pathogens to enter the layers beneath the skin.

Skin infection caused by parasitic

Small insects or other organisms that burrow under your skin and creating eggs could cause skin infections caused by parasites.

Some examples could include:

  • Scabies: A rash of mites that causes itching as well as a series of small pimples, lines on skin’s surface, as well as scales or crusty skin.
  • Pediculosis is an infection brought on by lice. It can trigger itching and lice and nitstheir eggs could be visible.
  • Creeping eruption: Usually caused by hookworms. This could cause a swell like a snake.


In most cases, doctors can determine the kind of skin condition by their appearance and place of origin.

The doctor might:

  • You can ask questions about symptoms
  • Check for any bumps, rashes or lesions.
  • Make a skin sample cells to test in the laboratory

When should you see an doctor

Visit a doctor if are suffering from:

  • Blisters stuffed with pus
  • massive or extensive swelling or swelling or
  • an infection of the skin that doesn’t get better or becomes more and more severe
  • an increase in fever or other signs
  • often-recurring or frequent rashes, or frequent or recurring rashes or

Skin infections can extend beyond the skin, and can spread to tissues beneath the skin or in the bloodstream, particularly for those with a weak immune system.

In the event of this, it can cause sepsis, which is a life-threatening illness.


The treatment is based on the root of the infection as well as its extent of the illness.

Certain infections can be treated by themselves or react to creams that are available at the pharmacy.

If the infection is serious and the patient is susceptible to complications or the infection may be infectious, a physician may prescribe medications, like:

  • Antibiotics
  • antivirals
  • antifungals
  • antiparasitics

The dosage of the medicine will be contingent on the degree of the infection or the possibility of complications. If a patient has a serious illness may require an extended period in the hospital.

The outcome will be based on the underlying cause, the nature, and severity of the disease.

Most skin infections respond to treatment. However, some conditions, such as methicillin-resistant Staphylococcus aureus (MRSA), are resistant to common antibiotics and harder to treat.

Prevention of skin infections

Strategies to lower the possibility of an rash or infection include:

  • Washing regularly
  • drying the body to get rid of any moisture
  • Avoid sharing personal items with people
  • monitoring the skin frequently for changes and seeking out advice whenever symptoms of infection begin to appear.
  • being vaccinated as recommended to protect against illnesses such as chickenpox

Commonly asked questions

What are the primary kinds of skin infection?

Skin infections could be:

  • Bacterial, usually caused by Streptococcal and Staphylococcal bacteria
  • infectious, such as warts, chickenpox, or even warts
  • fungal, as an example yeast infections, for instance.
  • parasitic, like parasitic, for example, scabies

What can a bacterial skin infection appear like?

It will vary based on the underlying infection, but is usually characterized by swelling and inflammation.

Which is the more frequent skin infection that is caused by a bacterium?

Impetigo is one of the most common examples of a bacterial disease. Other examples include cellulitis and Lyme disease.

The most prevalent bacteria that are that cause skin irritations is those belonging to the Staphylococcus as well as the Streptococcus species.


Skin conditions can result from fungal, viral, bacterial and parasitic causes. The manner in which they affect the body will be based on the particular pathogen. Certain cause skin irritation because of broader illness, whereas some cause only local symptoms.

Skin infections are usually treatable, but serious symptoms and complications can occur in people with an insufficient immune system.
