Overview of skin infections

Overview[edit]

Cellulitis of the left leg

A skin infection is an infection of the skin and its underlying soft tissues. Skin infections can be caused by a wide variety of pathogens, including bacteria, viruses, fungi, and parasites. They can range from mild to severe and can affect any part of the body.

Types of Skin Infections[edit]

Skin infections are generally categorized based on the type of pathogen causing the infection:

Bacterial Skin Infections[edit]

Bacterial skin infections are caused by bacteria and are often characterized by redness, warmth, swelling, and pain. Common bacterial skin infections include:

Cellulitis: A deep bacterial infection of the skin and subcutaneous tissues, often caused by Streptococcus or Staphylococcus species. It typically presents with redness, swelling, and tenderness of the affected area.
Impetigo: A highly contagious superficial skin infection, often seen in children, characterized by honey-colored crusts.
Folliculitis: An infection of the hair follicles, often caused by Staphylococcus aureus.

Viral Skin Infections[edit]

Viral skin infections are caused by viruses and can present with a variety of symptoms, including rashes and blisters. Examples include:

Herpes simplex: Causes cold sores or genital herpes.
Varicella zoster virus: Causes chickenpox and shingles.

Fungal Skin Infections[edit]

Fungal infections of the skin are often caused by dermatophytes, yeasts, or molds. Common fungal infections include:

Tinea (ringworm): A group of diseases caused by dermatophytes, affecting various parts of the body such as the scalp (tinea capitis) and feet (tinea pedis).
Candidiasis: Caused by Candida species, often affecting moist areas of the body.

Parasitic Skin Infections[edit]

Parasitic infections of the skin are caused by parasites such as mites and lice. Examples include:

Scabies: Caused by the mite Sarcoptes scabiei, leading to intense itching and a pimple-like rash.
Pediculosis: Infestation with lice, affecting the scalp or body.

Diagnosis[edit]

Diagnosis of skin infections typically involves a clinical examination and may include laboratory tests such as cultures, skin scrapings, or biopsies to identify the causative organism.

Treatment[edit]

Treatment of skin infections depends on the type and severity of the infection. Options may include:

Antibiotics for bacterial infections
Antiviral medications for viral infections
Antifungal treatments for fungal infections
Topical or oral antiparasitic medications for parasitic infections

Prevention[edit]

Preventive measures for skin infections include maintaining good hygiene, avoiding contact with infected individuals, and using protective clothing or barriers when necessary.

+{{Short description|Overview of skin infections}}
+{{Medical resources}}
-Skin infections are a broad category of conditions that involve the invasion of the skin by pathogenic microorganisms. These infections can be caused by a variety of microorganisms, including [[bacteria]], [[viruses]], [[fungi]], and [[parasites]]. Skin infections can range from mild to severe and can affect individuals of all ages. Understanding the different types of skin infections, their causes, symptoms, and treatment options is essential for effective management and prevention.

-Skin infections are classified based on the causative agent. The main types include:
+=== Bacterial Skin Infections ===
+Bacterial skin infections are caused by bacteria and are often characterized by redness, warmth, swelling, and pain. Common bacterial skin infections include:
-===Bacterial Skin Infections===
+* [[Cellulitis]]: A deep bacterial infection of the skin and subcutaneous tissues, often caused by [[Streptococcus]] or [[Staphylococcus]] species. It typically presents with redness, swelling, and tenderness of the affected area.
-Bacterial skin infections are caused by bacteria. Common examples include [[Impetigo]], which is highly contagious and often affects children, and [[Cellulitis]], a deeper infection that involves the skin's underlying tissue. [[Folliculitis]], the inflammation of hair follicles, is another example, often caused by ''Staphylococcus aureus''.

-Viral infections of the skin are caused by viruses. Examples include [[Herpes Simplex Virus]] (HSV) leading to cold sores or genital herpes, and [[Varicella Zoster Virus]] (VZV), which causes chickenpox and shingles. [[Human Papillomavirus]] (HPV) can cause skin warts.
+Viral skin infections are caused by viruses and can present with a variety of symptoms, including rashes and blisters. Examples include:

+* [[Herpes simplex]]: Causes cold sores or genital herpes.
-Fungi can cause skin infections known as [[Dermatophytosis]] or ringworm, which can affect various parts of the body, including the scalp ([[Tinea Capitis]]), body ([[Tinea Corporis]]), feet ([[Athlete's Foot]]), and nails ([[Onychomycosis]]). [[Candidiasis]] is another fungal infection, often affecting warm, moist areas of the body.
+* [[Varicella zoster virus]]: Causes chickenpox and shingles.
-===Parasitic Skin Infections===
+=== Fungal Skin Infections ===
-Parasitic infections involve parasites invading the skin. [[Scabies]], caused by the mite ''Sarcoptes scabiei'', and [[Lice]] infestations are common examples. These infections are characterized by intense itching and skin rash.

-Symptoms of skin infections vary depending on the type of infection but may include redness, swelling, pain, warmth, pus, blisters, and itching. Some infections, like cellulitis, can also cause fever and chills.
+* [[Candidiasis]]: Caused by [[Candida]] species, often affecting moist areas of the body.
-==Diagnosis==
+=== Parasitic Skin Infections ===
-Diagnosis of skin infections typically involves a physical examination and medical history. In some cases, laboratory tests such as cultures, skin biopsies, or blood tests may be necessary to identify the causative agent.
+Parasitic infections of the skin are caused by parasites such as mites and lice. Examples include:
-==Treatment==
+* [[Scabies]]: Caused by the mite [[Sarcoptes scabiei]], leading to intense itching and a pimple-like rash.
-Treatment depends on the type of infection and its severity. Bacterial infections are usually treated with [[Antibiotics|antibiotics]], either topical or oral. Viral infections may require antiviral medications, while antifungal creams or oral medications are used for fungal infections. Parasitic infections are treated with specific antiparasitic drugs.
+* [[Pediculosis]]: Infestation with lice, affecting the scalp or body.
-==Prevention==
+== Diagnosis ==
-Preventive measures include practicing good hygiene, keeping the skin clean and dry, avoiding sharing personal items, and using protective barriers when in contact with potentially infectious materials. Vaccinations can also prevent certain viral skin infections.
