Skin infections can be caused by a variety of pathogens, including bacteria, viruses, fungi, and parasites. The specific cause of a skin infection will determine its symptoms, treatment, and prognosis.
Here are some common causes of skin infections:
- Bacteria: Staphylococcus and Streptococcus are among the most common bacteria that cause skin infections. These bacteria are often found on the skin and can enter the body through a break, cut, or wound. They can also cause infections in areas where the skin rubs together, especially if the area is moist.
- Viruses: Viral skin infections can be caused by various viruses, such as the herpes simplex virus (HSV), the varicella-zoster virus (VZV), and the human papillomavirus (HPV).
- Fungi: Fungal skin infections, also known as mycoses, are caused by fungi that live in the environment. They can cause rashes, ulcers, and other symptoms on the skin. Subcutaneous fungal infections are more common in tropical and subtropical areas of the world.
- Parasites: Parasites can also cause skin infections, such as scabies and lice.
The symptoms of a skin infection can vary depending on the type of infection and its severity. Common symptoms include:
- Redness
- Swelling
- Pain
- Itching
- Pus
- Scaling
- Blisters
If you suspect you have a skin infection, it is important to see a doctor for diagnosis and treatment. Treatment will typically involve antibiotics, antiviral medications, antifungal medications, or antiparasitic medications, depending on the cause of the infection.
