Skin infections are caused by various pathogens, including bacteria, viruses, fungi, and parasites, leading to a wide range of clinical manifestations. Bacterial infections, such as impetigo and cellulitis, often result in red, swollen, and painful areas on the skin, sometimes accompanied by pus or other discharge.

Viral infections, like herpes simplex and warts, typically present with blisters, sores, or growths on the skin. Fungal infections, including athlete’s foot and ringworm, cause itchy, scaly, and sometimes ring-shaped lesions. Parasitic infestations, such as scabies, lead to intense itching and pimple-like rashes as the parasites burrow into the skin.

Treatment for skin infections depends on the type of pathogen involved. Bacterial infections are usually treated with antibiotics, either topical or oral, to eradicate the infection and reduce symptoms. Antiviral medications are prescribed for viral infections to control outbreaks and alleviate discomfort. Antifungal treatments, available in topical or oral forms, are used to treat fungal infections, often requiring several weeks to months of therapy. For parasitic infestations, antiparasitic medications are applied to the skin or taken orally to eliminate the parasites.
