Skin infections occur when harmful microorganisms, such as bacteria, fungi, viruses, or parasites, invade the skin. They can cause redness, itching, swelling, pain, or blisters. Common types of skin infections include bacterial ones like cellulitis, fungal infections like athlete’s foot, viral conditions such as warts, and parasitic infestations like scabies.

Skin infections often happen through cuts, scrapes, or insect bites that allow germs to enter. Poor hygiene, a weakened immune system, or close contact with an infected person can increase the risk.

Treatment depends on the cause. Bacterial infections may require antibiotics, while antifungal creams are used for fungal issues. Viral infections often resolve naturally, but some need antiviral medication. Parasitic infections are treated with specific medications.

Preventing skin infections involves proper hygiene, protecting skin from injuries, and avoiding sharing personal items. Prompt treatment is important to stop infections from spreading or worsening.
