What Is a Skin Infection?<\/strong><\/h2>\n\n\n\n

A skin infection occurs when bacteria, viruses, fungi, or parasites<\/strong> enter the skin and begin to multiply. This leads to symptoms such as redness, swelling, pain, warmth, itching, or pus formation<\/strong>.<\/p>\n\n\n\n

Depending on the cause, skin infections can range from mild to severe.<\/p>\n\n\n\n

\n\n\n\n
