Certain bacteria commonly live on the skin of many people without causing harm. However, these bacteria can cause infections if they enter the body through cuts, open wounds, or other breaks in the skin.

Bacterial skin infections often begin as small, red bumps that slowly increase in size. Some bacterial infections are mild and easily treated with topical antibiotics, but other infections require an oral antibiotic. Different types of bacterial skin infections include cellulitis, impetigo, boils and leprosy.

Bacterial infections can look different depending on the infected area, the type of bacteria, and person’s age.
