Skin infections caused by bacteria, viruses, and fungi are common. Often when someone gets a rash, they worry that it's an infection. Take a look at these pictures of rashes caused by various infections.

This is an example of a classic early chicken pox lesion, known as a dewdrop on a rose petal.

Note that there are clusters of vesicles on an erythematous base. These clusters usually grow together after a couple of days to make one distinct lesion.

While a fungal nail infection is not technically a skin infection, it is a common infection that causes people to seek medical treatment.

The medical names for fungal nails are onychomycosis and tinea unguium. Features of fungal nail infections you can see here include:

  • The nail separates from the nail bed.
  • The end of the nail turns yellow or white and debris forms under the nail.
  • The fungus grows into the nail, causing it to become fragile and crumble.

Rocky Mountain spotted fever (RMSF) is a potentially fatal disease that occurs most often in Oklahoma and the South Atlantic states, although it has been found in most states. It is caused by an infection with the bacteria Rickettsia rickettsii.

The rash associated with Rocky Mountain spotted fever usually starts around 4 days into the illness. It looks like small, red, flat spots starting most often on the ankles and wrists, and then moving to the palms, soles, and trunk. As the rash progresses, it becomes bumpier. Approximately 10% of those infected never get a rash.

The most common form of impetigo often occurs on the face or limbs and is known for its "honey-colored" crust, which you can see here. This crust often looks like small blisters. There is a less common form of impetigo that causes large blisters, called bullae. This form tends to occur more in newborns and younger children.

An ingrown toenail is caused by pressure of the nail against the skin on the side of the nail. A long period of pressure on the skin can cause irritation, pain, swelling, and infection of the skin.

Ingrown nails are usually seen on the big toes of people in industrialized nations. People in cultures that don't wear shoes rarely get ingrown nails.
