There are a variety of skin rashes that are common and that you should be aware of to ensure you are safe. Some rashes look very similar to others, but some are extremely dangerous to your health, while others are harmless. Some rashes are caused by bacteria, while others are caused by viruses or even fungi. Below you will find some of the hallmarks of common skin rashes:
Shingles
This is also known as herpes zoster, which is a neurologic disorder caused by a virus. The skin gets red and has fluid-filled vesicles that look like blisters develop on the surface of the skin. This rash is unilateral and does not cross the midline.
Herpes simplex virus
This virus is a DNA-based virus and can be spread through direct contact. This HSV-1 virus usually targets the mouth or face and HSV-2 usually targets the genitals. This sore starts as a bump and ends up as a lesion that becomes concave in the center.
Tinea
This is a fungus that is named by the affected region of the skin. Tinea pedis is also known as athlete’s foot. Tinea corporis is the generic term for a skin rash on the body. Tinea cruris is also known as jock itch. These skin fungi are characterized by a red, scaly patch on the skin that is itchy in nature. There may also be a crust that forms on the border.
Hand-foot-and-mouth
This is a virus that is contagious rash usually found on palms of the hands and soles of the feet. There are also oral lesions. This rash usually affects children. Little red dots are present and a fever, headache, and sore throat are common symptoms.
Pityriasis rosea
This is a rash that occurs with a mother lesion, usually on the torso that ends up spreading daughter lesions. Etiology is unknown, but it is thought to come from a virus. The spots are bilateral and salmon-colored with a well-demarcated border.
Intertrigo
This rash is extremely red in color and found in skin folds. It occurs due to skin friction and lack of air circulation and can be worsened by yeast, bacteria, and even fungi. Symptoms include stinging, burning, and itching sensations and the condition is usually chronic in nature.
Cellulitis
This bacterial infection on the skin can cause redness and fevers, chills, pain, swelling, and tenderness in the reddened area. Borders are not demarcated and they are also not elevated.
Impetigo
This bacterial infection involves breakage in the skin that leads to an infection with blisters. The visible result is a sore that is depressed in the center.
Many rashes can present themselves in the same manner, which is why it is important to visit with your dermatologist. Your Batesville dermatologist can run tests to determine the etiology of the disease and with this information they can prescribe the proper course of treatment. Without proper diagnoses, the condition may worsen and can be passed on to others in your direct vicinity. If you need help with any of these conditions, call Dr. Patrick Hatfield's Batesville dermatological office.
