A rash is a temporary eruption or discoloration of the skin and is often inflamed or swollen. Rashes come in many forms and levels of severity, and they last for different amounts of time. Some common causes of rashes include: 1. Infections — This broad category covers a wide range of illnesses, including: 1. Viral infections, such as measles, rubella, roseola, fifth disease, varicella zoster, herpes or shingles 1. Bacterial infections, such as impetigo, scarlet fever or Lyme disease 1. 1. Fu...
Although rash is easily recognized, all rashes are not the same. Rashes vary in their appearance, timing, location or distribution, and duration. In general, rashes can be described as: 1. Macular — Flat, red spots 2. Papular — Small, raised, solid bumps 3. Macular and papular — A combination 4. Papulosquamous — A combination of papules and scaly areas 5. Vesicular — Small, raised, fluid-filled blisters Additional signs and symptoms that sometimes accompany rashes include: 1. Fever 2. Swollen...
Your doctor will ask you about your medical history, including your history of allergies and your work history, to check for possible exposure to chemical irritants or to people with infections. Your doctor also may ask specific questions about your rash, including: 1. When it began — Did the rash appear after you ate a new food, tried a new skin care product or took a new medication? 2. Location and pattern — Does the rash affect only sun-exposed areas or only areas in direct contact with gl...
How long a rash lasts depends on its cause. However, most rashes usually disappear within a few days. For example, the rash of a roseola viral infection usually lasts 1 to 2 days, whereas the rash of measles disappears within 6 to 7 days. Rashes caused by an antibiotic allergy may last 3 to 14 days, whereas diaper rash almost always clears up within 1 week (if diapers are changed frequently).Rashes resulting from lupus or dermatomyositis may last for an extended period of time.
Prevention depends on the cause of the rash: 1. Infections — Check that you and your children are up-to-date in your routine immunizations. Wash your hands frequently, bathe regularly and avoid sharing clothing or personal grooming items with other people. To prevent Lyme disease, wear light-colored clothing that contrasts with the dark tick and covers most of your skin when you go into the woods. Use approved tick repellents. Be aware that you are more likely to be exposed to ticks in areas...
Treatment depends on the cause of the rash: 1. Infections — Bacterial infections are treated with antibiotics. Fungal infections are treated with antifungal medications. Many viral infections that cause rash will go away within several days and require no medication. Less often, antiviral drugs are necessary. 2. Allergic reactions — A severe allergic reaction is a life-threatening medical emergency. It must be treated immediately with epinephrine, a medication that opens narrowed airways and...
Seek immediate medical attention if you begin to have difficulty breathing or develop hives, a fever, a fast pulse, confusion or nausea. These could be signs of a life-threatening allergic reaction. Always consult your doctor promptly if a rash: 1. Worsens 2. Lasts longer than one week 3. Shows signs of local infection (oozing, redness or swelling of the skin) 4. Occurs together with fever, chills, swollen glands or other symptoms of infection (sore throat, cough, headache, nasal congestion,...
The outlook for most rashes is excellent, especially after the cause has been identified accurately. In severe allergic reactions, a patient can die within minutes without immediate medical treatment. With proper treatment, recovery usually is complete. However, the patient remains at risk of future severe reactions if he or she is exposed to the same allergy-producing agent. For this reason, a prescription for a self-injection pen containing epinephrine for emergencies usually is recommended...

Rash is not a specific diagnosis. Instead, it refers to any sort of inflammation and/or discoloration that distorts the skin's normal appearance. Common rashes include COVID-19 rash, eczema, poison ivy, hives, and athlete's foot. Infections that cause rashes may be fungal, bacterial, parasitic, or viral.
A rash is not a specific diagnosis though. It is a symptom of an underlying medical problem and the key to treating a rash is to first identify what is causing it. MinuteClinic® providers can evaluate your rash and work with you to develop a treatment plan to not only address pain and discomfort, but to help ensure that you do not develop an infection or have long-term problems due to your rash.

Noninfectious rashes include eczema, contact dermatitis, psoriasis, seborrheic dermatitis, drug eruptions, rosacea, hives (urticaria), dry skin (xerosis), and allergic dermatitis. Many noninfectious rashes are typically treated with corticosteroid creams and/or pills. Even a noncontagious, noninfectious rash can cause discomfort and anxiety.
Infection-associated rashes, such as ringworm (tinea), impetigo, Staphylococcus, scabies, herpes, chickenpox, and shingles, are treated by treating the underlying cause. Infectious agents that can cause a rash include viruses, bacteria, fungi, and parasites. The reported history will help characterize the duration, onset, relationship to various environmental factors, skin symptoms (such as itching and pain), and constitutional symptoms such as fever, headache, and chills. Based on the health-care provider's initial impression of a rash, treatment may be started. The treatment may need to be modified pending various laboratory and special skin examinations. In general, most noninfectious rashes are usually treated symptomatically and often with cortisone creams and/or pills. Infection-associated rashes are frequently treated by addressing the underlying infection. Some treatments, such as oatmeal baths, may help control the itching of both infectious and noninfectious rashes.
Many different risk factors determine what rash or rashes a patient might get. A family history of eczema, frequent exposure to sick children, necessary use of immunosuppressive medications, and exposure to multiple medications all increase the risk of developing rashes.
A careful drug history that includes over-the-counter (OTC) medications, supplements, and prescription drugs such as birth control pills is also important. The timing of when medications are started and stops may provide important clues for establishing the cause of a rash.
There are some rashes that only appear in association with pregnancy, either during pregnancy or even after the delivery of the baby. Most of these are not serious but can be very irritating.
Dermatologists (skin specialists) are best equipped to diagnose and treat most rashes, especially those that require biopsy or special tests. Unfortunately, there may be quite a delay in obtaining a dermatologist consult in some areas. For that reason, most primary-care physicians (family physicians, internists, and pediatricians), as well as those who work in urgent care and emergency departments, will be the first to see a patient's rash and, in many cases, can make accurate diagnoses and advise effective treatment. Allergists treat many rashes also, especially those related to hives. Occasionally, an infectious-disease specialist may be involved in the treatment of rashes caused by severe or unusual infections. Medical or surgical oncologists may have a role when a skin rash is due directly or indirectly to an underlying cancer. Sampling skin material and viewing under direct microscopy is a fast and simple way to help confirm or eliminate fungus as a cause of the rash. When a superficial fungal or yeast infection is suspected, viewing a superficial skin scraping with a potassium hydroxide prep can reveal fungal hyphae or budding cells. Prior treatment with antifungal creams may cause a false-negative test. Blood tests can be helpful as well (for example, sudden onset of severe psoriasis may be associated with an HIV infection). Anti-streptolysin O (ASO) levels can be helpful in detecting a sudden onset of guttate psoriasis associated with a recent streptococcal throat infection.
The outlook for rash depends on the underlying cause. The prognosis of clearing a superficial fungal infection is very good while a patient with psoriasis or eczema may not clear completely despite aggressive therapy. Most rashes are short-lived and easily resolve. There are some chronic rashes that are not curable, such as psoriasis. Medical monitoring is often necessary to watch the progression of more resistant or recurrent rashes. Any persistent rashes or rashes that are refractory to appropriate treatment may warrant a skin biopsy to rule out cancer.
