Chicken Pox

• Chicken pox is a viral rash starting in one part of the body with a few red spots. On the second day more bumps appear as the first ones turn into blisters. New bumps emerge on the third day with second-day bumps starting to blister. By the third day all blisters begin crusting over. A child is no longer contagious after all the bumps have disappeared and the fever is gone. Although chicken pox isn't considered a severe disease, it is highly contagious, causing itching and discomfort.
  
  

Hives

• Hives, which are welts, suddenly appear, spreading quickly over a child's body. They mostly affect the trunk, although they can also be on arms, legs and the face. An attack of hives can last for only 10 or 15 minutes or as long as hours, according to Ask Dr. Sears.com. Welts can be single, grouped together or over-lapping. Normally hives itch, although not always. Hives are caused by allergies to foods and medications, detergents, soaps, grasses or clothing. The condition is usually treated with Benadryl.
  
  

Eczema

• Eczema is due to a genetic tendency to irritated dry skin or skin allergies to various foods and irritants. The rash is dry, red and itchy and can appear on knees, elbows, the face, trunk, hands and feet. A child can have only one patch or many. It can be either a temporary or chronic condition that lasts for years. Usually, eczema is treated with over-the-counter hydrocortisone cream.
  
  

Roseola

• Roseola typically starts with a high fever. About the fourth day the fever breaks, followed by a bright red rash beginning on the neck and upper back which spreads down to the trunk, arms and legs. Because kids usually develop small red bumps on their hands, soles of their feet and even the back of their throats, it's called "hands, foot-and-mouth disease." Roseola goes away on its own without any particular treatment.
  
  

Impetigo

• Impetigo, a bacterial skin infection, can occur almost anywhere on a child's body. However, the common area is the nose and mouth. This rash appears as raised red bumps that crust over into patches of honey-colored scabs. Although it's usually not painful, it causes itching. It's treated using an antibiotic ointment.
  
  

Life Threatening Disorders Displaying Skin Rashes

• Although rare, there are five extremely dangerous disorders that show skin rashes as a prime symptom. According to Omniglot.com, these life-threatening rashes include toxic shock syndrome, toxic epidermal necrolysis, pemphigus vulgaris, Stevens-Johnson syndrome and staphylococcal scalded skin syndrome. These are rashes of the mucus membranes that do not blister. It's important that parents seek immediate medical care for their children who have any of these non-blistering rashes, as they can be fatal.
