A rash is a reaction of the skin. It can be caused by many things, such as a drug reaction, an infection, or an allergic reaction. The skin can only react to injury in a few ways, and many different agents can cause rashes that look the same. Often, the symptoms in addition to the rash help make the diagnosis, such as a history of tick bites, exposure to other ill children or adults, recent antibiotic use, environmental exposures, or prior immunizations.
Most rashes caused by viruses do not harm your child and go away over time without any treatment. However, some childhood rashes have serious or even life-threatening causes. As a parent, you should be familiar with these rashes. Many rashes can look the same, making it difficult to know the exact diagnosis. Whenever you have a concern, see your doctor immediately.
