Rash with signs of infection in children

Generally, a skin infection is more likely to develop after an injury, such as a cut or scrape. However, a very minor skin injury may go unnoticed and may become infected. In cases like this, what looks like a rash may actually be a skin infection.

Any rash breaks down the skin barrier and makes it more susceptible to infection, so rashes may also become infected. Signs of infection may include:

• Increased pain, swelling, redness, or warmth around the affected area.
• Red streaks extending from the affected area.
• Drainage of pus from the area.
• Swollen lymph nodes in the neck, armpit, or groin.
• Fever of 100.4° (38°) or higher, or chills with no other known cause.

Chickenpox sores usually heal with the use of home treatment. It is important to watch for signs of infection, because occasionally a chickenpox sore will become infected and require a visit to a health professional.

Minor impetigo sores may heal with the use of home treatment. Occasionally the impetigo will spread and require a visit to a health professional.

Prompt treatment of a skin infection can prevent the infection from spreading to surrounding tissues or throughout the body.
