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°F (38°C) 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.
