What is cellulitis?
Cellulitis is a common skin infection that happens when bacteria spread through the skin to deeper tissues. Most cases are mild and last several days to a couple of weeks. But cellulitis can sometimes progress to a more serious infection, causing severe illness that affects the whole body (sepsis) or other dangerous problems.
Treatment is needed to help control the infection and reduce symptoms.
Some people are at higher risk for cellulitis, such as those who have diabetes, a weakened immune system, or edema. They also tend to get sicker from cellulitis. And they are more likely to get cellulitis again.
What causes cellulitis?
Cellulitis is caused by bacteria, most often strep or staph. You can get infected after any event that causes a break in the skin, such as:
Sometimes cellulitis can occur even if there wasn't an obvious break in the skin.
What are the symptoms?
Cellulitis can occur anywhere on the body. In adults, it often occurs on the legs, face, or arms. In children, it is most common on the face or around the anus.
If you have signs of a skin infection, such as warmth, redness, swelling, or pain, see your doctor. Even minor infections may need to be treated.
How is it diagnosed?
Doctors are often able to diagnose cellulitis based on your symptoms and a physical exam. In most cases, you won't need further testing.
But tests sometimes may be done to find out what's causing your symptoms and to rule out other problems. For example, you may need blood tests, an ultrasound, or an imaging test such as a CT scan or an MRI.
How is it treated?
Cellulitis is treated with antibiotics. If the infection is mild, you may be able to take antibiotic pills at home.
If the infection is severe, you may need to be treated in a hospital so that you can get IV antibiotics directly into your bloodstream, along with any other care you may need.
Be sure to follow your doctor's instructions about medicine and skin care. To help with your recovery and to feel better:
Call your doctor if your symptoms get worse or if they haven't started to improve within 48 hours (2 days) after you start taking antibiotics.
How can you prevent cellulitis?
If you are at risk for cellulitis, you can take steps to help prevent it. If you've had cellulitis before, these steps may help prevent it from coming back.
