What is the difference between impetigo and cellulitis?

Impetigo and cellulitis are both skin infections, but they are caused by different bacteria and have different symptoms.

Impetigo

* Caused by bacteria called Staphylococcus aureus or Streptococcus pyogenes

* Usually occurs on the face, arms, or legs

* Starts as small, red bumps that quickly turn into blisters

* Blisters break and form a crust

* Crusts can be yellow, brown, or black

* Impetigo is contagious and can be spread through contact with an infected person or object

Cellulitis

* Caused by bacteria that enter the skin through a break in the skin, such as a cut, scrape, or burn

* Usually occurs on the legs, but can also occur on the arms, face, or trunk

* Starts as a red, swollen, and painful area

* The affected area may be warm to the touch

* Cellulitis is also contagious and can be spread through contact with an infected person or object

Treatment

Impetigo and cellulitis are both treated with antibiotics. Impetigo can usually be treated with topical antibiotics, while cellulitis may require oral antibiotics. In some cases, hospitalization may be necessary.

Prevention

The best way to prevent impetigo and cellulitis is to keep your skin clean and free of cuts and abrasions. If you do get a cut or scrape, be sure to clean it thoroughly and apply a bandage. Avoid contact with people who have impetigo or cellulitis.
