Cellulitis is a common infection of the deep layers of the skin, commonly caused by bacteria called Staphylococcus or Streptococcus.
Normally, skin acts as a barrier to protect our bodies from bacteria. When there is damage to this skin barrier, such as with a cut, eczema, or a bug bite, bacteria can enter through microscopic cracks in the skin and cause cellulitis. Sometimes cellulitis can occur without a clear cause. It is important to seek medical care if you think you have cellulitis, as this condition is easily treated with medicine prescribed by a physician. It may become serious if ignored.
