A bacterial infection that often shows up as a rash, cellulitis can spread rapidly.
Cellulitis is a skin infection caused by staphylococcus or streptococcus bacteria. It is not contagious.
Cellulitis appears as a red, swollen skin rash (usually on the lower legs or arms) that feels tender and hot. It can spread rapidly over the course of 24 hours.
In most cases, oral antibiotics effectively treat the infection within 10 to 14 days.
