Celluliis is an infection of the skin, caused by bacteria. Very
often, the face is affected. The disease should not be confused
with cellulite. Cellulitis is caused by bacteria, usually
staphylococcus or streptococcus, which can get through a break
in the skin. These breaks can be caused by a wound, cracks in
the skin, insect bites, or problems with the bodies immune
system. The infection causes the skin to become red, hot and
painful. It can also cause a fever. Treatment is usually by
taking antibiotic drugs. - "Cellulitis - PubMed Health".
