Cellulitis is a bacterial infection usually caused by streptococcal or staphylococcal bacteria. The bacteria infect the deeper layers of skin, causing it to become red and swollen on the surface. The signs and symptoms of this painful condition can develop anywhere on the body, though the legs are most commonly affected. Treatment with antibiotics is required to reduce the symptoms of cellulitis and control the spread of infection.
Any infection can cause a fever because microbes, especially bacteria, stimulate the body to release certain substances in the body that promote fever. Infections may also directly affect the area of the brain that controls the body's temperature. Cellulitis can cause body temperatures to rise above 100.4 F (38.0 C) and can also lead to chills, sweating, and shaking. If a fever persists for more than a day or rises higher than 104 degrees, see a doctor immediately.
