Cellulitis is a spreading infection of the skin that usually begins as a small area of tenderness, contusion, and redness on the skin. As this red area begins to spread, the person may develop a fever, sometimes with chills and sweats, and swollen lymph nodes "swollen glands" near the area of infected skin .Cellulitis is a common infection of the skin and the soft tissues beneath the skin. It occurs when bacteria invade broken or normal skin and start to spread just under the skin or in the skin itself. This results in infection and inflammation. Inflammation is a process in which the body reacts to the bacteria. Inflammation may cause swelling, redness, pain, or warmth.

Cellulitis is obtained by different types of bacteria. For example; if cellulitis develops due to a common household cut, the bacteria responsible is usually either Streptococcus pyogenes or Staphylococcus aureus. If cellulitis develops due to a cat bite, the culprit is usually Pasteurella multocida. The most common infecting organisms are beta-haemolytic Streptococcus pyogenes and Staphylococcus aureus. Less common bacteria include Pseudomonas aeruginosa, particularly following a puncture wound involving the foot or hand, and Haemophilus influenzae in children with facial cellulitis. There are many other ways in which bacteria can get through the skin, such as dog bites or through surgical wounds.

The absorption of Cellulitis treatment is to decrease the severity of the infection, speed up recovery, relieve pain and other symptoms, heal the skin, and prevent the infection from coming back. Antibiotics are usually used to treat cellulitis. If the infection is limited to a small area, has not transmit to the bloodstream or lymph system, and you don't have any other medical problems, antibiotics you take by mouth are effective. If the infection is more widespread, or if you're having a slow recovery on oral antibiotics, antibiotics may be used intravenously or by injection.

For cellulitis of the leg or arm, treatment also includes adorning the limb to reduce swelling and applying a sterile, saline-soaked dressing to aid healing and reduce pain.Treatment for children depends on their age and which part of the body is infected. An antibiotic is usually given intravenously. Facial cellulitis in young children requires immediate treatment and responds well to antibiotics.Treatment sometimes requires a stay in the hospital. This is common if antibiotics must be given intravenously, but it is also considered if you have signs of difficulties such as a high fever, or if it will be difficult for you to have follow-up care with a health professional.
