Cellulitis is a skin infection which is caused by bacteria. It starts as a small infection causing itching sensation and swelling on the layer of the skin. When the bacteria grows and multiply the affected person may get fever with occasional chills. The glands in the area of the affected part become swollen. The infection you get on developing Impetigo is only superficial but in cellulitis it spreads to the internal parts of the skin like dermis and subcutaneous tissues. The bacteria causing this infection are Streptococcus and methicillin. Though bacteria may attack and infect any part of your body most commonly cellulitis occurs in the lower leg portion and on hands. Sometimes it may infect neck and head areas also. In rare cases bacteria may infect the skin layer on the stomach after a surgical procedure. People who are middle aged are more prone to this infection than children and elderly people.
Cellulitis is caused by staphylococcus and streptococcus bacteria types. When the autoimmune system of the body gets reduced after sudden illness, bacteria may attack the skin and cause infection. Streptococcus is a flesh eating bacteria which invades deeper parts of the skin destroying the cells underneath. A Methicillin resistant bacterium (MRSA) is yet another bacterium which causes cellulitis in children. When people are exposed to freshwater for long duration they may get infected by Aeromonas hydrophilia which are bacteria living on sea water. Cuts or wounds or any other skin injury are affected by the bacteria at faster rate when compared to healthy skin layers.
Since the disease is difficult to diagnose the treatment may get postponed in many cases. The inflammation in the skin and swelling may be due to several reasons. Various types of treatment methods are available for curing cellulitis. In case the swelling is the outcome of autoimmune imbalance the doctor prescribes corticosteroid medications to the patient. Most commonly the bacterial infection can be treated with penicillin and other powerful pills. In case the bacteria are resistant to certain antibiotics or if the patient is allergic to penicillin the doctor may give suitable antibiotics to the affected person. If the infection is very severe the patient will have to be admitted in hospital for administering medicines by intravenous method.
The nature and type of medicine for treating cellulitis vary widely depending on the intensity of the illness and age of the affected person.
