==Risk factors==
The [[elderly]] and those with [[Immunodeficiency|weakened immune systems]] are especially vulnerable to contracting cellulitis. [[diabetes mellitus|Diabetics]] are more susceptible to cellulitis than the general population because of impairment of the [[immune system]]; they are especially prone to cellulitis in the feet because their disease causes impairment of blood circulation in their legs leading to their having [[Diabetic foot|foot ulcers]] that commonly become infected. Cellulitis is also a common complication of [[obesity]].
[[Immunosuppressive drug]]s, [[HIV]], and other illnesses or infections that weaken the immune system are also factors that make infection more likely. In addition, [[chickenpox]] and [[shingles]] often result in blisters which break, providing a gap in the skin through which bacteria can enter. [[Lymphedema]], which causes swelling on the arms and/or legs, can also put an individual at risk.
Diseases that affect blood circulation in the legs and feet, such as chronic venous insufficiency and [[varicose vein]]s, are also risk factors for cellulitis.
Cellulitis is also extremely prevalent amongst dense populations sharing hygiene facilities and common living quarters. Military installations which require communal showers provide such an environment, as it is prevalent among many recruits going through boot camp.

Diagnosis

Cellulitis is most often a clinical diagnosis, and local cultures do not always identify the causative organism. Blood cultures usually are positive only if the patient develops generalised sepsis. Conditions that may resemble cellulitis include deep vein thrombosis, which can be diagnosed with a compression leg ultrasound, and stasis dermatitis, which is inflammation of the skin from poor blood flow.

Incubation

Cellulitis can develop in as little as twenty-four hours or can take days to develop.

Duration

In many cases, cellulitis takes less than a week to disappear with antibiotic therapy. However, it can take months to resolve completely in more serious cases, and can result in severe debility or even death if untreated. If it is not properly cured it may appear to improve but can resurface again even after months and years.

Treatment

Antibiotics - typically a combination of intravenous and oral antibiotics are administered. Bed rest and elevation of affected limbs is also recommended. Drink plenty of fluids as well - at least 8 glasses of water a day.

Prevention

Good hygiene and good wound care lower the risk of cellulitis. Any wounds should be cleaned and dressed appropriately. Changing bandages daily or when they become wet or dirty will reduce the risk of contracting cellulitis. Medical advice should be sought for any wounds which are deep, dirty or if there is concern about retained foreign bodies.

Cellulitis in horses

Horses may acquire cellulitis, usually secondary to wound (which can be extremely small and superficial) or to a deep-tissue infection, such as an abscess or infected bone, tendon sheath, or joint. Cellulitis from a superficial wound will usually create less lameness (grade 1-2 out of 5) than that caused by septic arthritis (grade 4-5 lameness). The horse will exhibit inflammatory edema, producing a hot, painful swelling. this swelling differs from stocking up in that the horse will not display symmetrical swelling in 2 or four legs, but only in one leg.

This swelling begins near the source of infection, but will eventually continue downward the leg. In some cases, the swelling will also travel upward. Treatment includes cleaning the wound and caring for it properly, the administration of NSAIDs, such as phenylbutazone, cold hosing, applying a sweat wrap or a poultice, and mild exercise. Veterinarians may also perscribe antibiotics. Recovery is usually quick and the prognosis is very good if the cellulitis is secondary to skin infection.
