OVERVIEW
What is Cellulitis?
Cellulitis is a bacterial skin infection that affects the deeper layers of the skin and the underlying tissue. It is typically caused by a type of bacteria such as Streptococcus or Staphylococcus, and it is characterized by redness, swelling, warmth, and pain in the affected area. Cellulitis can occur on any part of the body, but it is most commonly found on the legs, arms, and face. If left untreated, cellulitis can spread to other parts of the body and cause serious complications, so it is important to seek medical treatment as soon as possible if you suspect you may have cellulitis.
CAUSES AND RISK FACTORS
The most common cause of cellulitis is a bacterial infection. The bacteria typically enter the skin through a break, such as a cut, sore, or insect bite. Once inside the skin, the bacteria begin to multiply, causing inflammation and infection.
Some of the most common risk factors for cellulitis include:
- Having a weak immune system
- Having a history of cellulitis or other skin infections
- Having a skin condition that causes breaks in the skin, such as eczema or psoriasis
- Having poor circulation, particularly in the legs
- Having a recent injury or surgery
- Having diabetes or other conditions that affect the circulation
- Having a history of lymphatic obstruction
- Having a history of intravenous drug use.
Additionally, older adults and people who have recently had surgery or who have a weakened immune system are at a higher risk of developing cellulitis.
SIGNS AND SYMPTOMS
The signs and symptoms of cellulitis can vary depending on the severity of the infection and the area of the body that is affected. Some of the most common symptoms include:
- Redness and warmth in the affected area
- Swelling and tenderness of the skin
- Pain or a burning sensation in the affected area
- A fever or chills
- Fatigue and muscle aches
- A red, raised area of skin that is warm to the touch
- Blisters or ulcers on the skin
- Swelling of the lymph nodes in the affected area
- Red streaking or spreading of the infection

DIAGNOSIS
Diagnosis of cellulitis typically involves a combination of physical examination and lab tests. The following are the common ways to diagnose cellulitis:
- Physical examination: A healthcare provider will examine the affected area of the skin, looking for signs of redness, swelling, warmth, and tenderness. They may also check for signs of spreading, such as red streaks or blisters. The healthcare provider may also check the person's temperature, pulse, and breathing to assess the extent of the infection.
- Lab tests: The healthcare provider may also order lab tests to confirm the diagnosis and identify the specific type of bacteria causing the infection. This may include a blood culture or a wound culture. Blood tests may also be done to check the person's white blood cell count, which can be elevated in cases of infection.
- Imaging studies: In some cases, the healthcare provider may order imaging studies such as an X-ray, CT scan, or Ultrasound, to check for any underlying conditions that may have caused the cellulitis or to check if the cellulitis has spread to deeper structures such as bones or lymph nodes.
In summary, cellulitis is diagnosed by the combination of the healthcare provider's examination of the affected area, lab tests, and in some cases, imaging studies.
MANAGEMENT AND TREATMENT
The main goal of treatment for cellulitis is to eliminate the bacterial infection and prevent the spread of the infection to other parts of the body. The following are common management and treatment options for cellulitis:
- Antibiotics: Cellulitis is typically treated with antibiotics to kill the bacteria causing the infection. The type of antibiotic and the duration of treatment will depend on the severity of the infection and the type of bacteria causing the infection. In most cases, antibiotics are given intravenously (through a vein) in the hospital for the first few days, and then the patient may continue to take oral antibiotics at home for a week or two.
- Pain relief: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help to relieve pain and reduce inflammation.
- Elevation: Elevating the affected limb, especially if it's on the legs, can help to reduce swelling and improve circulation.
- Compression: Compression bandages may be applied to the affected area to help reduce swelling and prevent the spread of the infection.
- Wound care: If cellulitis is caused by a wound, it is important to keep the wound clean and covered to prevent further infection.
- Hospitalization: If the cellulitis is severe, or if there is a high risk of complications, the person may need to be hospitalized for treatment.
In summary, the treatment of cellulitis typically involves a combination of antibiotics to eliminate the bacterial infection, pain relief, elevation, compression, wound care, and in some cases, hospitalization. It is important to complete the full course of antibiotics as prescribed, even if symptoms improve, to ensure that all bacteria are eliminated, and prevent recurrences.
COMPLICATIONS
Cellulitis, if not treated promptly and effectively, can lead to serious complications. Some of the most common complications include:- Spread of the infection: Cellulitis can spread to other parts of the body, such as the lymph nodes, bones, or bloodstream. This can lead to more severe infections and potentially life-threatening conditions.
- Septicemia: If the bacteria from the cellulitis infect the bloodstream, it can cause sepsis, which is a serious and potentially life-threatening condition.
- Abscess: An abscess can form if the infection becomes deep and pus accumulates. This can cause severe pain and swelling and may require surgical drainage.
- Lymphedema: Cellulitis can lead to swelling of the lymphatic vessels, which can cause lymphedema. This can lead to chronic swelling and discomfort and may require long-term treatment.
- Recurrent cellulitis: Cellulitis can recur in people who have a history of the condition or who have underlying risk factors.
- Amputation: In severe cases of cellulitis, particularly in individuals with diabetes or peripheral vascular disease, the affected limb may require amputation.
In summary, cellulitis is a serious condition that requires prompt and effective treatment to prevent complications. It is important to seek medical attention if you suspect you may have cellulitis and to follow the treatment plan as prescribed to prevent recurrences and serious complications.
PREVENTION
There are several ways to reduce the risk of developing cellulitis and prevent recurrences, including:
- Proper wound care: Keeping wounds clean and covered can help to prevent bacteria from entering the skin and causing an infection.
- Good hygiene: Regularly washing the skin with soap and water, particularly in areas that are prone to sweating or rubbing, can help to reduce the risk of infection.
- Avoiding exposure to contaminated water: Cellulitis can be caused by bacteria found in contaminated water, so it's important to avoid swimming or wading in water that may be contaminated with bacteria.
- Managing underlying medical conditions: People with diabetes or peripheral vascular disease are at a higher risk of developing cellulitis, so it's important to manage these conditions to reduce the risk of complications.
- Vaccination: Some people may be at a higher risk of cellulitis due to their occupation or lifestyle, and in these cases, a vaccine may be recommended.
- Limiting exposure to risk factors: Some people may be at a higher risk of cellulitis due to exposure to certain risk factors such as insect bites, animal scratches, or exposure to certain chemicals. Limiting exposure to these risk factors can help to reduce the risk of infection.

PROGNOSIS
The prognosis for cellulitis depends on several factors, including the severity of the infection, the person's overall health, and the promptness and effectiveness of treatment. In general, cellulitis can be a serious condition that requires prompt treatment to prevent complications. However, with appropriate treatment, most people make a full recovery.
Cellulitis caused by common bacteria such as streptococcus and staphylococcus usually responds well to antibiotics. It is important to start the treatment as soon as possible to prevent the spread of the infection and to reduce the risk of complications. With proper treatment, most people will see improvement within a few days and complete recovery within 1-2 weeks.
However, if the cellulitis is caused by a rare or antibiotic-resistant bacteria, treatment may be more difficult and recovery may take longer. In rare cases, the infection may not respond to treatment and may lead to severe complications, such as sepsis, amputation, or even death.
Recurrent cellulitis is more common in people with underlying medical conditions such as diabetes, peripheral vascular disease, and immune system disorders. These individuals may require long-term treatment, including regular check-ups and antibiotic prophylaxis to reduce the risk of recurrence.
It is important to seek medical attention if you suspect you may have cellulitis and to follow the treatment plan as prescribed to prevent recurrences and serious complications.
