Cellulitis is a common bacterial infection that affects the deeper layers of the skin. It can cause redness, swelling, warmth, tenderness, and pain in the affected area. Although cellulitis can become serious if left untreated, it is usually not contagious and generally cannot be spread from one person to another.
Cellulitis typically develops when bacteria enter the body through a break in the skin, such as a cut, insect bite, puncture wound, or area of cracked skin. In some cases, the break may be so small that it is difficult to notice.
Understanding what causes cellulitis, how it develops, and when it requires medical attention can help you recognize symptoms early and seek appropriate care. If symptoms are severe, spreading quickly, or accompanied by fever or other concerning signs, our Beaumont ER can provide prompt emergency evaluation.
What Is Cellulitis?
Cellulitis is a bacterial infection involving the deeper layers of the skin and the tissue underneath it. It can develop anywhere on the body, although the lower legs and feet are common locations.
The infection usually occurs when bacteria enter through damaged or broken skin and multiply beneath the skin’s surface. This can cause inflammation in the affected area, leading to redness, swelling, warmth, tenderness, and pain.
Cellulitis can affect people of any age. While many cases can be treated successfully with antibiotics, untreated cellulitis may spread to deeper tissues or the bloodstream and cause more serious complications.
H2: When Is Cellulitis Contagious?
Cellulitis itself is not considered a contagious infection, so there is not a specific stage when a person with cellulitis becomes contagious.
The concern is instead how the bacteria entered the skin and whether there is another type of infection present. A person with cellulitis may have bacteria on their skin or around a wound, but simply coming into contact with someone who has cellulitis does not normally cause another person to develop cellulitis.
If an affected area has an open wound, drainage, or another type of skin infection, it is still important to practice good hygiene. Keep wounds clean and covered when appropriate, wash your hands regularly, and avoid sharing personal items that may come into contact with an infected wound.
If you are unsure whether a skin infection is cellulitis or another condition that may spread through contact, medical evaluation can help determine the appropriate next steps.
How Cellulitis Develops
Cellulitis usually occurs when bacteria get through a break in the skin. This can happen after:
- Cuts or scrapes.
- Insect bites.
- Puncture wounds.
- Surgical wounds.
- Burns or other skin injuries.
- Cracked or dry skin.
- Skin conditions such as eczema or athlete’s foot.
Sometimes the opening in the skin is so small that you may not notice it.
Symptoms of Cellulitis
Cellulitis can cause noticeable changes in the affected skin. Common symptoms include:
- Redness: The infected area may appear red or discolored and can gradually become larger.
- Swelling: The skin may become swollen, tight, or puffy around the affected area.
- Warmth: Infected skin often feels warmer than the surrounding skin.
- Pain and tenderness: The area may hurt or feel tender when touched.
- Blisters: Some people may develop blisters over the affected skin.
- Fever or chills: A more widespread infection may cause fever, chills, or flu-like symptoms.
Symptoms can vary depending on where the infection develops and how extensive it becomes. If redness spreads quickly or you develop fever or chills, seek medical attention promptly.Risk Factors for Cellulitis
Certain conditions and situations can increase the likelihood of developing cellulitis.
Skin Injuries
Cuts, scrapes, puncture wounds, insect bites, burns, and other injuries can create an opening through which bacteria can enter the deeper layers of the skin. Even a small break may provide an entry point for infection.
Chronic Skin Conditions
Conditions such as eczema and athlete’s foot can cause dryness, cracking, or other damage to the skin. These changes can make it easier for bacteria to enter.
Swelling and Lymphedema
Long-term swelling in the arms or legs can increase the risk of cellulitis. Lymphedema, which causes fluid to build up under the skin, is one condition associated with an increased risk.
Weakened Immune System
A weakened immune system may make it more difficult for the body to fight bacterial infections. Certain medical conditions and treatments can affect immune function.
Diabetes and Other Health Conditions
Diabetes and other health conditions can increase the risk of skin infections, particularly when they affect circulation, wound healing, or the body’s ability to fight infection.
Treatment for Cellulitis
Cellulitis is generally treated with antibiotics. Depending on the severity of the infection, treatment may involve oral antibiotics or intravenous antibiotics for more serious cases. If you are looking for the closest emergency room near me, prompt evaluation can help determine the appropriate treatment when symptoms are severe.
Healthcare providers typically diagnose cellulitis by examining the affected skin. Most cases do not require extensive testing, although additional evaluation may be needed when the infection is severe or complications are suspected.
It is important to follow the treatment plan provided by a healthcare professional. If symptoms do not begin improving after treatment or become worse, additional medical evaluation may be necessary.
Preventing Cellulitis
You can take steps to reduce your risk of developing cellulitis, especially if you have previously had the infection or have other risk factors.
- Keep cuts, scrapes, and other wounds clean.
- Protect your skin from unnecessary cuts and injuries.
- Keep your skin moisturized to reduce cracking and dryness.
- Treat conditions such as athlete’s foot promptly.
- Follow appropriate care instructions for surgical wounds.
- Pay attention to swelling, redness, or other changes around an injury.
Taking care of breaks in the skin can help reduce opportunities for bacteria to enter deeper tissues.
When To Go To The ER
Cellulitis should be evaluated promptly when symptoms are significant, worsening, or spreading. Seek emergency medical care if the affected area is spreading quickly or you develop symptoms that may indicate a serious infection.
Emergency warning signs can include:
- Very high fever or severe chills.
- Rapid heartbeat or breathing.
- Dizziness or fainting.
- Confusion or disorientation.
- Purple patches or significant skin discoloration.
- Cold, clammy, or unusually pale skin.
- Loss of consciousness or unresponsiveness.
These symptoms can indicate serious complications and require immediate medical attention.

Frequently Asked Questions
Is cellulitis contagious through touch?
No. Cellulitis is generally not spread through ordinary physical contact. The infection usually develops when bacteria enter through a break in the skin and infect deeper tissues.
Can I get cellulitis from someone who has it?
You generally cannot catch cellulitis from another person. Having contact with someone who has cellulitis does not normally cause you to develop the infection.
Can cellulitis spread to other parts of the body?
Yes. If cellulitis is not treated promptly, the infection can spread to deeper tissues or other parts of the body, including the bloodstream, muscles, or bones.
How long does cellulitis take to heal?
Recovery varies depending on the severity of the infection and the individual’s response to treatment. NHS guidance notes that many people make a full recovery within 7 to 10 days after appropriate treatment, although more serious infections may require longer care.
Can cellulitis come back?
Yes. Having cellulitis previously can increase the risk of developing it again. Managing underlying risk factors and caring for the skin can help reduce the chance of recurrence.
Can cellulitis be treated at home?
Cellulitis generally requires medical evaluation because bacterial cellulitis is commonly treated with antibiotics. If symptoms are worsening, spreading, or accompanied by fever or other concerning symptoms, seek medical care promptly.
