Staph on Lips: Causes, Symptoms, and Treatment - Verywell Health

Staphylococcus aureus (S. aureus or staph) is a bacterium that lives on the skin. Staph causes millions of skin and soft tissue infections yearly, including lip infections.

The bacteria enter through a cut or wound around the lips and infect the surrounding tissue. Staph can also travel to other organs via the bloodstream. Although most staph infections are treatable, they can be deadly if not handled quickly.

This article will discuss the symptoms, causes, diagnosis, and treatment for staph infections on the lip.

Staph Infection Symptoms

Staph infections can cause mild to severe side effects. Common symptoms of a lip staph infection include:

  • Redness
  • Swelling
  • Tenderness
  • Warmth
  • Drainage
  • Ulceration
  • Fever/shaking chills

If the staph infection travels to the bladder, it can cause pain, frequency, and urgency of urination. If the bacteria infect the joints or bones, it can cause pain. Coughing and shortness of breath could indicate staph pneumonia.

Tell your healthcare provider immediately if you have a lip staph infection and experience any of the above symptoms, as treatment needs to be started quickly.

What Does a Staph Infection on the Lips Look Like?

A staph infection of the lip can start as a small, red bump. Once the body's immune system recognizes the bacteria as foreign, it sends white blood cells to the area to fight the infection. This immune response causes the bump to become inflamed, tender, and filled with pus. Eventually, the bump may rupture, causing the fluid to drain out and the area to crust over. If left untreated, staph may travel to the bloodstream resulting in a blood infection called bacteremia.

Staph Infection Causes

Any opening in the skin increases the susceptibility to a staph infection. As the bacteria invade the tissue, it colonizes and spreads. Common skin conditions that can result in a lip staph infection include:

Other risk factors for staph infections include being African American, having a weakened immune system, being diabetic, and having previous staph infections.

How Common Are Staph Infections?

S. aureus is found in approximately 30% of the human population and is responsible for 14 million outpatient visits yearly.

Diagnosis

Staph infections are diagnosed based on what body system could be infected. The following are ways to diagnose a staph infection:

A wound culture is likely to be performed for a lip staph infection. Your healthcare provider will take a special swab and collect drainage or tissue from the site of infection. The swab is then sent to a laboratory for testing. It can take up to 72 hours for a result.

Complications of Staph on the Lips

Most staph infections are typically easy to treat with a straightforward recovery. However, nearly 20,000 people died from staph bacteremia in 2017.

Complications of a lip staph infection occur when the bacteria infects the blood and other organs. Here are complications that can occur with a lip staph infection:

  • Cellulitis or abscess of the lip
  • Joint infection
  • Osteomyelitis (bone infection)
  • Pneumonia (lung infection)
  • Cardiovascular infection (endocarditis)
  • Pyelonephritis (kidney infection)
  • Bacteremia (blood infection)

Additionally, staph can become resistant to antibiotics—this is called methicillin-resistant Staphylococcus aureus (MRSA).

Treatment

Treatment depends on the severity of the infection. Uncomplicated staph infections may improve over time by simply keeping the area clean and dry. There are also medicated creams and gels that can be applied topically to the infected area. More complicated infections, however, may require oral or intravenous antibiotics in addition to surgical debridement (removal of tissue) of the wound.

How Staph Spreads

Staph is contagious and can spread from person to person by coming into contact with a wound. In addition, using an infected person's washcloth, razor, or other personal items can spread the bacteria.

Prevention

Despite best efforts, staph infections can recur, especially if it's MRSA. Here are ways to help prevent a lip staph infection:

  • Keep lips moisturized to reduce cracking and skin breakdown
  • Keep fingernails trimmed and clean
  • Regularly wash face and hands
  • Change wash clothes/towels daily
  • Don't share cups, utensils, lip gloss, razors, toothbrushes, or other personal items
  • Disinfect frequently touched surfaces

If you have a MRSA-positive lip staph infection, your healthcare provider may prescribe a topical cream, medicated facial wash, or prophylactic antibiotics.

When to See Your Healthcare Provider

Contact your healthcare provider if you have a lip staph infection that isn't improving or you develop fever, shaking chills, or worsening pain.

Summary

Staph is a bacteria that causes skin and soft tissue infections in millions of people yearly. When staph enters the skin around the lips through a cut or crack, it colonizes and spreads. The body's immune system attacks the bacteria causing inflammation, redness, tenderness, and warmth at the infected site.

A staph infection of the lip may resolve by keeping the area clean and dry. However, more severe cases may require an oral or intravenous antibiotic. You may be able to prevent a lip staph infection by routinely washing your face and hands and not sharing personal hygiene items. Call your healthcare provider immediately if you have signs of a lip staph infection and develop a fever or shaking chills.

A Word From Verywell

Complications from staph infections are more likely to occur in certain populations. For example, if you are over the age of 70 and are a male, your risk for bacteremia (blood infection) increases. Also, people who are HIV+ or are receiving hemodialysis have higher rates of acquiring bacteremia. Additionally, Black people in the United States are twice as likely to develop MRSA than White people.

Make an appointment with your healthcare provider at the first sign of a staph infection—especially if you are part of these at-risk populations—so you start treatment immediately.

Frequently Asked Questions

  • A staph infection often starts as a small, red bump. If untreated, the bump can become inflamed, red, and tender. It can also fill with pus and leak.

  • Uncomplicated staph infections may resolve independently by keeping the area clean and dry. However, if this skin is red and irritated or accompanied by a fever or pus, it's important to see a healthcare provider immediately.

  • Staph can spread through contact with the wound or by using personal items such as razors, toothbrushes, and clothes of those infected with the bacteria.

A Nova Scotia man is thanking a digital watch for saving his life. Travis Chalmers, of Elmsdale, N.S., said he was outside playing road hockey with his son when he suddenly experienced a "warm sensation" in his chest area and a splitting headache. "I just thought it was a flu or cold coming on and my seasonal allergies had been kicking in. I thought it was flu-like symptoms and shrugged it off," he said. But to Chalmers' surprise, an otherwise laidback afternoon eventually took a scary turn when he glanced at his wrist. A notification from his Apple Watch led him to discover he was experiencing a heart attack. "About a half hour later, I'm laying down with my daughter and my heart rate is still beating out of my chest," he continued, adding that he monitored his heart rate on his Apple Watch for the next few hours. The watch indicated that he was experiencing atrial fibrillation, a rapid heart rhythm that can increase the ris...

Like many things, there's another side to the opioid crisis. While the addiction to opioids is a problem that needs to be addressed, people who are using the drugs exclusively as prescribed — and who still truly need it from a medical perspective — have been swept up in what some have seen as government's knee-jerk reaction to the crisis. In having their ability limited to get the drugs they need in order to function, many of these patients are left suffering debilitating pain. Richard Mark VanWormer w...

She'd been coughing for days, but that morning the pain was so bad she was worried that it had turned into pneumonia. She tried to tough it out, but when it was no better by the end of the day, she decided to go to the E.R. It took a few hours, but finally the physician assistant caring for her in the E.R. brought some good news. She didn't have pneumonia; she didn't have a clot in her lungs. This was just muscle strain from coughing. The year before, she was told she had asthma. She was given inhalers to stop the coughing and wheezing, but they didn't seem to do much. So she didn'...
