Most cuts heal quickly. However, if a cut becomes infected, it can lead to serious illness if left untreated.

Skin infections likestrep or methicillin-resistant Staphylococcus aureus(MRSA) can start from the tiniest cuts. Even a little cut that doesn’t need stitches can cause significant problems if it becomes infected and goes untreated. So, how can you tell if a cut is infected?

This article will help you understand when to seek help from a medical provider, what an infected cut looks like, and how to treat cuts at home.

signs of an infected cut

Certain cuts require contacting a healthcare provider for advice instead of attempting home treatment. These cuts have a higher risk of infection. In most instances, washing and covering the cut first is appropriate.

However, after the initial care, cuts where you should contact a healthcare provider include:

If you were bitten, your healthcare provider will want to ensure the animal that bit you was fully vaccinated. If another person bit you, there is also the risk of infectious disease that your healthcare provider may want to monitor or treat prophylactically.

Additionally, if your cut is from a rusty or dirty surface, your healthcare provider may want to ensure you are up to date on your vaccines, such astetanus. You may need a booster.

Specific individuals may be at a higher risk of developing an infection. If you have diabetes, are immunocompromised, or have another health condition that impacts your ability to fight infection, contact your healthcare provider for advice.

Some redness and swelling are part of the healing process and are expected. However, cuts that are not infected should begin healing quickly. There are several signs a cut is infected. Look for the following symptoms:

If your cut or scrape is due to an animal bite or you cut yourself on a dirty or rusty object, contact your healthcare provider for advice. These types of injuries are more likely to become infected. Also, your provider will want to ensure that if an animal bites you, they are up to date on their vaccines, such asrabies.

If you scraped yourself on a rusty or dirty object, it is important to ensure your vaccines, such as tetanus, are up to date. Your provider can provide information on whether or not additional care, such as antibiotics or vaccines, is needed.

How to Treat an Infected Cut at Home

Minor infected cuts may be treated at home. However, if you have any of the following risk factors that make you more likely to experience complications from an infected cut, contact your healthcare provider prior to attempting home treatment. Conditions that can make you more susceptible to severe infection include:

If you are otherwise healthy, you can try the following:

Some initial redness and swelling are expected. However, if symptoms persist or worsen over several days despite home treatment, you may need to contact your healthcare provider.

If your cut is larger or deeper or your injury occurred on a dirty or rough surface, consider contacting your healthcare provider instead of attempting home treatment.

Will an Infected Cut Heal on Its Own?

Whether an infected cut can heal on its own depends on your overall health, the severity of the cut, and the surface that caused the cut. For example, a shallow cut made with a generally clean kitchen knife while cutting fruits or vegetables is less likely to become infected than a scrape from a rusty, old piece of metal.

If aninfected cutis left alone without treatment, complications may develop.

In most cases, healthcare providers willprescribe antibioticsto fight the infection. Untreated, infected wounds can become serious. They may develop into cellulitis or an abscess. Rarely can they lead to sepsis or necrotizing fasciitis.

Cellulitis

Cellulitisis an infection deeper in the skin. If you develop cellulitis, you will need antibiotics. If not treated, cellulitis can lead to more severe infections if the bacteria infect your bloodstream, heart, bones, or joints.

Abscesses

Abscessesare pockets of pus. Your healthcare provider may need to drain the abscess to help it heal. Depending on how well they can drain and clean the wound, they may or may not prescribe antibiotics. If an abscess is left untreated, it can lead to a systemic infection.

Systemic Infection

If an infected cut leads to a systemic (full-body) infection, you may feel as though you have a bad case of the flu. Symptoms may include:

Seek medical care if you believe you have developed a systemic infection from a cut.Sepsisis an extreme reaction to an infection and requires immediate care.

Necrotizing Fasciitis

Another rare complication that also requires immediate care isnecrotizing fasciitis. This complication can lead to limb loss and significant scarring from removing the infected tissue. Early symptoms of necrotizing fasciitis include severe pain beyond the initial injury, a fever, and redness and swelling that spread quickly.

Treatment will depend on the extent of the infection. A healthcare provider may prescribe oral, IV, or injected antibiotics depending on the severity of the infection.

They may or may not collect cultures to determine which organism is causing the infection. Some antibiotics are considered broad-spectrum and work against several bacteria, while some are more specific.

If your provider prescribes oral antibiotics, follow the instructions on the label and take all of the medication as prescribed. Even if yourinfection improvesafter a couple of days, it is essential to complete the entire prescription. Not taking all of the medication as prescribed can lead toantibiotic resistanceand a more challenging infection to treat.

In the case of an abscess, a healthcare provider will likely drain and cover it. They may pack it, too.

Additional treatment may be necessary if you have a condition that makes you more susceptible to a worse infection, such as diabetes.

To avoid an infected cut, it’s important to wash the initial injury and keep cuts clean as they heal. Most of the time, soap and water are all you need.Antibiotic ointments, such as Polysporin, usually aren’t necessary.

Covering the injury with an adhesive bandage can also help keep the injury clean. Ensure you change the bandage daily or whenever it gets wet or dirty.

Summary

In most cases, cuts and scrapes heal on their own with basic home care such as cleaning and bandages. However, if your cut develops signs of an infection, especially if you have an underlying medical condition, seek the advice of your healthcare provider.
