Staph infection

Table of Contents

A staph infection is a bacterial infection that can occur anywhere on the body. The most common type of staph infection is a skin infection, which can range from a small abscess to a large, painful boil. Staph infections can also occur in the lungs, urinary tract, and blood. While most staph infections are not serious, some can lead to life-threatening complications, such as pneumonia or meningitis. Treatment for a staph infection usually involves antibiotics. In some cases, surgery may also be necessary.


What are the symptoms of a staph infection?

The symptoms of staph infection can vary depending on the type of infection. However, some common symptoms include:

  • Red, swollen, and painful skin
  • Pus-filled bumps or blisters
  • Fever
  • Chills
  • Fatigue
  • Body aches
  • Muscle aches
  •  low blood pressure

If the infection spreads to the bloodstream, it can cause more severe symptoms, such as:

  • Sepsis
  • Shock
  • Organ failure


What causes a staph infection?

Most staph infections are caused by a type of bacteria called Staphylococcus aureus, but other types of staph bacteria can also cause infections. These bacteria are commonly found on the skin and in the nose, and they can spread easily from person to person. Sometimes, these bacteria can get into the body through a cut or other wound and cause an infection. Staph infections can range from mild to life-threatening and can occur in any part of the body.


What are the risk factors for staph infection?

There are several risk factors that can increase your chance of developing a staph infection, including:

Having a cut or wound. Staph bacteria can enter the body through an open wound, and this is one of the most common ways that people develop a staph infection.


Having a weakened immune system. If your immune system is not functioning properly, you may be more likely to develop a staph infection.

Being in close contact with someone who has a staph infection. If you have close contact with someone who has a staph infection, you may be at risk of developing an infection yourself.

Having a medical condition that puts you at risk. There are some medical conditions that can increase your risk of developing a staph infection, such as diabetes or cancer.

Being in a hospital or nursing home. If you are in a hospital or nursing home, you may be at increased risk of developing a staph infection.

If you have any of these risk factors, it is important to be aware of the signs and symptoms of a staph infection so that you can seek treatment if necessary.


What are the treatments for staph infection?

Most staph infections can be treated with antibiotics. However, some staph infections are resistant to antibiotics and may require treatment with other medications. Treatment will also depend on the severity of the infection. For example, a skin infection may only require topical antibiotics, while a more serious infection may require oral or intravenous antibiotics. Surgery may also be necessary to drain an abscess or remove infected tissue.


What are the complications of a staph infection?

A staph infection can cause a number of serious complications, including:

  • Blood poisoning (sepsis)
  • Pneumonia
  • Endocarditis (infection of the heart valves)
  • Osteomyelitis (bone infection)
  • Toxic shock syndrome
  • Abscesses throughout the body, including in the brain, liver, and kidneys
  • Cellulitis (skin infection)
  • Impetigo (skin infection)
  • Boils
  • Folliculitis (infection of the hair follicles)
  • MRSA infections (a type of antibiotic-resistant staph infection)

If a staph infection goes untreated, it can quickly become life-threatening.


How can you prevent a staph infection?

You can prevent a staph infection by:

  • Keep the affected area clean and covered with a bandage
  • Avoiding close contact with people who are sick
  • Avoid touching or scratching the infected area
  • Wash your hands regularly and thoroughly, especially after touching the infected area
  • Avoid sharing personal items such as towels, razors, and clothing
  • Practice good hygiene habits such as showering regularly and laundering your clothes frequently
  • Disinfect surfaces that may be contaminated with bacteria



A staph infection can be a serious medical condition, and prompt treatment is essential. If you think you may have a staph infection, it's important to see your doctor right away. Early diagnosis and treatment can help prevent the infection from spreading and becoming more serious.
