Staph Infections: Causes and Treatments
Staph infections are common bacterial infections caused by Staphylococcus bacteria. These bacteria can be found on the skin or in the nose of many healthy individuals without causing any problems. However, when they enter the body through a cut or wound, they can cause infections ranging from minor skin problems to severe diseases.

Get A Second OpinionWhat is a Staph Infection?
Staphylococcus bacteria, commonly known as staph, are a group of bacteria that can cause a wide variety of infections. These bacteria are usually harmless on the skin but can become problematic if they enter the body.
Staph infections can manifest in several ways, including:
- Boils
- Impetigo
- Cellulitis
- Food poisoning
- Toxic shock syndrome
- Septicemia (blood poisoning)
Causes of Staph Infections
Staph bacteria can be spread through:
- Direct contact with an infected wound
- Sharing personal items like towels or razors
- Contact with surfaces contaminated with staph bacteria
The bacteria can enter the body through:
- Cuts and scrapes
- Insect bites
- Surgical wounds
Certain factors can increase the risk of developing a staph infection, such as:
- Having a weakened immune system
- Living in crowded or unsanitary conditions
- Using intravenous drugs
- Having chronic conditions like diabetes or cancer
Symptoms of Staph Infections
The symptoms of a staph infection depend on where the infection is located and can vary widely.
Skin Infections
Skin infections are the most common type of staph infection. Symptoms can include:
- Red, swollen, and painful areas on the skin
- Pus-filled blisters or boils
- Warmth around the infected area
- Fever
Food Poisoning
When staph bacteria contaminate food, they can cause food poisoning. Symptoms include:
- Nausea and vomiting
- Diarrhea
- Dehydration
- Low blood pressure
Toxic Shock Syndrome
Toxic shock syndrome (TSS) is a rare but life-threatening condition caused by toxins produced by staph bacteria. Symptoms include:
- Sudden high fever
- Low blood pressure
- Rash resembling sunburn
- Confusion
- Muscle aches
Septicemia
Septicemia, or blood poisoning, occurs when staph bacteria enter the bloodstream. Symptoms include:
- Fever and chills
- Low blood pressure
- Rapid heartbeat
- Shortness of breath
- Confusion
Diagnosing Staph Infections
To diagnose a staph infection, a healthcare provider will:
- Review your medical history and symptoms.
- Conduct a physical examination, looking for signs of infection.
- Collect a sample from the affected area (e.g., skin, blood, or urine) for laboratory testing.
Blood Test for Staph Infection
A blood test can help determine if staph bacteria are present in the bloodstream. This test is crucial for diagnosing more severe infections like septicemia.
Treatment Options for Staph Infections
Treatment for a staph infection depends on the type and severity of the infection.
Antibiotics
Antibiotics are the most common treatment for staph infections. Common antibiotics used include:
- Penicillin
- Methicillin
- Vancomycin
- Clindamycin
It's essential to take the full course of antibiotics as prescribed, even if symptoms improve, to ensure that the infection is entirely eradicated.
Drainage
For skin infections like boils or abscesses, a healthcare provider may need to drain the infected area to remove pus and reduce swelling. This procedure is typically done in a sterile environment to prevent further infection.
Supportive Care
For more severe infections, hospitalization may be necessary. Supportive care can include:
- Intravenous (IV) fluids to maintain hydration and blood pressure
- Medications to manage pain and fever
- Oxygen therapy for breathing difficulties
Preventing Staph Infections
Preventing staph infections involves good hygiene practices and taking precautions to avoid spreading bacteria.
Personal Hygiene
- Wash your hands frequently with soap and water.
- Keep cuts and wounds clean and covered until they heal.
- Avoid sharing personal items like towels, razors, or clothing.
- Shower promptly after sports or activities that cause sweating.
Environmental Cleanliness
- Clean and disinfect frequently-touched surfaces regularly.
- Launder bedding and towels in hot water.
- Use antiseptic solutions to clean gym equipment and other shared items.
