Staph Infections are caused by a group  of bacteria called staphylococcui  that can affect  various parts of the body. They are generally found on the skin or in the nose of even healthy people. Most of the time, such bacteria cause no issues or result in relatively minor skin infections.

It can turn serious if the infection spreads deep inside the tissues entering the systemic circulation, joints, lungs, heart, and other organs. Treatment usually involves antibiotics with draining of fluid from the affected area.


Depending on the site of infection, different forms of infection can occur.

  • Boils- is the most common infection, where pus gets formed in a hair follicle or oil gland ,  inducing the infected area to swell and become red. These boils usually happen near the groin and buttock area or inside the armpits.
  • Impetigo- It exhibits rash-like symptoms forming blisters that ooze fluid or pus, -forming a crust around the infected area.
  • Cellulitis– Cellulitis is an infection that spreads to deeper layers of the skin resulting in swelling and redness on the surface of the skin  and may cause oozing of pus .
  • Staphylococcal skin syndrome- The toxins produced during the infection can cause fever and blisters in children and babies with exfoliation of the top layer of skin.
  • Food poisoning– It is the most common infection caused by staphylococcus when we eat  contaminated food. It causes  symptoms like diarrhea, dehydration, vomiting, nausea, etc.
  • Septic arthritis– It causes knees, shoulder joints, fingers, toes to swell with severe pain frequently leading to fever.
  • Toxic shock syndrome- The toxins produced during the infection can cause high-grade fever, rash, vomiting, nausea, mental confusion, aches in the body, diarrhea, abdominal pain. This life-threatening condition is caused by toxins produced by few strains of staph bacteria and are assoacited with certain types of tampons, skin wounds and surgery.
  • Bacteremia- It is the infection of systemic circulation where the bacteria enter the bloodstream causing fever and low blood pressure. It  can also affect other internal organs like the brain, lungs, heart, bones, muscles.


Humans generally carry bacteria on their skin  but do not develop infection instantly. These bacterias are also transferable from person to person, even from surface to person, as these staph bacteria easily survive in dry and extreme temperatures.

Risk factors and complications

Individuals with weaker immune systems and those with diabetes, HIV, kidney failure, respiratory illness, etc are more vulnerable to staph infections . Staph infections can also be caused by invasive devices used during hospitalization example-Dialysis tubing, catheters, feeding tubes. Bacterias can travel along with the tubing and reach the inner organs. Also, consuming insanitary food by a vendor who is a carrier of staph bacteria can cause infection. Complications with a staph infection are that if the bacterias reach the systemic circulation, it can cause life-threatening septic shock .


Staph infection can get treated with antibiotics. Various antibiotics They can be oral or topical. In case of skin infection, your wound gets dressed, and pus is drained.
