Which are the causes of Staphylococcal Scalded Skin Syndrome?

Staphylococcal Scalded Skin Syndrome (SSSS) is caused by an infection of certain strains of Staphylococcus aureus bacteria that produce specific toxins called exfoliative toxins (ETA and ETB). These toxins enter the bloodstream and travel to the skin, where they break down the connections between skin cells, causing the characteristic blistering and peeling of the top layer of the epidermis.

What triggers Staphylococcal Scalded Skin Syndrome?

The primary cause of Staphylococcal Scalded Skin Syndrome is the release of exfoliative toxins by Staphylococcus aureus. Unlike a direct skin infection, the bacteria often colonize a site like the nose, throat, or umbilical cord, while the damage manifests on the skin surface due to the toxins circulating in the blood. Because the toxins are systemic, they can cause widespread skin peeling even in areas where the bacteria are not physically present.

Is Staphylococcal Scalded Skin Syndrome hereditary?

Staphylococcal Scalded Skin Syndrome is not a genetic or hereditary condition. It is an acute infectious disease. There is no underlying genetic mutation or chromosomal abnormality that causes a person to develop this specific syndrome. However, an individual's immune system maturity and kidney function play a significant role in their susceptibility to Staphylococcal Scalded Skin Syndrome.

Who is at risk for developing Staphylococcal Scalded Skin Syndrome?

While anyone can be affected, Staphylococcal Scalded Skin Syndrome is most commonly seen in infants and young children under the age of 5. This is because their immune systems are still developing and their kidneys are less efficient at filtering the toxins out of the bloodstream. Risk factors include:

• Age under 5 years old (highest prevalence).


• Immune system deficiencies that prevent the body from neutralizing toxins.


• Chronic kidney disease, which reduces the rate at which toxins are cleared from the body.


• Close contact with carriers of the toxin-producing Staphylococcus aureus bacteria.

What is the current state of research?

Medical researchers continue to study why certain strains of bacteria evolve to produce these potent exfoliative toxins. Current research focuses on how the toxin molecules (serine proteases) specifically target the protein desmoglein-1, which acts like "glue" holding skin cells together. Understanding this mechanism helps clinicians develop faster diagnostic tests and more targeted antibiotic treatments for Staphylococcal Scalded Skin Syndrome.

Next steps

• Seek immediate medical attention if you or a child experiences widespread, painful skin redness or blistering.


• Consult an infectious disease specialist or a dermatologist for an accurate diagnosis.


• Connect with the 4 members of the DiseaseMaps community who have experience with Staphylococcal Scalded Skin Syndrome.


• Ensure that skin wounds are kept clean and that hygiene practices are followed to prevent the spread of Staphylococcus aureus.
