Toxic shock syndrome
Toxic shock syndrome (TSS) is a condition caused by bacterial toxins. Symptoms may include fever, rash, skin peeling, and low blood pressure. There may also be symptoms related to the specific underlying infection such as mastitis, osteomyelitis, necrotising fasciitis, or pneumonia.

TSS is typically caused by bacteria of the Streptococcus pyogenes or Staphylococcus aureus type, though others may also be involved. Streptococcal toxic shock syndrome is sometimes referred to as toxic-shock-like syndrome (TSLS). The underlying mechanism involves the production of superantigens during an invasive streptococcus infection or a localized staphylococcus infection. Risk factors for the staphylococcal type include the use of very absorbent tampons, skin lesions in young children characterized by fever, low blood pressure, rash, vomiting and/or diarrhea, and multiorgan failure. Diagnosis is typically based on symptoms.
Treatment includes intravenous fluids, antibiotics, incision and drainage of any abscesses, and possibly intravenous immunoglobulin. The need for rapid removal of infected tissue via surgery in those with a streptococcal cause, while commonly recommended, is poorly supported by the evidence. Some recommend delaying surgical debridement. The overall risk of death is about 50% in streptococcal disease, and 5% in staphylococcal disease. Death may occur within 2 days.
In the United States, streptococcal TSS occurs in about 3 per 100,000 per year, and staphylococcal TSS in about 0.5 per 100,000 per year. The condition is more common in the developing world. It was first described in 1927. Due to the association with very absorbent tampons, these products were removed from sale.
