An exotoxin-mediated illness caused by bacterial infection, most commonly group A streptococcus or Staphylococcus aureus .
Presenting signs and symptoms can be nonspecific, but the course of the disease is precipitous and toxicity occurs early, resulting in serious life-threatening disease and multiorgan system failure.
Early diagnosis and treatment is essential.
Streptococcal toxic shock syndrome (TSS) can occur with infection at any site but is more commonly associated with an infected cutaneous site.
Staphylococcal TSS (menstrual or nonmenstrual) is associated with extended tampon use, postpartum infections, and other sites of infection with the organism.
Treatment includes supportive care in an ICU, early empiric antibiotic treatment, and further culture-sensitive antibiotic treatment. Surgical debridement may be needed for deep-seated streptococcal infections.
Toxic shock syndrome (TSS) is an exotoxin-mediated illness caused by bacterial infection. Organisms commonly responsible include group A streptococcus ( Streptococcus pyogenes ),   or methicillin-sensitive (MSSA) or methicillin-resistant (MRSA) Staphylococcus aureus . 
Although the presenting signs and symptoms can be nonspecific (e.g., fever, chills, myalgias, headache), the course of the disease is precipitous, and shock and multiorgan system failure occur early in the course of the disease.
Staphylococcal TSS can be split into 2 groups: menstrual TSS, which occurs in women during menstruation with extended use of a single tampon or, historically, with highly absorbable tampons; and nonmenstrual TSS, which can result from a variety of staphylococcal postpartum vaginal and cesarean wound infections.
