Streptococcal toxic shock syndrome (STSS) is a rare but severe and rapidly progressing invasive bacterial infection. It is caused by *Streptococcus pyogenes* (Group A Streptococcus), which produces toxins that lead to widespread organ damage and shock. While it can affect anyone, it often occurs in individuals with existing skin wounds or underlying health conditions.
Transmission methods vary. Please consult CDC or WHO resources for specific information.
