Cause
The strep or staph bacteria that produce the
toxins that cause
toxic shock syndrome (TSS) are common, but they are
usually not harmful. Most of the time, these bacteria cause only mild
infections of the throat, such as
strep throat, or of the skin, such as
impetigo. In rare cases, however, the toxins produced
by the bacteria enter the bloodstream and cause a severe, rapidly progressing
immune reaction.
The immune reaction
that leads to toxic shock syndrome is typically linked to a lack of specific
antibodies against a strep or staph toxin. Younger
people are less likely than adults to have developed these antibodies.
Outbreaks of TSS can occur in hospitals and long-term care facilities
where people live in close surroundings.
