5 Must Know Facts For Your Next Test

  1. TSS is often linked to the use of superabsorbent tampons and post-surgical infections.
  2. The toxins responsible for TSS act as superantigens, triggering an overwhelming immune response by activating a large number of T cells.
  3. Symptoms of TSS include high fever, rash, low blood pressure, and multi-organ dysfunction.
  4. Diagnosis of TSS involves clinical evaluation and laboratory tests to identify the presence of bacterial toxins.
  5. Treatment includes administration of intravenous antibiotics and supportive care to manage symptoms.
