Toxic Shock Syndrome is a very rare, but life threatening disease. It is commonly associated with the use of tampons, but it is not the only way it arises. This disease derives from toxins, which are produced by staph bacteria, but can also be caused by group A strep bacteria. TSS can come from skin wounds, and even surgery. TSS requires immediate attention by hospitalization.

     Symptoms include confusion, diarrhea, high fever, muscle aches, organ failure and burns. The most common and severe are kidney failure, heart failure, liver, shock, and death. Treatment, which won’t always resolve the issue, include dialysis, antibiotics, fluids (IV), meds to control blood pressure, and presence in the ICU for continuous monitoring.

     In a simple way, bacteria enter the body through an opening in the skin, which could be in various ways. Many cases are associated with tampon use, but is much less common in the more recent years. Other cases include recent childbirth, use of diaphragms, and open skin wounds.
