TSS is pretty rare.

"The symptoms of TSS include sudden high fever, a faint feeling, watery diarrhea, headache, and muscle aches.....Toxic shock syndrome from staphylococcus starts suddenly with vomiting, high fever (temperature at least 102 degrees Fahrenheit [38.8 degrees Celsius]), a rapid drop in blood pressure (with lightheadedness or fainting), watery diarrhea, headache, sore throat, and muscle aches. Within 24 hours, a sunburn-like rash appears. There also may be bloodshot eyes and an unusual redness under the eyelids or inside the mouth (and vagina in females). After that, broken blood vessels may appear on the skin. Other symptoms may include: confusion or other mental changes; decreased urination; fatigue and weakness; thirst; weak and rapid pulse; pale, cool, moist skin; and rapid breathing.....

Females can reduce their risk of TSS by either avoiding tampons or alternating them with sanitary napkins. If a girl uses only tampons, it's important to choose tampons with the lowest absorbency that will handle her menstrual flow and to change the tampons frequently. Between menstrual periods, it's a good idea to store tampons away from heat and moisture (where bacteria can grow) - for example, in a bedroom rather than in a bathroom closet. Because staphylococcus bacteria are often carried on dirty hands, it's important to wash your hands thoroughly before and after inserting a tampon."
