Is there an infection besides staph that can be caused by a tampon being left for 5-6 weeks?

TSS: Toxic shock syndrome (TSS) is a rare, life-threatening complication of certain types of bacterial infections. Often TSS results from toxins produced by Staphylococcus aureus (staph) bacteria, but the condition may also be caused by toxins produced by group A streptococcus (strep) bacteria and some others. As you suspected, this is often caused by a tampon left in the vagina. See Dr. if your case.
