Does menstrual blood itself cause TSS?

Menstrual blood itself does not typically cause toxic shock syndrome (TSS). TSS is a rare but life-threatening bacterial infection that is caused by certain strains of the Staphylococcus aureus (S. aureus) or Streptococcus pyogenes (Group A Streptococcus) bacteria.

TSS can occur when these bacteria enter the body through a break in the skin, such as a cut or a surgical wound. In some cases, TSS can also develop in people who use tampons during their menstrual period. This is because tampons can create a moist, warm environment that is conducive to bacterial growth.

However, it is important to note that only a small number of people who use tampons develop TSS. In fact,TSS is a very rare complication of menstruation. If you are concerned about TSS, you should talk to your doctor.
