In the United States, almost all women use tampons. Each year, there is a very small handful of cases of toxic shock syndrome, and not all of these cases are caused by tampon use. Women who do not change their tampons regularly or who use tampons while they have an internal wound are at risk of developing toxic shock syndrome from tampon use, but even this risk is very low. So calm down, ladies. You are not going to get any diseases or infections from using tampons assuming you change it and bathe regularly. You should just educate yourself about what toxic shock syndrome is and how to keep yourself clean.
