Toxic shock syndrome in Canada.

Since 1976, 53 confirmed or suspected cases of toxic shock syndrome (TSS) have been reported in Canada. Twenty-two cases occurred in 1980, and by October 1981 another 21 had been reported. In Canada, like the United States, where nearly 1200 cases have been recorded, TSS appears to be associated with tampon use, although a few cases have occurred in males and in nonmenstruating women. Of the 53 patients 3 died. The enterotoxin produced by Staphylococcus aureus is probably responsible for TSS. Manufacturers of tampons have now placed warning labels on tampon boxes and information on TSS in the instruction inserts. Women should select tampons of appropriate absorbency for the various stages of menstruation.
