A CANADIAN teen has died from toxic shock syndrome while away at a school camp, a coroner has confirmed.

Sara Manitoski from British Columbia, Canada was on the trip to Hornby Island, off Vancouver Island, in March 2017 when she died.

When her bunk-mates woke and found her still in bed they thought their friend just needed a sleep-in and left to go to breakfast.

When they returned, she still hadn’t moved and appeared lifeless as her alarm was going off.

Georges P. Vanier Secondary School staff, students and emergency responders performed CPR but were unable to revive the Grade 11 student.

The night before she had complained to friends about having menstrual cramps and not feeling well, but took part in the day’s activities, according to the Vancouver Sun.

She also didn’t eat much at dinner, headed to a bonfire, and went back to her cabin at 9.50pm for the evening.

Her bunk-mates later told police they’d heard rapid, shallow breathing coming from her bed the night before.

The report said a deadly strain of staphylococcus aureus was discovered on a tampon found in place, as well as other symptoms consistent with toxic shock syndrome.

“We know there is an association. And again, it’s very rare,” Island Health Medical Health Officer Dee Hoyano told CTV Vancouver Island earlier this week.

“Certainly we know a person needs to have this particular bacteria to get sick, and then there may be something with tampon use, maybe prolonged tampon use, that puts that risk higher for developing a more widespread infection.”

Symptoms of TSS are similar to the flu, with high fever nausea, vomiting, diarrhoea, dizziness, fainting and disorientation.
