Toxic Shock Syndrome: Way Beyond Tampons


[ ♪ Intro ] If you’ve ever read the fine print on a
box of tampons, you’ve seen the dire warning that they can cause Toxic Shock Syndrome, which is quote “a rare disease that can be fatal.” And that’s true. But toxic shock syndrome, or TSS for short,
isn’t limited to tampons. In fact, in the U.S., a lot of cases have
nothing to with menstruation, and almost half of all cases are in males. Which is why everyone should know what it
is and what the warning signs are, even though your odds of getting it are really, really
low. The onset of TSS is usually sudden, things
like high fever, rash, and low blood pressure all appear seemingly out of the blue. The disease quickly progresses until your
skin is literally peeling off and multiple organs fail. And bacteria are to blame. Almost all cases can be attributed to infections
with either Staphylococcus aureus (the infamous “staph”) or Streptococcus pyogenes (better
known as “strep”). And that’s because both of them can produce
toxins that act as superantigens. Your immune system is constantly on the lookout
for foreign substances or other threats, which are collectively referred to as antigens. These antigens activate the immune system,
including B cells, which produce antibodies, and T cells, which directly attack invaders
and signal to other cells to ramp up defenses. As the name implies, superantigens trigger
your immune system in a big way. Instead of activating 0.01-0.1% of T cells
like normal antigens, they set off 5-30% of them. For those doing the math, that’s 50 to 3,000
times the normal immune response. The immune system gets so out of control that
it actually starts damaging your own tissues. If left unchecked, it can end up literally
killing you. Frighteningly, the main two types of bacteria
involved in all this aren’t rare. A lot of people have them harmlessly growing
on their skin or other parts exposed to the outside world, like their mouths. For example, a study of over 100 healthy preschool
children found that a little over 15% were carrying strep and more than 50% were carrying
staph. And even when strep and staph do cause problems, the illnesses are usually pretty minor and treatable with antibiotics. Don’t get me wrong, having strep throat sucks, but the vast majority of the time, it’s not life-threatening. What’s not well understood is why they go
from causing mild illnesses to potentially killing you with TSS. Not all strains have these superantigens,
and even those that do don’t produce them all the time. Microbiologists have found that the environment
the bacteria are living in can turn the genes for them on or off. And that’s where tampons come in. About half of staph-related cases are associated
with menstruation or tampon use. Tampons are kind of like petri dishes, providing
a warm, moist environment for bacteria to grow. Which is why it’s important to change a
tampon every 4 to 8 hours. The longer a tampon is left in, the more time
bacteria have to multiply. And other factors may be at play, too. Using a tampon that’s really absorbent can
dry out the vagina and cause tiny scratches that allow toxins to enter the bloodstream more easily. Another hypothesis is that the tampon introduces
oxygen into the vagina, which triggers a shift in bacterial gene expression, making it more
likely to produce superantigens. And all of this is why, in the early ‘80s
when super-absorbent tampons were really popular and people were just leaving them in for days,
there were a lot more tampon-related cases. But anything you put inside your body and
leave there for a while could do the same thing, hence doctors flipping out over those
jade eggs. Now the other half of staph-related cases
come from all sorts of staph infections, including ones that occur after surgery, childbirth,
burns, skin lesions, or even the flu. And strep-associated TSS is pretty much a
complete mystery. Many cases seem to stem from infected skin
lesions. But in others, the patient doesn’t have
an infected cut or scrape, or any other obvious way for the bacteria to have entered their body. And doctors often can’t figure out why the
strep started to grow out of control or produce TSS-inducing toxins. So if you’ve ever gotten an infected cut
or had strep throat, there was a chance, albeit a small one, of you developing TSS. Treatment usually involves supportive care
like fluids and medications to keep blood flowing around the body, as well as antibiotics
to knock out those bacteria. In severe cases, doctors may also give the
patient intravenous immunoglobulin or IVIG. This is basically the pooled antibodies from
the blood of 1000 or more human donors. For unknown reasons, some people produce really
effective antibodies that neutralize superantigens before things get out of control. And most people develop antibodies against
some of the common superantigens by adulthood. So it’s thought that IVIG can help dial
back the immune system, although, not every trial has found it significantly improves survival. All in all, staphylococcus-related TSS has
a fatality rate below 5%, but streptococcus-related TSS has a fatality rate of 30-70%. If all this has you super freaked out just
stop for a second. Take a deep breath. Yes, TSS is scary, but the chances that you’ll
get it are pretty low. In the US in 2016, there were just 323 identified
cases of TSS, about 90% of which were associated with strep bacteria. And they were split almost 50/50 between males
and females. That’s about one case of TSS in every million
people. And there are steps you can take to lower
your risk. These include using tampons correctly, properly
caring for wounds, washing your hands, and alerting your doctor early if you think you
might have an infection. Thank you for watching this episode of SciShow! And thanks as always to our patrons on Patreon. We couldn’t do what we do without them. If you want to support our team and help us

  1. I swallow 1 whole clove of peeled garlic for one week before going to bed every single day. Do this once a year. This natural antibiotic is so powerful it just kills all heavy toxins in the body. I never used drugstore antibiotics because of this. Girls please never use tampons or a plastic cup because the combination of synthetics and plugging blood is dangerous, u can loose your legs or getting trouble getting pregnant in the future because the blood doesn't flow out of your body naturally so where does it end up!?

  2. I have a fever Rn, idk if it’s cuz I’m ill but it started as soon as I started using tampons which was a few days ago as pads were just annoying me. So I’m so confused. And apparently a sign of tss is a fever

  3. Thanks for the comforting part near the end. I needed that deep breath because even though I don't where tampons, my health anxiety was rising rapidly.

  4. Yeah that’s why I wear pads, sitting in your own blood is a little uncomfortable but tbh I’d rather sit in my blood than be dead so yeah xx

  5. In a patriarchal society, women are always devalued. Men get everything and don’t let women thrive. Women power is always in existence. But thinking about it, are tampons a form of extinct women slowly. Tampon genocide to think of it. Is that a way to get rid of women in the world, by including harsh chemicals that we put in our bodies, delicate parts for our period which is part of nature? It makes me think alot.

  6. Someone help me, i tried using a tampon for the first time but i didnt insert it correctly i started feeling faint, so i removed it immediately, i want to a gp the next day, but he seemed fine about it. My period has jus ended n sometimes i feel faint. Am i over reacting?

  7. I thought watching this would calm my constant anxiety about having an infection. Oh how wrong I was. Still a good vid though.
