Your body usually does a great job defending you from all kinds of viruses, fungi, and bacteria. However, there are some pathogens out there that can hide from your immune system and stay dormant in your body, waiting for their opportunity to strike.

Human immunodeficiency virus:
The Brits bombed a Gruinard Island in 1942 with anthrax to test it's effectiveness, making the island uninhabitable for 48 years. In 1986 they deconned the island with formaldehyde diluted with sea water and it was officially declared habitable in 1990. Since then they've been raising sheep on the island without a reappearance of the bacteria. Nasty stuff but apparenty there is a fix.
Us 90's babys and earlier rock!!! What's that about herpes zoster you say? Before 95 you say? Damn.
I was born April 26 1990 and I'll never forget the day during naptime in kindergarten that I asked to go to the nurse and was shortly after sent home with chicken pox.
I was part of a chicken pox vaccine study for Kaiser Permanente as a child, and I ended up contracting chicken pox three times through out my life. Once when I was 5, again when I was 8, and the last time when I was 13. Horrible experiences each time.
P.S. No, the vaccine didn’t cause Autism. Vaccines don’t do that.
I had an adult case of the chicken pox at 7. All over my whole body including inside my mouth and down my throat. I missed like two weeks or school and it was brutal 😖😖 I’m glad kids don’t have to go through that anymore
Toxoplasmosis also creates a psychological change in infected rats, it makes them less cuatious of cats, in fact they seem calm and happy around cats. Toxoplasmosis is known to infect the brain of humans (thus schizophrenia, alzheimers etc.). Yet no research has been done to see if the infection can also cause a psychological change in humans to favour cats. This might be the source of the "Crazy Cat Lady" stereotype. Someone who suffers from schezophrenia, and the anxiety that comes with it, and are only calmed by the presence of many cats, increasing the chances of toxoplasmosis going from cat to human and back again.
I sure like all of your channels. Every once in awhile I sit down and give your channels 2-5 hours of my time.
The trouble is I am disabled so I only represent a like to you and advertising on YouTube is being withheld for whimsical reasons so it is possible you are not monetized. Thus I am grateful to your list of those on patreon who can send you what they can afford. I truly thank them for keeping everyone working over all these years.
We are all equipped with the best treatment for shingles... its your own earwax! Seriously, but don't just take my word for it, rub even the slightest amount of your own earwax directly on the rash and you will find immediate soothing relief! I have found that it doesn't seem to return, at least not for 3yrs from my personal experience.
Apparently our own ear secretions have antiviral properties.
My inmunology teacher told us that given how terrible and deadly tuberculosis is (the second time round and when it is antibiotic resistant), she would rather get HIV than TB. You can treat HIV and survive, even live longer than someone without it (if you follow your treatment religiously). With TB you have to be lucky.
Your immunology teacher should think again about that. I have been living with HIV since 2006, when I got Pneumococcal Pneumonia and almost died (which is how I found out I was HIV+). With TB, you can take your meds and get rid of it completely and never have to take them again. With HIV, you have to take your meds, everyday, at around the same time, for the rest of your life, or you can have what they call a "Breakthrough", ie a virus resistance to one or more of the meds. Then you better hope that one of the other meds will work on your breakthrough virus. Even with taking your meds religously, you can still develop a breakthrough virus like I did. I am fortunate that adding a 4th med got me back to the "undetectable" status.
Also, with HIV, your immune system is still compromised for the rest of your life, so any other virus or infection you get can cause your immune system to fail or falter, causing an HIV mutation, which starts the whole "Better find another med that works!" scenario.
Right??? I got chicken pox as an adult and it was the worst!!! I wouldn't wish that on anyone. I had it about 5 years ago, I got it just from being around someone with shingles. I assumed I was vaccinated as a child but I wasn't.
You didn't talk about malaria, some variations e.g. Plasmodium vivax and P. ovale sporozoites can stay dormant in liver cells for years, there have been cases where malarial symptoms have appeared 45 years after inoculation.
It makes evolutionary sense that super-deadly pathogens would become these sleeper agents. If the pathogen killed whoever it infected right away, then all of its host population would die off, with the pathogen.
I got chicken pox when I was a toddler or young child then years later when I was 11 I got shingles 😥 it was so painful and terrible, in a band around my left rib cage that felt heavily bruised but it wasn't at all.
Fun fact: Toxoplasma gondii makes mice overcome their fear of cats, in many cases described as a love feeling for cats. Cats then eats mice, toxoplasma replicate inside cats, cats poop, mice eat poop and the circle of life continues (you know... for toxoplasma at least)
SciShow, you could have just as easily titled this "Can Make People Sick" so the fact that you titled it "You Sick" implies you want us to think you're talking to each of us specifically. Even in the video it was as if the annoying one was trying to scare us. Everything scary was directed at "you" and everything calming was directed at "people" or "they".
You can kiss my ass specifically...
I would also clarify - Toxoplasma gondii most certainly *is* treatable. It responds to a number of antimicrobials - including Septrin (Trimethoprim/Sulfamethoxazole), Pyrimethamine, Clindamycin (I think). Indeed we give prophylactic septrin to many at risk groups - in particular HIV/AIDS patients (with immunosuppression), patients on highly immunouppressive chemotherapy etc. It does require long courses of therapy then prolonged suppression.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
