    I had two soldiers (Army medic) who contracted cutaneous Leishmaniasis in the central American jungle, so I became really familiar with it. Cut forwards to a few years later when someone came into the facility I was working in with an open lesion that wouldn't heal and when I was told the individual had been in warm countries with endemic sandflies I was like "Oh! That's Leishmaniasis!" The Nursing staff basically told me off (but you know in a kind 'you don't know medicine yet' sort of way) for thinking Zebras instead of Horses.
    Yeah after the blood results came back in they sat me down and where like "How on earth did you know that it was this rare tropical parasite that doesn't exist in this country?"

      @isaiahlawson3034 yeah, best thing is it doesn't show up until months later. One of the guys who had it didn't come to me until 3 months after we came back (we'd actually come back, recuperated, and deployed on another overseas exercise). The first guy had already been diagnosed with leish, and everyone was sort of jokingly teasing him that the open sore he had was the obvious, so he stopped me, showed me the sore and was like "doc tell them I don't have leishmaniasis!"
      Cue the obvious "uh maybe we should sit down and talk about this in private."
      The good news is it isn't just central America. Its endemic all over North and Central Africa, South America, the Middle East, and the Indian subcontinent. There are even cases of it appearing in Texas. So you don't have to worry about being deployed to Panama or anything like that.

Try to avoid sleeping on the ground; where possible deploy either a camp cot or hammock for sleeping, sandflies unlike mosquitos can get through nets but they also can't jump more than 1m off the ground.

    My wife has been infested with a parasite twice. This last time was shortly after we moved to cape canaveral. The doctors said there was nothing we could do and we just had to wait for it to incubate and exit on its own. So 9 months later the doctor removes it and hands it to me like I'm supposed to keep it. Apparently by law I have to feed it and shelter it for like 18 years. Anyway we named her Charlotte and she's celebrating her 1st birthday this month.

      Youre thinking of the "tongue eating louse" which is a type of isopod. Shockingly enough, unless a fish gets parasitized by more than one, the fish usually goes on to live a dairly normal life and the isopod just functions like a new tongue. Nature really leaves no niche unfilled.
      Oh also, they only go after fish so youre safe but there is a movie called "The Bay" where a small oceanside town gets attacked by mutated versions of these guys which eat people so maybe your brain mixed the two ideas together?

    The schistosoma slander! They're not boring at all! They're the only flatworms that are dioecious and the male essentially envelopes the female and feeds her some of the blood he gets from the host. And they spend their whole adult lives like this. Also in German they're called "Pärchenegel" which basically means "couple/pair leech", which I think is cute. Also apparently schistosomiasis is the second-most socioeconomically devastating parasitic disease according to the WHO, only beaten by Malaria

    I can't agree more. I contracted RMSF in June after a tick bite while fishing. Was not actually diagnosed until after I was cured. If you get a tick bite and then a week or so later chills, fever, headaches, tell your doctor and implore him/her to administer the tetracycline that will kill the little bugs inside you (Rickettsia). By the time you get the red spots all over, you are NOT in good shape, and on the verge of severe damage and death. Those little red spots are your blood vessels bursting as the bug attacks the lining of your arteries.

      I once ha a friend living at my place for a few years. He left, because we had dispute. On his way out he said I was a tyrant in those years. I asked him how, if he could give me examples. He had just one thing to say: "I've learned to wash my hands after going to the toilet, because I knew that you think it's disgusting to not do so."
      Let's ignore that I never told him to do so, he decided himself to do it, and thus his definition of tyrant is somewhat questionable, because that's not the topic here. I'm really baffled that to some people washing your hands after the toilet is a strange concept. I didn't even know that he didn't do that before he lived at my place. The worst part is that he worked in gastronomy for years and afterwards as a cleaning specialist in a hospital (mostly doing surgical rooms). I also always had to do dishes a second time after he was done, because he was so bad at it.
      Some people are just disgusting. While I don't have any contact with him anymore, I really hope he changed to the better, because I've heard that he has a child now.

    FWIW tapeworms are no small part of why sushi-grade fish has to be frozen (at least in north America) before consumption. Some purists dislike it but it does kill (some) parasites. With modern flash-freezing it probably does more to preserve quality (commercial fish is often frozen on the boat) than it does to diminish it anyways. Unless you were going to be eating it right off the fishhook.

    My skin itched a bit, but overall, had a blast watching this. I used to have a severe case of vermiphobia, and legit for the longest time never was really able to learn about animals fully, as I was always on the lookout for worms, I cured myself of that like in 2019-2020, so seriously glad because worms are probably one of the most coolest, fascinating animals on earth.

    I've had scabies twice. The first time was horrible, because it takes about a week before you notice. Any time after that, you notice within a day or two. The medicated bodywash we were given was formaldehyde based. Stings (and stinks), but kills them in 24 hours. Also had to basically boil our clothes and bed sheets.
    And now just the mention of them makes my skin crawl.

    About the tapeworms and that painting, 911 had an early episode in which a subplot was the firefighters/emt squad in the show responding to a call about a person in distress who was in that same position due to salmon sushi made from Pacific salmon. Another weird tidbit of info about tapeworms, the traditional cure for them in Sardinian folk medicine is a steam bath of milk and garlic under your head like you'd do with water and herbs to clear out excess mucus during a cold.

    I did a parasitology module for my degree and fell in love with Trypanasoma cruzi that cause Chagas' disease. It's another one that can stay dormant 10 to 30 years after the initial infection and cause chronic heart disease and chronic constipation depending on where the trypanasomes end up. Ibalways remember seeing pictures of patient's hearts where the muscle wall was so thin you could see through it

    Before seeing the video, I'd like to nominate Babesia spp for S tier because it's a species that has sexual reproduction in invertebrates and asexual reproduction in vertebrates (ergo, it evolved to be a parasite of ticks and being parasites of vertebrates such as dogs or humans is a happy coincidence). I just think they are neat
    Edit: I'm glad he chose malaria for a similar reason.
    Also, I'd put trypanosoma in S tier because they have a fenomenal way of surviving inside it's host. Changing the proteins it has on the outside to evade immune response. And that also makes vaccines useless which is rare. Extra poikt because one of his species has venereal transmission between dromedaries (if memory serves correctly, trypanosoma cruzei)
