Oh oh oh! On that topic, did you know that doctors during the early 20th century used to intentionally infect people suffering from late stage neurosymptomatic Syphilis with Malaria? The Syphilis bacterium is susceptible to heat and thus got killed in the high fevers caused by the infection. Since they didn't have Penicillin back then and Malaria was a bit easier to treat that was one of the few things they could do, albeit not without risk. I think there was a Nobel Prize handed out for the method sometime in the 1920s.

My postgraduate research work in public health and tropical medicine was on malaria as it is still a disease that continues to ravage people in my country; it centered of course on the public health implications of this parasitism, not solely on its biology, though I have some ideas. To learn about its evolutionary history and how it became a parasite of humans and non-human primates eventually is truly interesting, and it has been presented clearly through this video.

I had it. Got symptoms a few weeks after my discharge so I had to go to a local hospital. They certainly didn't take it very seriously on the first night I rocked up, despite having told them I was a soldier, deployed to a known malaria zone and having told them I'd seen other guys with exactly the same symptoms. To say the triage nurses were dubious would be an understatement. Probably thought I was a softcock with a cold. Softcock?...maybe, common cold?...not this time. I sat for hours and my fever spike went down while I waited, so I went home. Went back the next night and my symptoms were horrendous, that worried them :D. On duty doctor started talking about lumbar punctures, encephalitis and other bollocks. Thankfully a bright spark called the head of infectious diseases and Dr Peter Collignon was summoned. He diagnosed Malaria, and confirmed with a blood test, what a surprise. Was amusing to hear him give some stern words about listening to a patient. I believe he now runs the ANU Medical school, at Australia's premier university.

I love your channel and videos! However, I may have some minor auditory processing issues, and I found the music in this episode very distracting. It was difficult to process what the host was saying behind the music, and I had to really focus to understand. It would be great if the music could be significantly quieter in the future, for the sake of people like me. Thanks for your consideration!

im sorry i cant get over that she's talking about death and disease in a super happy calm voice

Pretty fascinating stuff. Hopefully the insight gained can be used to help eradicate this disease.

Fantastic facts. Truth is indeed stranger than fiction. And the narrator is the icing on the cake 😃👍

Pretty cool how they discovered this! A shame we can't teach them how to go back to being algal, LOL!
