Virology Lectures 2020 #24: HIV and AIDS

Ғылым және технология

HIV-1 originated in the 1920s when a simian immunodeficiency virus crossed over from a chimpanzee to a human. Since then this virus has infected and killed millions. In this lecture we discuss the origin of HIV, how it was discovered, the pathogenesis of infection, and prospects for prevention and cure.

    To all who take his class: You guys are very lucky. I pay $600 per credit hour to have my professor half-heartedly read off the powerpoint slides and have to come here and watch these lectures just to learn anything for my exam. Thank you Dr. Racaniello, I really appreciate your thoughtfulness in uploading these online!

    I have not heard you mention about the polio vaccination that was happening in the Congo Belgian Congo of South Africa in the 1950s where the vaccination may have been contaminated and giving to millions

    So the virus jumped instantaneously to a hunter and then jumped from person to person immediately? I thought viruses had to evolve to their host?

    The virus has a high mutation rate and produce a lot of progeny. So yes the virus happened to jump from chimpanzee to human hunter immediately, though he would not become aware of the infection for several years. He happened to be in the right place and conditions at the time facilitated the spread of the virus between humans. There have been other known zoonotic transfers of SIV that failed to spread, however since bush meat hunting has been around for a long time there likely would have been many other zoonotic transfers over the years It was the conditions and social changes put in place by colonization that made it easy for the virus to spread.

    30:50 To treat malaria etc. blood transfusions from chimpanzees to humans were practised in some cases according to local healers etc., and need to be considerd as a transfer mode of SIV, respective HIV, to humans, too. Dear Vincent Racaniello, do you agree, or not, or else? Very good lecture! sg

    They are bloody annoying and seem to congregate around the comment sections of factual videos. Presumably in the hope of finding people gullible enough to fall for their obvious lies. You could try reporting them to KZread, though I don't know if Google care enough to do anything about it.

    Question: Is there a gland in the body - that was used in the infant stage of human life - that HIV-1 used as the reservoir point? If this is true, then removal of this gland could stop the long term effect (i.e. AIDS)

    Why is not mentioned the contaminated vaccines used at that time? It was en mass grown on monkeys kidneys etc,. Also today often vaccines contain contaminations.

    Thousands upon thousands of professional people at the top of there game have talked out about these huge mistakes, here is just a small list Neville Hodgkinson , Joan Shenton, Dr Stefan Lanka, Dr David Rasnick, David Crowe, John Lauritson, Dr Rodney Richards, Professor Sam Mhlongo , Kary Mullis , Dr Sam Bailey, Dr Mark Bailey, Dr Claus Kohnlein, Jad Adam’s , Eleni PapEleopulos , Valendar F. Turner, John Papadimitriou, Celia Farber & many many more . All the so called bias peer reviews are totally influenced by profit & all the thousands of careers that have been created by this theory.
