2. Do you agree with this info that is circulating from an MD about the validity of antibody tests? “The big flaw with these antibody tests is the cross-reaction with other Coronaviruses. This is plainly stated in the package inserts. A positive IgG quicktest DOES NOT MEAN you have IgG antibodies or are immune to Covid-19! It means that you have IgG antibodies to one of the Coronaviruses (maybe or maybe not Covid-19).”

3. Masks and gloves should be handed out freely to all. Nobody should have to pay with there lives..

4. Sciences! Romance! Pillbugs and Medical mysteries! It's MedCram. 🙂

5. There's a theory that the symptoms are similar to high altitude pulmonary edema and that the medication used on HAPE can be the answer, what are your thoughts on this?

6. EXCELLENT RESEARCH!!!!
   WE CANNOT BEGIN TO TELL YOU HOW APPRECIATED YOU ALL ARE .
   WE'LL LIKELY MAKE PROGRESS . PWW

7. * in this series:
   
   ** vid 25 is numbered 25, vid 27 is numbered 26, & vid 26 is not numbered ?

8. Doctors shouldn’t make their decisions on what the FDA does or does not decry you don’t work for them: they don’t work for your patients:if you are depending on the FDA to understand if, how, and why a test or medication works: then you should consider a different field.

9. Preciate the knowledge!

10. When will this Virus just End

11. How refreshing to hear actual facts!!!

12. Thank you so much for all of your efforts.

13. I did some research and….
    The pandemic started in 2019, 5 years after Ebola, Ebola started 5 years after the Swine flu pandemic, and the Swine Flu started 5 years after the Avian Flu…
    Avian came from birds, Swine came from pigs, Ebola came from bats, Corona comes from bats

14. So will we see a growing curve showing the number of people with positive antibody test results?

15. Question. What is Diamox? what is it used for ? Thank you

16. How will gain any ground with herd immunity if we all are staying home?

17. Another thought would be enhanced Vit D production in Forest excursions over smog filled city walks, with consequent immune function benefits

18. like si entiendes mi comentario!

19. Excellent

20. Tell us about extracorporeal membrane oxygenation, or ECMO

21. Endangered species ?

22. Loved the pillbug story!

23. Hi, I have been very depressed and anxious lately because my parents are older than 60. They have not yet understood the gravity of the situation. They're are sad because I don't visit them that often nowadays cuz of the virus and they take it personal. I read a Harvard article that said the only chance we have to fight this virus is that more than 65% of the population gets infected and they're are no likely to survive if they get infected (I'm crying while writing this). And others say this social distancing will last till 2022. I'm seriously very depressed because of my parents. Here in Guatemala we've only 180 cases but the number increases everyday. I hope I can hear better news from you in the future. If you're also feeling depressed because your parents or friends or grandparents are seniors, please reach out to me.

24. It is ludicrously impossible to calculate how many asymptomatic people there are in order to calculate the rates of any other symptoms. It could be that the tests (which according to the BBC and NCBI may yield up to 80,33% false positives) have fooled us into thinking that the infection and mortality numbers are up to 5 times higher than reality, OR it could even mean that billions around the world have already had it and are already immune and the only ones suffering today are the unhealthy boomers.

    Medical is the 5th preferred profession of psychopaths (Journalism is 6th and Law Enforcement is 7th). Medical Error is the 3rd Cause of Death in developed nations according to John-Hopkins and the WHO; Doctors kill over 14 thousand innocent people indiscriminately every single day. On average Medical Professionals are 15x more lethal than CoV19.

    According to the CDC, the Common Cold (do a search right now for "Common Cold Causes" and you'll find the scientific name "Coronaviruses") kills 600 thousand per year. At this rate, at this late month in the yearly Cold Season, CoV19 (19 meaning "from 2019", novel meaning it is, like every single year, a new mutation) will just be over HALF as deadly as 2017's Common Cold was was (646 thousand deaths according to WHO).

    Smoking is 20x more lethal than CoV19 according to the CDC, but tobacco will never be banned and no one is telling you to wear a mask around smokers.

25. Can you really assume that actual virus is present from RNA found on a swab (or on any other surface, for that matter?) I remember a researcher at a lab I once worked at mentioned the pesky environmental RNAses that kept breaking down his experimental RNA before he could use it, so perhaps one can assume that the RNA is broken down almost immediately once the capsid has broken down? However, there was a study in Nebraska that looked at coronavirus which had disseminated throughout a building to varying degrees and they made a distinction between RNA and actual virus, as they were using PCR and wanted to make sure that readers realized it was actually RNA they looked at and not actual virus. Curious to know what is actually thought about RNA vs. actual virus in such cases.

26. Clarity thank you so much – greetings from UK.

27. Keep your distance keep clean day to yourself I'm staying to myself I'm 63 years old I'm homeless hate to say that but I keep to myself I just pray every day gets better and we all get together and fight this terrible things happening around the world God bless us all and God is putting us to a to test he wants it all to respect the world we live in take care of our world our planet God bless us all and rest in peace for the ones that passed away

28. There have been reported cases of people getting re infected. We still do not know if those recovered actually develop antubodies. I think we "assume". Thanks man. This is very helpful. Relevant information.

29. canada has a test kit see … https://www.youtube.com/watch?v=Uf_qzepW7EU

32. Banksters are sure spending a lot of taxpayer money on their crisis actors. Too bad they all can be recognized from far away…

33. Covid 19 e Sida ultima faza

34. Very informative

35. Technical questions need to ask any MBBS, immunologist or Lung Doctors (pulmonary specialists)
    .
    (1) GENERAL TESTING QUESTION
    ——————————————
    .
    (1.1) Say a normal person is tested for 20 most commons flu except corona-19 and also tested for common killer bacteria like TB etc. How many of of normal persons will test positive for these flu?
    .
    ==========
    .
    (2) IMMUNE SYSTEM QUESTIONS
    —————————————-
    .
    (2.1) Say a patient of age 20 suffers form a specific flu virus and he recovers. Will his body "remember" the cure ? i.e. is he likely to get severe infection from that specific flu virus again? Even at age of 60 years or 65 years, where he has normal health?
    .
    (2.2) There are 20 strains of corona viruses. Say a person is infected with one strain, he gets some cold and recovers,. Now say he is infected with ANOTHER strain after a few years. Then will antibody made for previous strain now be useful? Or, body may gave to develop a new strain?
    .
    ===================================
    .
    (3) LUNG RELATED QUESTIONS
    ————————————-
    .
    (3.1) say 2000 patients have reached covid-19 infection to the point that they need ventilators. Say because of shortage, only 1000 are given ventilators and 1000 are not, Then in each set of 1000, how many will survive STATISTICALLY speaking. And pls note — we talking about covid-19 patients ONLY
    .
    (3.2) Any data from Italy? i.e. of all patients who were put on ventilators, how many survived? Also in Italy, of all patients who were given ventllators, how many survived? And those who did not survive, how many days did they live longer for?
    .
    (3.3) Ventilator has many functions. But say one wants to make covid-19 specific ventilator / respirator. Then what features can be ignored
    .
    (3.4) Ventilator are made with 99.99% reliability in mind. But say one chooses to make 99% reliable ventilator i.e. if 1000 ventilators are used for 1 month, 110 may fail. Then what other modifications can be allowed to save production time?
    . …..

36. Is the RNA test highly specific for Covid-19 or can this RNA marker be affected by other things?

37. This is really great news

38. Now is the time to take true action and repent from your sins, turn from doing evil, and pray to God to forgive us all. This is the only true method that will save lives.

39. How come HIV patients can't make adaptive immunity…? If they find a vaccine for covid would they also use same thing for rx of syndromes like HIV? Can you do a comparison video?

40. Please help I'm having mild symptoms but it has been 4 weeks already and still few days I get better than worse again..

41. Doc, as it replicates COV 19 bonds to and destroys the protective cover on the iron ion within the hemaglobin molecule. The patient's body becomes starved for oxygen O2 and dies..

    Recovered
    COV 19 patients recur and become contagious a second time. You need to check the most recent data, PLEASE ! ! !

42. Conspiracy Theorists: sounds like a bunch of made up mumbo jumbo in order to cover up 5g

43. Biggest question is why no scirnllent8st is creating an immunization against this

44. Why is there no word about covid-19 and gasoline vapour? It kills all viruses in a second.

45. I wish we had more doctors like you! You are a true Godsend!

46. If you have a severe case of coronavirus watch the link below

    https://www.youtube.com/watch?v=6LkKt9FE3_Q&lc=UgwB2tKhJzOaWruDoyx4AaABAg&feature=em-comments

47. Please use the Fabunan Anti-viral injection, it can help in Covid-19

48. Thank you for your COVID19 posts. Seriously i feel your post have done a public service to keep people aware of what is really going on, knowns, unknowns, and your channel has stayed away from politics THANK YOU. I have started watching many of your other videos, thank you very much for educating us.

49. Hi Dr. Seheult,

    Perhaps if you are not too busy, maybe you can confirm or refute this:

    I was having a conversation with a friend about plasma therapy for COVID patients. With my limited knowledge(A.S in Biology), I tried to make the case that this type of therapy probably has high efficacy and can save many lives provided there is sufficient blood plasma in the hospitals. His argument was that it wouldn't matter because he heard stories of people being re-infected. I told him it wouldn't matter if someone is infected a second, third, fourth time etc., because infection doesn't necessarily mean sickness or symptoms. I say this because I remember from my immunology course that if somebody has sufficient antibodies for a certain virus, when the virus enters that person's body it will replicate briefly but then there would be a very rapid immune response which will prevent the person from getting sick. Right?
