    sounds like the combination of s and l types are a new type possibly mutated and should be called something else. like it is developing and building. if it builds, won't it be even more difficult.

    Only the Chinese authoritarian CCP could lock down and quarantine major population centers. The US population would complain, rebel, PC every effort to ineffectiveness. The combination of the complexity of this situation and ignorance leaves no other option than authoritarian action and responses. BTW: WASH YOUR HANDS.

    The Western governments won't be able to "lock down" in the way China has because the populace is not terrified of the police and government as the Chinese are, that is the one advantage of having a brutal socialist regime in charge.
    I think the West will lock down without being told to when people start dropping dead in the streets, nobody will leave their homes and the economies will collapse.

  34. Avatar

    I was reading that most people are catching the S type now since the L type stopped spreading and it's struggling to survive. The S type being more mild. Which is why new infections are showing mild symptoms. Which is good news. I think the reason why China saw such a high infected and death rates is because type L was the one spreading. Since China shut everything down to L isn't able to spread.

    Question? If RH factor blood has no protein on outside of cell wall verses positive having both inside and outside proteins could this lower receptions? Anyone can receive o neg blood without a shock reaction. Obviously there is a huge difference in this DNA bloodline. Perhaps their should be more evidence of their push for DNA databases.

    Doctor Campbell, you absolutely must not stop making these videos for the duration. I will contribute to your project and I encourage others who have come to rely upon the excellent instruction provided. Doctor, you provide both calmly-delivered information and a degree of comfort to those of us who worry excessively. The smattering of humor is a delight and makes digesting this topic somewhat more manageable. Thank you so much for the extensive time and effort you expend and the very wonderful lack of self-serving motives that accompany many other channels.

    I hope I survive to the point where a vaccine is available to me. I seriously doubt some of my family members will survive any infection. 🙁

    But wait….they didn't lock down until AFTER early January. Meaning the L type is likely what has spread around the world. At the rate of spread, if the S is less infectious, you would think we would be seeing a SLOW DOWN of disease progression but instead we are seeing an INCREASE of progression. I am not a Scientist Dr. John, FAR from it…but the DATES don't line up to the theory that it is S spreading and L has slow downed. In Washington State (my neighbor!) We have 12 deaths and only 109 confirmed cases. This tells me there are THOUSANDS infected because of the R-Naught and the 3.4 mortality rate (increased by a W.H.O. specialist)…what are your thoughts on this? And one more thing, TESTING has slowed down. Here in the U.S. they have hardly tested ANYONE. The L type is not PROVEN to be slowed down because there is no testing being done to confirm the TYPING of the cases…tablets here in the U.S. where travel to and from China is greatest.

    I believe there is a possibility the S type is more prevalent because it's less severe and less virulent. Weird as it may sound, people with light disease are more likely to misrepresent it as a regular cold or flu. These people are then less likely to visit a doctor and lay down in bed as they instead push through, go to work etc. Others then are less likely to worry because "I ain't got the symptoms and Jeff's fine too, it was probably just cold.". This way the S type can than happily spread from people who go to lock down too late and take no precautions. Hell, I have cold and didn't stop working. It's almost over though, finally my nose can heal up again.

    If this is the narrative Chinese scientists are pushing to pat themselves on the back for their actions, I’m very skeptical. That’s the exact kind of propaganda that CCP would want their citizens and the rest of the world to believe and admire their government’s efforts.

    This is a cold. It spreads like the cold, is as incurable as the cold, is as mild as the cold IN THE BEGINNING. It then attacks deep lung surface cells, kills them, and leaves holes in the surface, where pneumonia bacteria can start the attack. There is no way to really stop the spread. What we should have started with from the beginning, was to shield those who can be most severely affected, old people and those with illnesses that can make the infection dangerous for them.

    There is aerosol spread, so washing Your hands is not a good enough prevention. With the precautions taken in most countries, what will happen is rapid spread of the infection. Locking down air traffic, trains, buses, ships and so on can help, as well as closing schools, restaurants, stadiums and so on. But this will only slow down the spread.

    I think we finally must realize that this epidemic must run it's course, and there is no real hope of stopping most of the population from getting infected. So as I said earlier, shielding the old and others most likely to suffer really serious effects. That means homes for the elderly and neighborhoods with an old population + people in risk groups should have been the ones isolated from the rest of us, and thereby from the risk of getting infected, as long as possible, until a future cure is at hand. I do not see the WHO, CDC and public health officials making this logical conclusion, or acting upon it.

    When this first hit Wuhan I thought it was an accidental release from the lab. They rounded up all of those people and released another less deadly virus because it would have looked incriminating if nothing spread. This confirms it. Kind of a relief, really but I feel bad for Wuhan

    On the recent developments in NY. There was “no indication” that “casual contact,” such as riding a subway with someone who is sick, is “going to increase the risk to everyday New Yorkers,” said Oxiris Barbot, the city’s health commissioner(from how the flu on steroids spread in New York)…… officials in the government are still complacent about anything regarding this virus.

    This is a disaster. Boris Johnson just told ITV's This Morning programme: "One of the theories is perhaps you could take it on the chin, take it all in one go and allow the disease to move through the population without really taking as many draconian measures. I think we need to strike a balance." . This is a catastrophe as it will mean thousands of ICU beds being needed to have any chance to save lives. As we don't have the beds or the staff what he is saying is that the Government wont try to save people, just let them die untreated in their homes and let the virus die out on its own. This will no doubt say the government a lot of money. All they need is body bags and a truck.

    question: If the L mutation came from the original S-strand, then could the S-strand cases still turn into L-strand? Where does this mutation take place exactly? in the human body? it is a little difficult to get our heads around it as lay people. Thank you.

    Let’s reason together. => If the initial strand mutated after a certain number of infections, I don’t understand why both strains might not mutate again. Perhaps after approximately the same number of additional infections as the initial number of infections before mutation. Using the reported numbers of perhaps 50,000 reported infections when the samples that formed the basis of the study that formed the basis of this video, were collected – we know the actual number of infected people is always higher than any report of infected people, but assuming the ratio of reported number of infection to actual number of infected people is the roughly the same, would it not be reasonable that at least a potential additional mutation would occur each time each strand infected sufficient people to have a reported infection of an additional 50,000 people? => Is it not also reasonable to suggest that some percentage of these mutations will continue to be of infectious concern? (Perhaps, there were many previous mutations of the virus and only the one mutated strain was of infectious concern.) This would seem to suggest that there will be many more strains before this pandemic is over. => If one assumed that one hundred times more people were infected than reported, than for every half million infected people, there will be a new strain that is of infectious concern. It seems reasonable to me that those moving forward with vaccines need to anticipate this potential and plan for different strains. Everyone can do the math to see how many different strains might evolve if the estimates of 80% of the world’s population are infected. Also, everyone can do the math if one assumes that only one tenth or half of that estimate actually occurs. => Also, it doesn’t seem unreasonable to suggest that the more dangerous strain may also not be the most infectious, so we may continue to see the same ratios of these two strains. =>. Lastly, if I remember correctly, at about 14:30, is it not reasonable for a resurgence of the number of infected if social distancing behaviors change, changing the then current R0? Is it not reasonable for resurgence not to just be a risk for future new strains, but a risk for changed behaviors, even if the disease is not at least biphasic.

    Great discussion of new strain, thank you. More easily transmitted is one of several factors contributing to Ro and it is Ro that is important in how two strains evolve in their prevalence in human populations. Thus, the Ro can actually be lower overall for L strain compared to S strain because of these possibilities which need to be researched:

    (1) If L strain infected time window to infect others while asymptomatic is sufficiently narrower than S strain Infected, the reduced time window of asymptomatic transmission may outweigh the higher transmissibility effect on Ro – net effect is a lower Ro.

    (2) Even when infected enter symptomatic phase, most present only mild symptoms similar to the common cold. Therefore, it is unlikely that those with mild symptoms would feel the need to go to a hospital or clinic, just get some over the counter cold medicine and otherwise go about ones everyday routine – all the while spreading the infection. However, if the L strain has more severe illness, a higher proportion can be identified and isolated, preventing further spreading by that individual which lowers Ro.

    (3) If more severe illness leads to higher fatality rate and more rapid progression to death, then those infected with L strain will have less opportunity to infect others compared to a S strain infected spending weeks recovering all the while infectious. Importantly, L strain would have a lower nosocomial (spread in hospital settings) specific Ro and hospitals a a major concern as a breeding ground for clusters of infections.

    We have had the two forms since January, as I wrote to you a while back. If you look at the graphs you will pretty much be able to see when it happened (Notice the difference from January 17). The Chinese study was presented on the net, but was ignored by a majority. Authorities and the mass media have been more busy telling people that this is just a flu, that they got it covered, and that face masks doesn't work (which you all will come to see is a f-ing lie by authorities caught with their pant's down, and wanting to get their share). The only reason for bringing up the mutation now is because it sadly for them got out that people infact get the disease twice. Both the S and the L. That could point to that vaccines wouldn't work, and prevent them from keeping the masses calm by constantly telling stories about having a vaccine ready soon. Apperently it's easier to admit that they have to make two types of vaccine by now, which probably soon won't be enough anyway because the virus keeps mutating.
    Forget stupid conspiracy theories etc. but keep your eyes open. We don't know why, but one thing is clear: Authorities are lying their butt off.

    Is “viral interference” a real scientific based thing? Perhaps you can make a future video discussing this concept.

    The problem is that the lockdown in China happened after the horse had already bolted due to a government cover up. Meaning the virus had spread globally over a short period of time. Therefore theres just as much of a chance that it could have mutated into the more virolent L strain as the milder S strain.

    82 Cases here in The Netherlands now, double as of yesterday. And testing results are now delayed by 72 Hours.

    They're really dropping the ball here. I read the RIVM and GGD didn't want to test a couple that came from a honeymoon in Japan, even though they had a 38C fever. They said they didn't come from a high risk area, so testing isn't needed… They're also telling people that do test positive to stay quiet about it.

    The RIVM and GGD also keeps believing there is no spreading risk by touching your mouth and face. It's only being transmitted via coughing as far as they're concerned. Children can just go to school as well, no risk of spreading they said until people get symptoms.

    I just fail to understand this behaviour from our government.

    This trust in "clever scientists" and "vaccins". I'm not against vaccins, but it's been two months and already there's a mutation. How many strains in 2021?
    What is glaringly obvious is that this came from a chinese lab and that all countries have to openly share their research data about this.
    Since the WHO completely dropped the ball, and didn't limit travel in the crucial period a month ago, some other more trustworthy organisation will have to do this.
    Openness is the key.
