Updated - Reuters: New coronavirus losing potency, top Italian doctor saysLast edited Tue Jun 2, 2020, 12:01 PM - Edit history (2)
Updated/ disputed from WHO (Washington Post):
https://www.washingtonpost.com/health/experts-dispute-reports-coronavirus-is-becoming-less-lethal/2020/06/01/8f8ace7c-a432-11ea-b619-3f9133bbb482_story.html?utm_campaign=wp_post_most&utm_medium=email&utm_source=newsletter&wpisrc=nl_most ROME (Reuters) - The new coronavirus is losing its potency and has become much less lethal, a senior Italian doctor said on Sunday. “In reality, the virus clinically no longer exists in Italy,” said Alberto Zangrillo, the head of the San Raffaele Hospital in Milan in the northern region of Lombardy, which has borne the brunt of Italy’s coronavirus contagion. “The swabs that were performed over the last 10 days showed a viral load in quantitative terms that was absolutely infinitesimal compared to the ones carried out a month or two months ago,” he told RAI television. Italy has the third highest death toll in the world from COVID-19, with 33,415 people dying since the outbreak came to light on Feb. 21. It has the sixth highest global tally of cases at 233,019. https://www.reuters.com/article/us-health-coronavirus-italy-virus-idUSKBN2370OQ?utm_campaign=trueAnthem%3A+Trending+Content&utm_medium=trueAnthem&utm_source=facebook&fbclid=IwAR2RIvPaynd2BkBZ3ipJXScSCaLDewLN2RFIUaSNcI2rsi7J_LrHZ_xrdkc

27. Well he is quoted as suggesting they need to open the country.
That alone could be motivation enough to even convince himself that the virus is less potent. He is claiming that based on the viral load from swabs.
I am not sure that less viral load from the swabs he got would suggest that the virus is different or less potent. |

Physicians can be as careless, arrogant and self-promoting as all the rest of the species (sometimes more so). What I do care about is .. whatever his motivation, his bulls**t and bluster helped to kill a lot of people. And there were lots of "interesting articles" written about this man and his "findings" too .. along with people drinking fish tank cleaner.

In fact, I have yet to see a person that wasn't wearing a mask. A Doctor should know that plays into viral loads that a person takes in. I really hope that he doesn't induce Italians to stop wearing masks.

(not at all unusual for corona virus) not a single one of which has shown any tangible difference in infection or transmission.
And the idea that all of a sudden all of the SARS-Cov2 being seen in Italy has morphed into a less infectious (and therefore less efficient) strain ... I'm going to wait for a LOT more confirmation on that one. |

13. Does that make sense?
That the entire virus in the country spontaneously mutated and now the only thing spreading in the country is a less lethal form of it? To do that would require two things: 1 - that a new strain has in fact become less deadly and 2 - that this new strain transmits vastly more readily than the old strain, so much so that it overwhelmed the original virus in the country in the span of a couple of months.
The alternative explanation, which makes more sense to me, is that when people are contracting the virus now they're getting lower doses of it and reacting less severely because of the rise of so-called NPIs (non-pharmaceutical interventions). That would be things like social distancing, frequent cleaning, face masks, making sure your immune system is working better, taking vitamins/supplements, getting adequate rest, etc. Those should help people get a head start against the virus if it hits them. Also doctors are surely better able to treat people now than they were two months ago. |

45. And viral load is influenced by many factors, like mask wearing and social distancing.
The headline of the OP said "less lethal virus", if it was you that wrote that headline, you should change it. Viral load and viral toxicity are not necessarily the same thing. It is possible for a virus to be very dangerous, but if people avoid getting it in a large dose, it does little damage.

61. Ok to be fair, I ran what the doctor actually said in Italian through google translate
This seems to be the part that got everyone worked up in Italy:
Covid-19 "from the clinical point of view no longer exists". The San Raffaele head of Milan Alberto Zangrillo, director of intensive care, is convinced of this. Words that immediately ignited the controversy among the experts, with expressions of bewilderment and condemnation especially by the scientists who are part of the technical scientific committee.
It all started during the broadcast Mezz'ora in più on Raitre, when speaking of the observations on the situation of the Lombardy Region, Zangrillo said: "I really laugh. Today is May 31st and about a month ago we heard epidemiologists say they fear a new wave at the end of the month / beginning of June and who knows how many intensive care places there would have been. In reality, the virus practically no longer exists from a clinical point of view... ...The swabs performed in the last 10 days have a viral load from the quantitative point of view (are) absolutely infinitesimal compared to those performed on patients of a month, two months ago." It could be the American press took the liberty of inserting the "much less lethal" part in there, but I'm not fluent in Italian so can't be sure. Still, his claims were quite extraordinary and were met with rightful skepticism by his colleagues in Italy. For those fortunate enough to be fluent in Italian, this was the original text: Il Covid-19 "dal punto di vista clinico non esiste più". Ne è convinto il primario del San Raffaele di Milano Alberto Zangrillo, direttore della terapia intensiva. Parole che hanno immediatamente infiammato la polemica tra gli esperti, con espressioni di sconcerto e di condanna soprattutto da parte degli scienziati che fanno parte del comitato tecnico scientifico. |

that the 1918 virus did mutate into a less lethal strain, or we got better at treating the symptoms.
Now, this article is not saying the virus mutated - just that two physicians see a lesser viral load from swabs. And, to reiterate (not to you, but others) the government is still urging caution, social distancing, and masks for all. |

46. There are two paths the virus can take.
Remain as lethal or more lethal, but develop a longer incubation period so that lots of people get infected, the 1918 virus seemed to have taken that route, it only vanished once it had killed a shitload of people and other people started seriously wearing masks. The second path is to simply become less lethal, while becoming more contagious. We don't know which route SARS-COV-2 will take yet.

51. That's one theory
but another holds that Spanish flu rapidly evolved into a much less deadly disease after the peak of the last wave.
I'm not sure that a vaccine has ever been able to stop a pandemic in all of history. Vaccines are really great at ending diseases that are chronic to civilizations. Polio, smallpox, measles, etc. They are helpful with reducing the severity of seasonal viruses like flu, but they haven't been able to stop them or even come close. We've never had a coronavirus vaccine, so hard to say what that will do. However, I don't believe any pandemic from a novel virus has ever been brought under control by a vaccine. Instead they burn themselves out either because the virus evolves into a less deadly version and deadlier strains are less able to spread because of killing hosts, people take steps to reduce the spread by distancing, or a combination of both. I'm kind of leaning toward expecting that to happen again this time. We will develop a vaccine, but it will come as the virus is already waning or the pandemic will come to and end before a vaccine is finished. I don't expect a vaccine to be completed before the end of this year, maybe by this time next year. |

29. What exactly is this supposed to be saying?
That humans now getting the virus have an inherently stronger immune response to the virus- for some reason (which doesn't make sense at all)? Or that the isolation measures they've taken have- temporarily- slowed the virus' spread and, also, its strength inside the human body?

31. My read and understanding
is that the swabs are detecting a less deadly viral load. Doesn’t address mutation, doesn’t address any sort of immunity which I think would be way too soon. It is the observation of two doctors, with the warning from Italian officials that we all should continue to be cautious worldwide.

Those with weaker strains live longer and spread it more. Same happened to the 1918 flu virus. It eventually selected out to a much less lethal form. |

49. Wow, that's interesting (and sad).
This article doesn't address mutation - and I have no idea how long it takes for a virus to mutate, do you?

52. That all depends on the virus.
Some mutate faster like influenza, some hardly do at all.

50. Well, I don't know what's going on in Italy,
but the virus seems to be working just fine in the US. We have cases going up in many states.

53. Yes, we do
We're going to explode in the US in the coming weeks with everything opening, no social distancing, masks, etc.

56. Our cases in my small country are rising as well.
The death rate during this rise has not changed. I don’t know why.

60. I hope so! 🤞
I guess we'll see within 14 days if the protesters or looters end up deathly ill.

67. Coronaviruses commonly and easily recombine with each other
Links
https://jvi.asm.org/content/57/3/729.short https://jvi.asm.org/content/66/10/6117.short https://www.sciencedirect.com/science/article/pii/004268229190795D In this paper we report the development of a recombination assay for coronavirus, using polymerase chain reaction, in the absence of selection pressure. Our results showed that within a 1-kb region of the peplomer gene, RNA recombination occurred at almost every potential crossover site. Thus, coronavirus RNA recombination appears to be more random than previously realized.
So maybe, we should be using the common cold (also a coronavirus but much less lethal) to fight this one |

69. Maybe that's what's happening.
Viruses do seem to evolve to become less lethal to their hosts over time. After all, viruses that kill too many of their hosts also kill themselves.
Maybe this is due to natural mutations, or maybe due to gene-mixing with common-cold viruses like you mentioned that cause fewer nasty symptoms. I vaguely remember a news story where an epidemiologist mentioned that there were four distinct coronaviruses (not COVID-19) that we catch and spread around regularly - when we catch those bugs, we just call them colds. This epidemiologist theorizes that eventually, COVID-19 will become the fifth coronavirus common-cold virus. |

70. Less viral load because people are distancing and wearing masks?
Just like ending stay at home orders because the rate of infection is going down. Well duh, cause we're staying home. Less viral load today, is it because it's becoming less contagious as this Italian implies or because there are fewer opportunities for infection? Time will tell I guess.
