is one reason covert 19 it has moved with such such lightning speed to our populations live viable sars co 2 is clearly being shared by people who often show no symptoms of the disease when they when they test positive for it so so we know they're playing a role in transmission much more of a role than they did for example during the sars epidemic when when patients were most infectious $5.00 to $10.00 days after they began showing symptoms the european centers for disease control say it's difficult to quantify how contagious asymptomatic people are because studies simply don't agree but the general consensus appears to be that they're less contagious than patients with symptoms or or priest symptomatic patients people who are going to get sick but just don't know it yet however there's also growing evidence that there are no significant differences in viral loads between the groups so to sum it up asymptomatic people appear to carry just as much of the virus as someone with symptoms but they seem to be at least a little less likely to spread it. and of course you can post your questions t

though those are those proteins that sars co 2 uses to attach to cells but those researchers were only working with cell cultures so so their results don't necessarily translate one to one in the real world though other studies have supported the idea that the d. 614 g. variant is more transmissible it'll take more work to find out if the mutation really does make it more infectious in us rather than just in our cells and culture . why is covert 19 considered a pandemic when less than one percent of the world's population has been infected. currently only around one person than a 1000 or so on the planet has been officially listed as a 19 case which which doesn't sound like much so i understand your confusion and and the term is a little fluid the w.h.o. which which by the way sat on the fence for weeks in the early stages of the outbreak before deciding to call covert 1000 a pandemic defines pandemic pretty simply as the world wide spread of a new disease. so all it is is an epidemic but one that spread over a number of countries or continents and is moving swiftly and affecting large

if we want to look down the road to the next potentially dangerous pathogen which which i'm like sars co 2 might easily be transmitted by mosquitoes like the light the zico virus was for example it turns out the saliva that a mosquito injects when it bites you doesn't just have a knowing effect and it doesn't just contain an anti clotting agent that keeps the blood flowing and and transmitting pathogen straight to your bloodstream that saliva also seems to give those pathogens a helping hand in sneaking past your immune system in an early critical phase of the infection so so what the work in cambodia is looking at is using proteins found in the insects alive to create a kind of universal vaccine against all of the diseases carried by mosquitoes because your immune system would react fast when it detects mosquitoes spread its super super interesting research and the early results look promising but that might help one day against a disease that's transmitted this way a lot like this week about us i don't see it having any direct benefit in covert 19 research. and that brings us to the en

they tested it in about three dozen people and those people did develop neutralizing antibodies 2 sars conteresting, those that got the experiment's vaccine were two to three times hire than the antibodies you snee people naturally infected with soft cov-2 and those who recovered. it's early and pfizer cannot prove the vaccine confers immunity to covid-19. to do that we need a much larger trial. early days, but it is some promising data. >> and u.s. government, nih and fauci, they're making all of these pharmaceutical companies share information, which i think is unprecedented, because obviously these companies want to make money and have the only cure, but they're forced to share information, share what they learn so that we all can benefit from that. right? >> that's right. and i think -- we do see some data sharing happening in science. seen it previously, but not on a scale like this, but this is a global pandemic. we need complete collectivistic not individualistic to be sure of transparency. we saw as chinese scientists shared the geno. chinese scientists sharing that data early on

so we markededly reduce the risk of transmission of sars co-v 2. >> remaining outdoors. keeping sanitizer nearby. and consider disposable utensils. >> i think the risk of transition of this virus by fomite or inanimate object is probably not the major way this is transmitted. >> reporter: won't be gathering with others this july fourth. 25% say they have no plans for celebrating. 61% say they will avoid gatherings altogether because of covid-19 concerns. and only 39% say they will be attending or hosting for the holiday. most of them in homes. >> we want to celebrate things. i get it. i've been there. i am there. but we have to think beyond that. >> reporter: as we head into the holiday weekend health experts tell us covid-19 remains a significant health threat regardless of what we're celebrating. >>> also in the peninsula in the city of san carlos is now partially reversing their decision in reopening parts of their downtown streets to cars. three blocks had been closed to give restaurants the ability to serve customers outside. it's something we've seen in many bay ar

fewer of these a 2 cells within their respiratory system that's a particular type of cell that the sars comised immune system as we do. they are less likely to get infected and legs likely to spread the virus. jedediah: i feel like we are learning something new about this virus every day. thank you for being here and guide our way through it all. thank you so much. two texas police officers killed in an n. an ambush. their chief says they never had a chance. former nypd officer dan bongino says this is why we should honor our good cops every day and guess what? he's on deck. the moment has come to deal with the denial of the promise of this nation, made to so many. ♪ because if it weren't clear before, it's clear now. this country wasn't built by wall street bankers and ceos, it was built by the great american middle class, health care workers, docs, nurses, delivery truck drivers, grocery store workers. you know we've come up with a new phrase for them: essential workers. we need to do more than praise them, we need to pay them. as president, it's my commitment to all of you, to lead on t

co-president joe derisi. we should mention joe was a key member that identified the original sars outbreak back in 2003. thank you so much for joining us. >> it's great to be here. >> before we begin, i think for all of us non-scientists out there, we have got to start with square one and understand exactly what a genome is and why it pertains to covid-19. >> sure. a genome is all the things that composes a person or a virus. >> what does that mean? that means covid-19 must also have all of these at play and what does that mean when it comes to sequencing and how many sequences have you analyzed so far? >> right. so, what we're doing here is not just testing for the coronavirus, which we do do here at the biohub in conjunction with ucsf. w sequence the genome, meaning we look at the genetic sequence. that's important because it allows us to track where the virus has been, where it mate be going next. >> and how much of this tracking have you done? because we are talking about something that is affecting every single person on this planet. and i know you have a limited team of volunteers so what have you

co-author of the study and explain the findings. we always knew that 19 had the potential to affect the brain from our experience of sars and mers and the 1st studies from china suggest about 30 percent of patients with coded 19 had neurological symptoms and what our study has done is show what these new lot of complications are so we found cases of inflammation of the brain we had patients who had strokes and the strokes are in association with clotting elsewhere in the lungs for example because the blood in copenhagen patients is very thick and sticky we also had patients who had delirium. because of the infection because of hypoxia and because of sepsis and so the impact obviously is dramatic but i would emphasize that these numbers are small considering that overall there are 11000000 people infected with 1000 with 500000 deaths the majority of patients in our study had 1000 illness of varying severity some had very mild chest disease so mad very severe disease but there were some where the neurological presentation was the 1st manifestation of 19 so i think that's important to recognize that it's not just for a spirit treat com

sars, covid-19. these all emerge from animal reservoirs. my recommendation, we amount a scientifically-based international program to survey all wild populations, understand their microbios, natural viruses that coxist with them and study them. we have the technology to do that and could easily sequence these things, produce structures if we can get ahead of the curve. we could understand the reservoirs much better than we do currently, and that would leave us more time to be ready for the next one. >> thank you. you also mentioned that there's 10 million molecules available for experimental validation. >> yes. >> are you -- you talked about the weathering, the funnel. the first funnel, is it going to be mathematic and physical rather than experimental? >> top of the funnel, of course, theoretical sense, every molecule 10 to the 60th. the drug companies and economy community have understanding of maybe 4 to 5 billion molecules of that. maybe 10 million are something i can get my hands on in a couple of weeks. of course a better chemist can make things in roughly that time frame as well. it's conceivable to create ahead of time panels that is, collections of molecules essentially frozen in the fr
