New Coronavirus Cases Fall By 20% (axios.com) 194

Coronavirus infections continue to plummet across the U.S. From a report: The U.S. averaged about 30,000 cases per day over the past week. The progress is happening remarkably fast, and across the board. It was just last week that average daily cases dropped below 40,000, for the first time in months. This week's figures are a 20% improvement over last week. 39 states saw their caseloads improve over the past week. Alabama showed an increase in new cases, although the state had some unusual reporting glitches this week. Technically, cases also increased in Washington, D.C., but it's no cause for alarm: The District has fewer new cases per day (about 48, on average) than any state.

    Who would have guessed getting people vaccinated and still wearing masks could have such a dramatic effect on cases? It's almost as if science told us this would happen but some still refuse to believe it.

        I believe it is immunity due to prior infection as well. Early estimates suggested the true number of infected could be as high as 10x of what was recorded. For instance my entire family was sick but only one of my siblings went to get tested.

          Yes, early estimates were that actual infections could be 10x what was reported, but by May of 2020 or so, testing had kicked in to where anyone that wanted to get tested could, so the numbers were much closer to reality. The number of actual cases in NY, NJ, MA, and WA were probably much higher, but the rest of the nation where it didn't hit hard early on are probably pretty accurate.

            In October last year, I want to get a test and I could get a test, but I had to book in advance and the earliest appointments were 7 days away. I didn't bother since 7 days away made it pretty much pointless.

            • Pretty much this. I also got sick late October, I wanted to get tested but could not. The closest testing site was over twenty minutes away, and this is in a busy area in the suburbs of Chicago. They also specifically said, if you are showing symptoms, don't show up. So my only real option was to go to the hospital, and as sick as I was, I didn't want to burden them with my presence in case someone truly sick needed care.

          The testing and reporting rate in the US is still very low. CDC estimates total infections 4-5 times higher than reported, which is insane in a developed country. So over 100 million infections, but still nowhere close to herd immunity. At least the US is among world leaders in the vaccine rollout. Get those vaccines!

          It has been shown, though, that immunity from vaccines is more directed at the harder-to-mutate spike protein, including the most important part of the spike that attaches to the ACE-2 receptor, whereas immunity from natural infection is often to the more variable parts of the virus. So getting vaccinated helps even if you've been previously infected.

        Of course it is playing a big role. The CDC's COVID diseases burden" figure for the US -- the number of people estimated infected including those not reported -- is 114 million. The number of Americans who've been vaccinated is just a little more than this: 125 million. So as of today, natural and vaccinated immunity are playing a roughly equal role in slowing the spread of COVID in the US.

        In another nice round number coincidence, the 125 + 114 = 239, which given that the US population is about 329 million, means there's about 90 million Americans still fully susceptible to COVID. There is still room for COVID to do a lot of harm, but it's clearly an uphill struggle for the virus when only 27% of the population is susceptible.

        Without vaccination 2/3 of the population would be susceptible, not less than 1/3. So vaccination is a huge success.

          There is a place where antibody tests have been done. The California prison system had a failed infection control program which left a lot of people with antibodies and a successful vaccination program that left a lot more people with antibodies.

          They know, because they checked, that 75% of their population tested positive for SARS COV 2 antibodies.

          And when they got to that level, their case load dropped 98%,

            Somewhere around 60% of adults have gotten at least one vaccine. If we for the moment pretend that people under 16 don't exist (this isn't a great assumption, to be fair), that gives you somewhere in the neighborhood of 15% of people who have gotten sick with COVID.

            Doing some quick math, that would be about 49.23 million actual cases, versus about 33.1M actual cases, for an actual multiplier of about 1.49x. Hey, that's pretty much exactly in line with my prediction in another post a few minutes ago. :-)

            I think that number is way too high. Over 60% of adults have gotten at least one shot. The folks with one shot aren't fully immune, but are much, much less likely to get it, as are the 48 million people under the age of 12.

      Only the people thinking the masks are THAT effective (the types and ways people are using them). And they are not. Mask usage had not changed. What changed was vaccination. The drop was overwhelmingly due to vaccinations (and to a smaller extent, more people having obtained natural immunity during the period).

Then it went down when it cooled down in the fall, and then really took off when winter started and people went back inside.

          The island thing does make strong quarantines easier to monitor. And when fewer people are flying in general, yields smaller number of possible infection sources. I suspect there are fewer business flights per million population from other countries to New Zealand than to the US or the UK but can't be bothered to try to find any statistics for that. Much more tourism oriented I suspect. The UK does have the tunnel connecting it to the mainland along with numerous other ship based points of entry in addition to the travel by air problems everyone had. Much more connected than New Zealand - the whole EU thing - even though that's winding down. I also don't think of NZ as a site where many refugees settle and refugees moving around and living in camps don't help anything.

          The US just isn't really set up to handle federal level authoritarian control and the ____ in office didn't want to rock any boats or lose any potential votes to even try to do anything meaningful probably due to a disdain for reading and science and a reliance on a news as a source of information. Cutting off flights to a only a few spots in a pandemic was monumentally stupid. But without limiting internal travel and mandating mask wearing across the US we were doomed. India was doomed due to huge population densities and Brazil had similar problems with population densities in some areas. I'll leave it to local folks to comment on their own leaders responses to the crisis.

I get it, a vaccine that came out in record time is bound to raise eyebrows. However, these mRNA vaccines are something new and they represent one of many new technologies on the horizon that will change medicine forever. And just like people were hesitant of the automobile when it first came out, I don't blame folks for being hesitant on this. I got vaccinated, and I was kinda of excited to get an mRNA vaccine. Ever since the discovery of methylation of RNA as a means to bypass inflammation response in 2005, I've been excited at how this has paved the way for viable mRNA vaccines.

    I get it that it doesn't sound right to be able to make vaccines so quickly, but this technology is just in its infancy. There does exist a path to a day when vaccines can be produced in months timescale rather than years and be known to be safe in the majority of the cases, and that to me is what is so exciting. We're not there by any stretch, but this is a first step in that direction. Those who went out and got vaccinated, this case fall is because of you. And I think that those people deserve a pat on the back for being so willing to be vaccinated. And those who haven't been vaccinated yet, like I said, I understand. I personally couldn't fault you for not going right away.

      Some of the things I found as I researched the vaccine before letting it into my body:
      o The virus research started with SARS Classic in 2003
      o Cancer research has been collecting data on injecting humans with mRNA vaccines for many years
      o The teardown report on the Pfizer vaccine at berthub.eu looked to me like the end product of long and careful development.
      o If anything goes wrong after a vaccination, it happens in days or weeks.
      o The speed came from risking money doing one step before knowing that the one before worked, and adding money to recruit and manage more Phase III subjects so that the statistics would ramp up faster.
