US To Require Negative COVID-19 Tests For International Air Passengers (reuters.com) 111

According to Reuters, the CDC is expected to sign an order on Tuesday requiring nearly all international air travelers to test negative for COVID-19 within 72 hours of departure. Those under 2 and passengers connecting through the UK are exempt. From the report: The new rules are to take effect two weeks from the day they are signed by CDC Director Mark Redfield, which would be Jan. 26. The CDC has been urgently pressing for an expansion of the requirements with the Trump administration for weeks. One remaining issue is how to address some countries that have limited testing capacity and how the CDC would address travel to those countries, the sources said.

At a White House meeting on Monday, Redfield again made an urgent case to adopt the testing requirements as new strains of COVID-19 are identified in different parts of the world. He raised concerns that vaccines could potentially not be effective against new strains, sources said. U.S. officials do not plan to drop restrictions that were adopted starting in March that ban most non-U.S. citizens who have been in most of Europe, the United Kingdom and Brazil as soon as possible, the sources said. They added that public health officials are sympathetic to the push to lift the restrictions that apply only to a limited number of countries.

Different parts of the world are experiencing different strains of novel coronavirus 19; the strain first discovered in the UK (now also in 3 US states) is particularly virulent. More people visit the UK and the US than African countries; more outside visitors increases risk.

          I have been cured of HCV and can tell you that having antibodies and still being at too low a level for a pcr test to pick up the presence of the virus can be a problem. I have also had my first shot of vaccine and will most likely will show a positive result with a covid antibodies test. We do not know yet at what level of infection the virus is not transmitted. The same with HCV so to ascertain whether or not I am free from HCV took over 2 years of testing below the LOC of HCV testing by pcr. I will always show positive for HCV antibodies although they may very well leveled off and not be at a high level now, 5 years after being cured with the drug Harvoni.

          The real problem with this virus is we do not know the length of human immunity or whether or not it will quickly mutate into a form that the old antibodies cannot handle. So in theory this disease may very well turn out to be a rival for the black plague if we do not do the science necessary and keep up the international vaccinations and put a great value on the institutions like the WHO and especially the shared science that helped us eradicate polio and even small pox in some places.

          Link to a pdf about pcr rna testing and what it can and cannot do. [cdc.gov]I do not know the accuracy LOC for covid by pcr testing but a positive test may or may not mean that you can spread the virus so the better safe than sorry approach is called for all who show a positive antibody test which can be done in the field without the need of expensive equipment and highly trained staff.

          Thus the quarantine requirement with positive covid 19 antibody tests. You cannot know whether or not you are infected without a positive quantitative pcr test or obvious symptoms of a chronic infection. If you test positive for the presence of the virus it can be at low levels, but you can also have a false negative occur if the infection is below the test LOC during the test.

          So the assholes that still refuse to wear masks and think that this virus will ignore them are complete jerks and need be put on body removal duties at seniors facilities, just maybe then they will get the message.

          PS. I have also worked in the field and have done body removal and I have also worked in the field transporting the living and near dead and was qualified in field emergency transport procedures. I do not suffer from delusions about how serious respiratory diseases can become. Hell even norwalk can do a re-infect cycle in care homes and take out your parents and even you if you fail to take precautions and react strongly to a norwalk infection. I can tell you from experience that it has a smell that is sickening sweet when you puke and shit until you become badly diaphoretic and need to go on saline and electrolytes. Covid 19 is much worse it slowly suffocates you by drowning if it becomes chronic, it is not a quick or pleasant way to go to say the least.

          I may very well have to go to work as I am retired but still on the call list. I am dreading having to help remove the dead and dying this time around but I am an old soldier and I will do my duty if called! I only do this as an anon because there are still Trump tards trying to cloud and obscure the truth and I do not want to become another one of their favorite targets!

            Also the vaccines are not 100% effective. Depending on the particular one you get and if it is properly administered they can be anywhere from 50% to 95% effective.

            So in the best case you still have a 1 in 20 chance of getting a disease that could have chronic, debilitating effects, assuming you survive it. And worst case is flipping a coin.

            Things won't go back to normal for a long time, certainly not this year. There are plenty of people not willing to take that risk, myself among them.

              Whoa there! You are making a huge jump to conclusions! Even without a vaccine, you only have a 1 in 5 chance of having chronic, debilitating effects. The vast majority of people have mild symptoms. Just extrapolating from these facts, you would have a 1 in 100 chance of getting chronic, debilitating effects. However, there is evidence that people that contracted COVID after getting the vaccine have a lower chance of it being severe than those that contracted COVID without the vaccine.

              Moderna produced more evidence that its vaccine can prevent severe disease. Of 30 volunteers who developed severe cases of Covid, all had received the placebo, not the vaccine.

I picked up something in California in January 2020 with symptoms now tied to COVID-19 (cough, loss of last / smell, shortness of breath, unexpected hike in blood pressure - no fever, though). By the time COVID tests and antibody tests were available to me I tested negative. Then in September I tested positive (I tested negative 2 weeks later). This is anecdotal, but meshes with reports.

        • Thing is, at ~$44 for an antibody test, and ~$20 for the vaccination, I'm going to say that if it was "PROFITS FIRST" they'd be going whole-hog for antibody testing, because that's bigger money.

          It's literally cheaper to just hit you up with the vaccine if they suspect that you're not immune to it than to test to check whether you are or not.

      It is not that effective. Other countries do this, so it is not a big deal. But the way these test work, the incubation time of the virus, means that what we are doing now, the masks, the social distancing, is still the best remedy. In the US, the problem is that we often do not observe these precaution, as we saw with out elected representatives during the recent insurrection. Many of the officials refused to wear masks while cowering from their constituents.

        It's a surprising list of countries that managed it. Of course, being an island helps a lot. But even non-island countries have managed, and it kind of shows where the country works thanks to and where the country works despite its government. In a crisis you see the real faces of friends, but also managers.

        And quite frankly, if we were rational people, then we would boot our leaders and replace them with people who can do the job. But of course, as long as they're members of the right party, that won't happen. Sad, really, how we transformed democracy into party-oligarchy.

There are exceptions for people with permanent resident status and for things like student visas. And most countries have similar restrictions (though in probably all cases far more coherent). Only someone out of touch with reality would even think that international vacation travel was a thing right now. The world is shut down.

          This is actually a great example of how the US federal government has basically ceased to function. The Trump administration put these bans in place by presidential proclamation and then seems to have just forgotten about them. Most of these places now have lower infection rates than the US, and even those that are high now had low rates for many months. The exceptions for student visas appear to have just been implemented with no specific guidance from the main part of the administration. The US government is totally on auto pilot.

    The first four days have a false negative rate of nearly 100%.

    Of course, you can also get infected literally moments after the test, meaning that you can gestate the virus for a couple days before you get on a plane.

    You should be required to have at least two negative tests spread a few days apart, or better yet, a two week quarantine before travelling. Otherwise, this is barely slowing it down.

      People's brains are binary. Negative test, no COVID. Positive test, COVID. What's that? There are false positives and negatives? Stop trying to confuse everyone with your intellectual elitism.

      I was seriously told be a clinician once that a test I was working on had to read out as positive or negative otherwise it would never be accepted.

        Well, it's testing for condition X. If it finds X, that's a positive. If X fails then the default is not-X, which is a negative for X.

        So in that regard it's perfectly reasonable. Any other outcome would be "might be X" which isn't really helpful, as you already knew that - why else test.

          I'm not sure if you were trying to demonstrate my point, but if so, thanks?

          Any observation, whether it's a medical test or measuring the position of Mercury, will have some error. If you impose a positive/negative threshold then you'll have some false positives and some false negatives. So any test, doesn't matter what it is, can only decrease the "might" in "might be X". Human brains are extremely bad at intuitively grasping this fact, and it causes a lot of problems.

            That's because it's so unintuitive that I'm struggling to follow your logic.

            X? -> unknown

            Test X -> X, !X (as appropriate)
            If Test is accurate, unknown -> X, !X
            If Test is not accurate, unknown -> wrong

            I don't understand how you think that replacing uncertainty with wrongness is decreasing the 'might'.It's explicitly making things worse.

            What you were challenging is a test that results in

            Text X -> X, !X, ??

            This adds an additional failure state, unknown -> ??

            So now we've gone from uncertainty t

              Let me give you a concrete example. Actually two (maybe three?), because there are two things going on here.

              1) US guidelines for urine opioid tests used to set a particular threshold for a positive. That threshold was rather aggressive, and there were a lot of false positives. So the threshold was raised. It's still quite possible to get a false positive by eating some poppyseed bagels the day of the test, although on a test that gives a continuous readout it's quite low. On a +/- test you get back a +. On

                It feels you'd rather provide people with the information needed to make a judgement call, rather than tell them a concrete answer. I can understand that, but

                Assume you're a regulator deciding whether to let people on a plane, and into the country with no quarantine. A negative test seems like a great criterion right? Did you take into account the false negative rate? Does anyone? There are countless studies on this, and the answer is, most people, physicians or otherwise, are very bad at taking into account things like test performance, prevalence, etc.

                While I agree they're very bad at that, I'm not sure the answer is to give them a test result that's even harder to interpret.

                "Sorry Sir, we can't let you onto the aircraft as your test result is 'sort of' and we're feeling a bit risk adverse today."

                There would be anger.

                  Regulators have to establish a decision threshold, but that's not what I'm talking about.

                  You yourself mentioned taking into account the error rates. If you do that, your "certain" answer goes back to being uncertain. That's because there is no certainty. My point is that 1) you reduce the error rate by using the raw test result and thresholding, if you're going to, only at the end of the calculation; and 2) in many circumstances it is valuable not to apply a threshold at all, and rather communicate the unce

                    Do you know what a positive routine screening mammogram means?

                    It means "Sweetheart, can you check me for lumps?"

                • People can kind of work with percentages, the problem is when they get to 50/50, or to 5/95.

                  If you take the weather as an example, you'll almost never see a 50% chance of rain, because the coin-flip nature of it makes most people confused. Meteorologists will skew the result to give you a slightly better idea of what to do.

                  But also a 5% chance of rain reads as 0% to most people, so if it rains, they're angry. So I agree with you in the sense that people can find non-exact values a bit confusing, but also, w

      The goal isn't to prevent 100% of infected people entering the country. The goal is to reduce the number of infected people entering the country.

      Where did you get this information? New Zealand has been highly successful at containing COVID-19, and they test at days 3 and 12 of managed isolation. [miq.govt.nz] From following the Health Ministry's press conferences, the majority of cases are detected on day 3. [beehive.govt.nz] (sorry, I don't know the exact date, it's more of a trend)

      Typically a PCR test can detect the disease before onset of symptoms, [nytimes.com] around the time the individual becomes contagious.

  • In a country where nearly 8% of the population has caught COVID - THEY are insisting people are testing negative. I'd be afraid of going to the US and catching COVID.
    • exactly, though I imagine this is probably intended for future situation with the hope that the US eventually gets back to normal once the Vaccine is widely distributed. better to iron out the bugs in the process now while it doesn't matter if someone infected gets through.
  • Where do you think most of the spreading COVID in the world is? I guess it's useful for a before and after. If you're negative going into the US, chances are you won't be when you leave.
    • If you talk to a random person in the US right now, there is a 0.025% chance that they have covid.

      • Random is not average. Randomly you can talk to a person who has taken no precautions and meets with many people every day or you can talk to a person who has been in a bunker for 6 weeks and can only communicate with them over Zoom.
  • This will allow aid to be freed up for urgent medical attention given to those in need of respirators, etc. It will also reboot cashflow for affected small businesses and solo professionals. And don't hesitate to lockdown again if necessary. It's working where it's in place around the world. There's only another 8-12 months of this to go - provided vaccinations reach the level needed for herd immunity. What's 12 months of common sense response to a public health disaster compared to the past four fucking

    It is insane that anyone's allowed without being tested even on a domestic flight or "if transiting through the UK"

    Are the US authorities just not serious at all about trying to mitigate the spread?

      Unfortunately not yet. But many citizens are. I haven't been indoors unmasked with anyone outside my immediate family since March. And when I am indoors masked I keep it brief.

    • Why is it insane? All the testing is completely pointless and a total waste of time, resources and money. The only people who should be getting tested are suspected cases, confirming that a confirmed case is no longer infected and the front line workers to have to knowingly come in contact with the infected. In the day or two it takes to get your test result back, you could have picked it up from any number of sources like the grocery store you stopped at 15minutes after having your test sample taken.

        No. It takes 45 minutes turnaround to get results for an antigen test. The requirement should be that the test Has been completed within the past 24 hours with results verified before being allowed to gain access to the airport.

        ... It has also been confirmed that you can be spreading it for days before a test will even pick it up as a positive result.

        None of this means that we should not require people be tested recently and regularly before

  • It's just good sane policy to prevent the spread of COVID-19 to the rest of the world by testing Americans before they get let off their island ;-)

    But seriously man most countries have had policies on this for many months already. Comically the people in the UK just discovered that as part of wanting to be independent of the EU they are now independent enough that they are getting turned around at customs if they don't have a critical reason for travelling during the pandemic, something which does not apply
