Seattle's Patient Zero Spread Coronavirus Despite Ebola-Style Lockdown (bloomberg.com) 139

First known U.S. case offers lessons in how and how not to fight the outbreak. From a report: The man who would become Patient Zero for the new coronavirus outbreak in the U.S. appeared to do everything right. He arrived Jan. 19 at an urgent-care clinic in a suburb north of Seattle with a slightly elevated temperature and a cough he'd developed soon after returning four days earlier from a visit with family in Wuhan, China. The 35-year-old had seen a U.S. Centers for Disease Control and Prevention alert about the virus and decided to get checked. He put on a mask in the waiting room. After learning about his travel, the clinic drew blood and called state and county health officials, who hustled the sample onto an overnight flight to the CDC lab in Atlanta. The patient was told to stay in isolation at home, and health officials checked on him the next morning.

The test came back positive that afternoon, Jan. 20, the first confirmed case in the U.S. By 11 p.m., the patient was in a plastic-enclosed isolation gurney on his way to a biocontainment ward at Providence Regional Medical Center in Everett, Washington, a two-bed unit developed for the Ebola virus. As his condition worsened, then improved over the next several days, staff wore protective garb that included helmets and face masks. Few even entered the room; a robot equipped with a stethoscope took vitals and had a video screen for doctors to talk to him from afar. County health officials located more than 60 people who'd come in contact with him, and none developed the virus in the following weeks. By Feb. 21, he was deemed fully recovered. Somehow, someone was missed. All the careful medical detective work, it's now clear, wasn't enough to slow a virus moving faster than the world's efforts to contain it.

    I realize asymptomatic spread is not thought to be the primary means of contagion, but it is considered something which likely does happen with this virus.

      It's possible he hadn't started to shed viruses in his breath until the cough developed. Most of the strains of flu and common cold have a fixed number of days where you are actively shedding virus into the environment. These days usually start before symptoms fully develop, but not always and it's going to be a little different for everyone.

      Given the flight he was on, he might not have been the only infected person on the plane nor be the person that infected everyone else. Unless people come forward and get tested there is no way to know if they are infected. The US government can't go door to door and demand testing at gun point like China can.

        I don't know about you, but I sometimes sneeze even when I'm not sick and I don't always catch it in time to block it with some sort of fabric. If he was infected, then he would have some viruses in his respiratory tract, which would come out in a sneeze or cough. The only way to stop it is for even asymptomatic people to be wearing masks.

        Unless people come forward and get tested there is no way to know if they are infected.

        Even if they show up at the hospital, they're not going to get tested unless they have severe symptoms. There aren't enough kits to go around.

          He had been coughing for FOUR DAYS before he went in for medical care! How many people did he infect before he even got to the hospital?!? That had nothing to do with testing, flawed or otherwise.

          To be fair to him - when he was getting sick, knowledge about COVID-19 was just starting to be widely disseminated. I know that, under more typical circumstances, many doctors tell their patients to not come in for common symptoms unless they've had them for a week - the reasoning being if you've had symptoms for a week, you may very well have an opportunistic (follow-up) bacterial infection which may require antibiotics. Typical viral infections aren't treated because your body generally takes care of them just fine, and your doctor isn't going to waste antivirals on a rhinovirus anyway.

          • To be fair to him - when he was getting sick, knowledge about COVID-19 was just starting to be widely disseminated.

            Bingo. It's almost certain he didn't realize what he had and was just trying to weather what he thought was a common cold or flu.

            I mean, if you knew (or even suspected) that you had COVID-19 you wouldn't wait around for 4 days before seeing a doctor.

          Whether the tests on his close contacts was accurate is very much a factor. Close contact tracing does no good if the tests you are using to determine whether people are infected does not give correct results. It is absolutely possible that some of the 60 people tested were asymptomatic, gave negative test results, but were actually carrying the virus.

          This is shocking to you ?

          In the event you don't live in the US, it can cost you a few hundred dollars* just to walk in and SEE a physician ?
          Are you willing to shell out a few hundred dollars every time you get a cough, sniffles, etc. ?

          *Especially early in the year like this before folks satisfy their deductibles ( even with great insurance ).

          Did you know one of the primary reasons people don't take sick days is because many companies REQUIRE a
          Doctors Note indicating that you did, in fact, waste a hundred bucks or so just to obtain said note ? Did you also
          know this is by DESIGN of said companies as a deterrent to keep folks from taking any sick time they have ?

          Hell, the biggest question I have is " How much is the quarantine going to cost him in the end ? "

      If we had stocked up on masks during the previous SARS outbreak and we had a culture of wearing them like a lot of Asian countries, then we might have had a chance.

      Even if the masks were only 33% effective, that could reduce the infectivity rate (new infections per day per existing infected) from the estimated 2 down to 1.3. Over the course of 30 days, that's the difference between infecting 1 billion people and 5,000 people. If the masks were more than 50% effective, then the infectivity rate would drop be

          What perishable material are they using in these masks anyways? And why would they stock the kind of masks that expire?

          That said, even if they did expire, it's still better to have them at a reduced effectiveness than having nothing. As I calculated above, even at 33% effectiveness it would significantly slow the spread of the disease, assuming you had enough for everyone.

      Only 20% of infected won't notice not anywhere near most. Even though they won't get the disease they will still spread it.

      and a few will be the unlucky ones suffering from severe complications, some of which will die.

      If you assume 70% of the US population will be infected sooner or later this means the "few" unlucky ones suffering from severe complications is 11.4 million people.

      Nobody is suggesting every US case is related to this one. But gene sequencing has shown the Seattle area outbreak does come from this patient. The six week delay before the second confirmed patient (plus no apparent relation) suggests it has been brewing in the community undetected and we have an unknown number of active infections. Hence everybody's working from home and events are cancelled.

      Other outbreaks around the country have different sources. The first California community spread was likely from failed isolation of repatriated Americans in one of the military bases. There are others who are known to have got it while traveling to Italy or Egypt.

      Because it is not a "light flu" It has a death rate about twenty to thirty times as high as that of a "light flu".

      For people 80 or over, of five who get sick, one will die. For people 30 or over, getting this is more likely to kill than the flu is for all ages combined .

      Not only that, but (even for younger people) this is one of those diseases where having it not only doesn't keep you from catching it again, but sets you up so the next time you have it you're FAR more likely to have the bad form.

      It's far more contagious than the flu, so once it gets going in a population the exponential explosion is very much steeper. There is no vaccine. There is no effective treatment for the severe form, even to improve things slightly, that can be applied at scale. There won't be until at least next year.

      The ONLY thing that's better about it is that (so far) it only infects mammals. So migratory birds aren't crossing country boundaries and bombing populations with the contagion. Yet. There's a chance that hair-trigger tracing and quarantine can slow the transmission and perhaps reduce the overall numbers who get it before treatments are developed.

      Welcome to a plague year. We haven't had one for quite a while. We have one now.

    The article suggests that the patient himself did not need any treatment other than bed rest.

    If individuals need to pay, then they will be inclined not to be tested. Would you?

    Assuming that his symptoms were mild, was there any need to put him in hospital in the first place? Could he have been sent home with nursing care to make sure there was no need for him to leave home or interact with anyone else. Much cheaper.
