New Zealand Reinstates Coronavirus Restrictions After First Locally-Transmitted Case in 102 Days (cnn.com) 229

schwit1 shares a report: New Zealand has reintroduced coronavirus restrictions in parts of the country after new locally transmitted cases broke the 102-day streak the country had gone without recording a local infection. New Zealand's Prime Minister Jacinda Ardern confirmed four new locally transmitted coronavirus cases on Tuesday night, and announced that New Zealand's most populous city, Auckland, will temporarily see level three restrictions introduced for three days starting from midday on Wednesday. All four of the cases were found within one household in South Auckland according to New Zealand's Director-General of Health Dr Ashley Bloomfield. He added that none of the new cases had recently traveled outside of New Zealand. "We have been preparing for that time, and that time is now," said Dr Bloomfield adding that the "health system is well prepared." "In line with our precautionary approach we will be asking Aucklanders to take swift actions with us, as of 12 noon tomorrow, Wednesday August 12, we will be moving Auckland to level 3 restrictions," said Ardern.

    This strongly suggests that we'll never be rid of COVID-19. The article notes that the person hadn't traveled and wasn't known to be in contact with someone who did. That means for more than 3 months COVID-19 either was in one infectious individual with no symptoms, or more likely, was still spreading unnoticed among the populace.

    One person got symptoms, got tested, and suddenly we find that 3 of their family members are asymptomatic. That suggests a much higher percentage of asymptomatic spreaders than anyone has really been suggesting, as far as I'm aware.

    Three months of spreading without anyone showing symptoms is a long damn time. It suggests that once we go back to some sort of normal that we'll definitely have pockets popping up regularly. That's going to make mass gatherings, whether for school, entertainment, or business less enticing for a lot of people. That in turn hinders a return to some normalcy.

    God is this pandemic depressing.

      These are all hypotheses at this point. New Zealand is shutting down Auckland to collect data. I suspect we will have answers in a couple of days.
    • suddenly we find that 3 of their family members are asymptomatic

      You know that how? Has a sufficient amount of time elapsed to conclude they weren't pre-symptomatic? How long ago did this testing happen?

      and treatments. That said, we won't be rid of pandemics until we stop under funding public health initiatives. And not just the obvious stuff like vaccine research (which was well underway during the SARs outbreak and then we slashed the funding as soon as we got a break) but also things like cleaning up the wet markets, providing universal healthcare so people don't skip doctor's visits, providing paid sick leave to everyone so they don't show up to work sick, providing child care benefits so people don't send sick kids to school, etc, etc.

      Bottom line, we can stop pandemics, but it means some very large changes to how we run our society. And there are a lot of people who just plain don't want to do that. They'd rather live with the pandemics and the deaths and the lingering side effects.
      • There are always going to be novel pathogens. Evolution is a thing; viruses and bacteria continue to evolve, develop novel traits, and continue to propagate. Eventually they burn themselves out, but what we can choose to do is to take measures that make getting from Point A to Point C less damaging overall, by trying to suppress Point B.

        Just because we've built a world of concrete skyscrapers, a sort of psychological wall against nature, doesn't mean we aren't still part of the natural world. When you think

        • just that we can contain them before they become pandemics. But to do that we need to change how our society functions. We can't just leave everything up to the "Invisible Hand" and hope God or profit motive sorts it all out.

          Vaccines, for example, are surprisingly unprofitable, and as mentioned a whole lot of research was done on general purpose vaccines going into the SARs pandemic and then dropped like a bad habit as soon as the panic stopped.

    • Thinking about this some more, if it holds up that it was out there spreading and only after 3 months did a case get symptomatic enough for someone to go to the hospital, I bet this thing has been around for a lot longer than anyone is suspecting.

      If one person got sick enough to go see a doctor in January of 2019, nobody would have even considered that it was a new disease. It doesn't matter what country they were in. And if another showed up in March or April of 2019, even the same doctor wouldn't likely m

        It seems to me that a disease that spreads silently for several months but suddenly causes an influx of so many severe cases that it overwhelms hospitals are two diametrically opposed concepts. The only way I see it working is if people are pre-symptomatic for several weeks. Perhaps 14 days of quarantine isn't long enough.

        It's all speculation at this point. We have to wait for the data before we jump to any conclusions.

          So you don't understand exponential growth?

          It's all a numbers game. Lets suppose 1 in 100 get sick enough to go to the hospital, and you double cases every week. When you hit 1,000 people with this, only 10 are going to the hospital. A month later you're looking at 80, and the month after that 1,280. Spread 10 people over a month going to the hospital and mix them with all of the other people in there for all the other reasons, and I bet they're pretty much invisible. Send 300+ people to the hospital with t

            1. In the early days of COVID, doctors in Wuhan didn't know what COVD-19 was. Of course most went undetected!
            2. New Zealand knows what they are looking for, and are much more vigilant.
            3. 1% getting sick enough to go to the hospital seems like a massive underestimate, and is off by an order of magnitude vs. the paper you cite.
            4. Exponential growth with the rates you are spouting means there should be close to 200 people going to hospitals in New Zealand with COVID-19. We have evidence of one.

      • Honestly, I'll wager it was probably making the rounds last fall, but like anything that functions on a logarithmic growth scale, it takes time to build up critical mass. Let's imagine the virus first started making the rounds in Wuhan in early December (might have been earlier, but we don't know). That means there symptomatic carriers early on, but that because it behaves to some extent, at least in the early infection, like any number of more typical contagious diseases, no one would have thought any more

        It's not until masses of people start having symptoms that anyone would notice. That could mean we've been missing cases for a year or more.

        Seems iffy. Because we've also seen that when this thing hits a concentration of vulnerable folks like in an old age home, it's not something anyone can miss.

        • So NZ doesn't have old age homes? Or did they somehow lock them down so hard the last 3 months that nobody carrying this got in?

          Those seem to be the only explanations for how this could lurk silently among the population given your position.

    • The odds of it spreading asymptomatically for 3 months seem astronomical. We know some people are asymptomatic. However, if 50% of people are asymptomatic, and spread to one other person every 5 days, that would be like flipping a coin 20 times in a row and coming up heads. (A 0.0001% chance of happening BTW)

      I think it's far more likely someone snuck into the country undetected. There may have been a few asymptomatic cases from that person until this one now. However, 3 months in a row of asymptomatic

      People are still coming into NZ from outside the country. So it's much more likely that a quarantine was ineffective than that there was still a smoldering infection somewhere on the islands

        Yes, I don't understand how so many people are convinced COVID-19 spreading unnoticed for 3 months is the most logical conclusion.

    The New Zealand government has been very open, and has more success containing COVID-19 than any other nation. I suspect the end of the investigation will yield new or interesting information about COVID-19 transmission.

    P.S. The official government briefing on the case can be found here. [beehive.govt.nz]
    • The New Zealand government has been very open, and has more success containing COVID-19 than any other nation.

      While New Zealand has done relatively well compared to most other countries in the world, several other countries have been more successful.
        For example, Taiwan has a cumulative per capita death rate 15x lower than New Zealand, also without shutting down the economy.

      • Yes, Taiwan has been more successful than New Zealand. After posting I discovered New Zealand's clam as "most successful" is self proclaimed. However, we need to be careful that some authoritarian countries may be manipulating the data. I don't feel this is a concern for either New Zealand or Taiwan.

    ... were tempting fate. Cases will randomly continue to slip past any system. What matters is that you demonstrate the ability to stamp them out. We had an outbreak here recently, for example [covid.is], 20 days after our last one's last local transmission. Looks like it's getting back under control - but of course one doesn't want to speak too soon.

    It's not entirely clear how the current outbreak got into the country. The last one was some Romanian burglars who came to the country, were supposed to be quarantined, but immediately broke quarantine to go rob some flats. There were no "unknown source" community transmission cases there, however, so it wasn't a serious threat. Our current outbreak was more problematic as genetic studies showed two people who didn't know each other had somehow acquired virtually identical strains, one tracing back to the other, meaning that there was an unknown infected go-between. So we've had to tighten regulations - max gathering size down from 500 to 100, business enforcement on social distancing, masks on buses for the first time, etc. And of course back to much higher testing rates, both of suspected cases, as well as random sampling the population to see how common the disease actually is and to catch latent pockets.

    • They knew they were tempting fate. In fact, they knew this day would come. Regulations are already tightened. They're as prepared as one can be, as they've had the benefit of watching other's mistakes.

      The landmark "doesn't lessen any of the risk" of another spike in infections, Ms Ardern said. "One hundred days is a milestone to mark but, again, we still need to be vigilant regardless," she added.

      BBC [bbc.com]

    • What’s concerning to me is all the cases lately of transmission where the vector is unknown. With coronavirus looking like it might be prone to spread by animals [nature.com] we need to know for sure as this will drastically change evidence based responses. At least two cases have come from mink already.
    • of "Romanian Burglars" I think they'll be Ok.

      Here in America our contact tracing consists of tracing contacts between Mr Idano & Weedlord Bonerhitler and a school board in Georgia who, I shit you not, proposed moving kids around the class every 14 minutes to bypass a policy requiring them to contact parents when their kid sat next to a positive case for > 15 minutes.
  • The detection is in south Auckland which is where the primary airport for managing international quarantining is located. Which makes it the most likely area of where reintroduction will come from.

No spitting on the Bus! Thank you, The Mgt.
