    1. Maryanne Garry 🐑🇳🇿. (2020, December 12). A person with the virus who, say, has lunch with friends is a witness to an event in which the virus was possibly transmitted, and a suspect who might have transmitted it to others.

    1. UK is with EU. (2021, January 18). ..The reason we are in this third lockdown is because of the anti lockdowners like Lord Sumption ..We are going in circles, countries who have done well controlled the virus and now have an economic recovery ..And every life matters #GMB @devisridhar speaking truth to power https://t.co/U3BBV0uUSb [Tweet]. @ukiswitheu. https://twitter.com/ukiswitheu/status/1351089812799950850

    1. Kit Yates. (2021, January 22). Is this lockdown 3.0 as tough as lockdown 1? Here are a few pieces of data from the @IndependentSage briefing which suggest that despite tackling a much more transmissible virus, lockdown is less strict, which might explain why we are only just keeping on top of cases.

    1. Erik Angner. (2021, February 17). One point that the pandemic has brought home to me is just how narrow people’s expertise is. I’m regularly surprised by how a celebrated professor of X can exhibit a sub-college-level understanding of Y, even when X and Y are related. /1 [Tweet]. @ErikAngner. https://twitter.com/ErikAngner/status/1362006859004141570

    1. If you get a positive PCR test and you want to be sure that what you’re finding is a true positive, then you have to perform a viral culture. What this means is that you take the sample, add it to respiratory cells in a petri dish, and see if you can get those cells to start producing new virus particles. If they do, then you know you have a true positive result. For this reason, viral culture is considered the “gold standard” method for diagnosis of viral infections. However, this method is rarely used in clinical practice, which means that in reality, a diagnosis is often made based entirely on the PCR test.

      [[Z: A positive PCR should be followed by a viral culture test to see if you're dealing with a live infection]]

      After a positive PCR test, you don't know if the virus is alive or not. To find this out you can add it to respiratory cells (in the case of a respiratory virus) and see if they start producing virus particles).

      [[Z: Viral culture tests are rarely used in clinical practice]]

      Positive diagnoses of COVID-19 are done base on PCR only.

    1. This nasty, mysterious virus will require us all to change our minds as scientists learn more, and we may have to give up some practices and beliefs about it that we now feel sure of.

      This virus has corrupted many people mentally and many people physicall.

      • Makalah ini membahas aspek yang belum pernah dibahas sebelumnya, walaupun fragmen-fragmen isu ini sudah ditampilkan di berbagai media sejak masa awal Indonesia menangani virus ini secara serius.

      • Menampilkan milestone di sini ide yang baik. Saran saja untuk juga menampilkannya dalam bentuk visual.

    1. Research on enveloped virus presence and fate in water is hindered by the lack of proven detection methods. Detecting and quantifying viruses in environmental samples requires first concentrating the viruses in the sample into a smaller volume to improve detection limits
    1. The 1MDS-method and the HA-method did not provide as high recovery yields of the virions as the Mg-method.

      The reason for this could be the beef extract used to elute the virions from both these membranes. The other two successful methods (Mg and Al) used H2SO4 for elution.

    1. a defined quantity of a nonhuman control virus (seal herpes virus [SHV], kindly provided by H. G. M. Niesters, University of Rotterdam, The Netherlands) was spiked into each sample prior to DNA and RNA extraction. Since constant DNA quantities of the control virus are coextracted even when RNA isolation kits are used (H. G. M. Niesters, personal communication; our own unpublished observations), the virus can also serve as a control in RNA virus detection assays.
