It's coming towards the end of the year, and there are still countless people minimizing the pandemic and spreading untruths So I thought I'd do a bit of a thread of FACTS about COVID-19 1/n

5/n Fact 4: most deaths that are counted as COVID-19 (at least in the US and other developed nations) have COVID-19 as the "underlying" or main cause https://jamanetwork.com/journals/jama/fullarticle/2771761 …https://gidmk.medium.com/covid-19-deaths-are-mostly-caused-by-coronavirus-2a6d2d43bd09 …

6/n Fact 5: herd immunity through natural infection is not a way out of the pandemic. It will not bring us "back to normal", and certainly not within the timeframes proposedhttps://www.researchsquare.com/article/rs-25862/v1 …

7/n Fact 6: COVID-19 is a real disease caused by the SARS-CoV-2 coronavirus. Somehow people are still questioning this (yes, really)
@MackayIM has a great piece herehttps://virologydownunder.com/sigh-yes-the-covid-virus-is-real/ …Show this thread -
8/n Fact 7: In the published data thus far, there is no large increase in suicide rates associated with lockdowns, although there are increases related to the pandemic itselfhttps://gidmk.medium.com/have-lockdowns-caused-suicides-during-covid-19-dd6b7a741f39 …

9/n Fact 8: The cost-benefit of government action against COVID-19 is COMPLEX In some situations, it may be harmful. In others, beneficialhttps://www.imf.org/en/Publications/WEO/Issues/2020/09/30/world-economic-outlook-october-2020 …

10/n Fact 9: about 20% of people who catch COVID-19 are fully asymptomatic (i.e. they never experience symptoms at all) https://jammi.utpjournals.press/doi/abs/10.3138/jammi-2020-0030 …
Show this thread -
11/n Fact 10: there is quite a lot of evidence demonstrating that people can spread COVID-19 before becoming symptomatic, with some indication that the most infectious period is right around the onset of symptomshttps://theconversation.com/covid-19-when-are-you-most-infectious-150760 …
Show this thread -
12/n Fact 11: there is some t-cell cross reactivity for SARS-CoV-2 Fact 12: this DOES NOT MEAN that we have "pre-existing immunity". From the expert:https://twitter.com/profshanecrotty/status/1293344524731691008?s=20 …

13/n Fact 13: most places in the world are far below "herd immunity" numbers We need a vaccine for community immunity!

Show this thread -
15/n Fact 15: COVID-19 is probably less deadly now than it was at the start of 2020 Fact 16: It is INCREDIBLY HARD to put a number on this differencehttps://gidmk.medium.com/is-covid-19-getting-less-lethal-f2907e06a0d …

16/n Fact 17: The cycle threshold (Ct) of PCR testing is not some magic silver bullet against a growing epidemic.
@MackayIM again has an excellent read on this herehttps://virologydownunder.com/the-false-positive-pcr-problem-is-not-a-problem/ …Show this thread -
17/n Fact 18: The comparator to government action for COVID-19 is not "business as usual", it's "widespread epidemic", and anyone who pretends otherwise is being very sillypic.twitter.com/YwGcwqWFP3
Show this thread -
18/n Fact 19: the corollary to Fact 18 is that a lot of the impact of lockdowns is UNCERTAIN
Show this thread -
19/n Fact 20: Lockdowns clearly reduce COVID-19 case numbers in the short term. Other government actions can clearly limit case numbers in the long term. There are now numerous exampleshttps://www.devex.com/news/behind-vietnam-s-covid-19-success-story-98257 …
Show this thread -
20/n (Whether this means that lockdowns "work" depends on your definition of "work" and "lockdowns", but in general it seems fair to say that COVID-19 can clearly be controlled through coordinated government responses)

21/n Fact 21: COVID-19 is the third leading cause of death for 2020 in the United States In the last few months of the year, it may have overtaken other causes of death to become THE LEADING CAUSE OF DEATH FOR >30 year oldshttps://jamanetwork.com/journals/jama/fullarticle/2774465 …

22/n Fact 22: We still do not fully know the long-term chronic impacts of COVID-19, but they are likely to impact a non-trivial portion of the people who get the diseasehttps://www.nature.com/articles/d41586-020-02598-6 …
Show this thread -
23/n Fact 23: This is something of a repetition of Fact 4, but just to clarify that the evidence is clear that most people who are classified as having died of COVID-19 did indeed die of the diseasehttps://twitter.com/GidMK/status/1341175635700457472?s=20 …

24/n Fact 24: Another corollary, this time to Facts 9 and 10 - since many people are asymptomatic when testing positive (even though the majority will go on to develop symptoms) isolating PCR+ cases is simply good public health policy

25/n Fact 25: opioid-related mortality has been rising in the US for some time, and while it may have been exacerbated due to the pandemic it is inaccurate to ascribe all overdoses to lockdowns/COVID-19https://www.cdc.gov/media/releases/2020/p1218-overdose-deaths-covid-19.html …
Show this thread -
26/n Fact 26: While COVID-19 deaths only made up 40% of all excess deaths in young people in the U.S., it is likely that this is due to undercapture of the COVID-19 burden in this population (i.e. much of the remaining 60% is COVID-19 related as well) https://jamanetwork.com/journals/jama/fullarticle/2774445 …pic.twitter.com/2qS98xCpOM

27/n Fact 27: Much of the economic and social disruption that people have experienced this year is due to THE PANDEMIC ITSELF and not necessarily government action
