• The COVID States Project #12: Executive approval update -
  The August wave of our COVID States survey indicates a continued gradual decline in approval of governors’ management of COVID-19, and a small improvement in President Trump’s management of COVID-19. The average governor saw their approval slip another 3 points in the last month, to 48% approval (versus 63% in late April). President Trump, who started from a much lower point, rebounded slightly from his low point of approval of 32% in July to 34% in August. See Figure 1 and Table 1 for trends in approval for governors by state, and Figure 1 and Table 2 for trends in approval for President Trump. The governors of Maryland, Massachusetts, and Connecticut are all at 65% approval or above. States with governors that have notably low approval ratings (below 40%) include Arizona, Florida, Georgia, Iowa, Hawaii, Idaho, Mississippi, Oregon, Oklahoma, Missouri, South Carolina, and Texas. Governors who have suffered particularly precipitous drops in the last month include the governors of California (Newsom), Virginia (Northam), and Florida (DeSantis). Newsom dropped from 58% approval to 47%, Northam from 59% to 46%, and DeSantis from an already low 40% to 29%. Notably, despite the general stability in presidential approval, Trump’s approval in Florida of his management of COVID-19 also dropped sharply, from 39% to 29%.

• The COVID States Project #14: Misinformation and vaccine acceptance -
  Scholars and public health officials have expressed growing alarm over what some have termed a “misinfodemic” − a parallel epidemic of misinformation − around COVID-19. Indeed, conspiracy theories, from the Plandemic pseudo-documentary to QAnon, fuel rising skepticism about scientific facts across many areas of public life, and in recent months especially with respect to COVID-19. Misperceptions, which can rapidly spread from obscurity to mass exposure via social media, may have the capacity to hinder the efficacy of public health efforts aimed at slowing the spread of the pandemic. Especially concerning, encountering false claims online may ultimately reduce the willingness of some Americans to get a COVID-19 vaccine when it becomes available. In this report, we assess respondents’ acceptance of 11 false claims that have circulated online since the beginning of the pandemic. The statements we use include six false claims about conspiracies or risk factors and five false purported preventive treatments for COVID-19. For the conspiracies/risk factors, we asked respondents whether or not they thought each claim was accurate, or whether they were unsure about its accuracy. For the false preventive treatments, we asked participants whether or not they believed the purported treatment was effective, or whether they were unsure about its efficacy. Here, we explore some of the factors associated with higher or lower likelihood of believing false claims. We then consider the association between believing false information about COVID-19 and vaccine acceptance.

• The COVID States Project #18: Fake news on Twitter -
  Social media acts as a conduit for fake news websites, where we define fake news as information that mirrors legitimate news in form, but “lacks the news media’s editorial norms and processes for ensuring the accuracy and credibility of information.”4 During the 2016 election, for example, many researchers and journalists alike failed to track the weaponization of misinformation on social media, leaving them to retroactively discover which demographics had been most active in sharing fake news after the election had taken place. It is important to understand in real time which parts of the population are sharing fake news on Twitter. The COVID-19 pandemic has been a once-in-a-generation disruption for Americans. According to the CDC, by October 2020, there were over 8 million cases of COVID-19 and over 200,000 deaths.5 The consequences for Americans have been wide-ranging, from coping with staggering numbers of illnesses and deaths, to restrictions on freedom of movement, to mass unemployment and economic crisis. There has been a great deal of confusion and misinformation surrounding COVID-19 − a so-called Infodemic6 − with much of it occurring online. The BBC documented the direct costs of COVID-19 misinformation, which include alcohol and cleaning product poisonings, assault, property damage and heightened racism.7 In our panel, between January 1st and September 30th, 2020, the vast majority of shared URLs from COVID-19 tweets are either from known, reputable domains (60%), or domains with unknown quality (38.9%). URLs from domains that publish fake news only comprise 1.1% of the URLs from COVID-19 tweets. However, this is likely an underestimate because if we include web domains rated as “orange” in our fake news classification system, the percentage of shared fake news URLs increases to 1.8%.

• The COVID States Project #20: Public opinion around federal and state reactions to COVID-19 -
  In every month, April through October of 2020, we surveyed individuals in every state about how federal and state governments are reacting to the pandemic. We found a remarkably consistent picture of public opinion: respondents prefer state governments over the federal government when it comes to COVID-19. Out of 8 waves in 50 states & DC − a total of 408 surveys at the state level − in 402 state-level surveys more people in the state felt the state government was reacting “about right” to the COVID-19 outbreak as compared to the federal government; and only 6 times did people in a state choose the federal government over their state government.

• The COVID States Project #22: Executive approval update -
  Despite the headwinds confronting the country in facing COVID-19, approval of most governors’ and President Trump’s COVID-19 response did not change greatly between September and October in our survey. President Trump’s approval has ticked up a point to 35%, which is still problematically low approval for the most salient issue in the 2020 election by far (in 49 out of 50 states, Alaska being the one exception, COVID-19 is ranked as ”the most important problem”). More generally, after suffering a decline in the spring, the President’s approval rating has been flatline around his October rating of 35%. (For all approval ratings for the President and all of the governors, see the tables in the appendix.) To compare, governors, as a group, have seen a gradual decline in their approval ratings between late April and September; a 1 point increase from September (47%) to October (48%) marks the first time they have improved, or even held steady since our initial survey wave. Despite this, approval of governors is generally higher than that of the President. In 42 states, the governor has a higher approval level than the President, and in 2 states the levels are the same; in 6 states, the President has a higher approval level, but in no state does the approval of the President exceed that of the governor by more than the margin of error for the survey in that state.1 Per-state approval of the President roughly tracks partisanship of the state, and the only state where his approval is above 50% is Alabama. In most of the 10 swing states, the President hovers around 35%, from a low of 29% in New Hampshire to a high of 42% in Ohio. Alaska and Iowa stand out as states that he won handily in 2016, but now finds very low approval – 34% and 32%, respectively. Other states he won in 2016 and now lingers at the national average or below are Michigan and Wisconsin. Pennsylvania –perhaps the most pivotal state in the 2020 election – runs against the trend somewhat, showing approval ratings below the national level in April, and now several points above (at 38%).

• The COVID States Project #9: Will Americans vaccinate themselves and their children against COVID-19 -
  At least 5 companies have launched Phase III clinical trials of COVID-19 vaccines, the final step before seeking approval from the U.S. Food and Drug Administration (FDA). According to NIAID director Anthony Fauci, vaccines may be widely available in the U.S. by spring 2021 if these trials are successful. But should these vaccines become available, will Americans accept them? Between July 10 and July 26, we surveyed 19,058 adults in all 50 U.S. states and the District of Columbia. We asked about the likelihood that they would seek vaccination for themselves, and for their children. We also asked about the factors that would influence their decision making. We find that, overall, 66% of adults would be somewhat or extremely likely to vaccinate themselves; 66% would be somewhat or extremely likely to vaccinate their children. These rates vary markedly between states, as shown on the figure below.

• The COVID States Project #21: Most important problems facing the nation today -
  Which issues are, or will be, on voters’ minds as they enter the voting booth on or before November 3rd? Candidates Trump and Biden have stressed quite distinct issues throughout the campaign. The Democrat, Joe Biden, has sought to maintain a focus on the President’s handling of the COVID-19 pandemic, claiming that Donald Trump is undermining Americans’ healthcare with his COVID-19 response. He also has accentuated Trump’s efforts to revoke the Affordable Care Act, and the issue of systemic racism. President Trump, the Republican, has emphasized starkly different issues, particularly law and order and the economy, while seeking to avoid focus on the COVID-19 pandemic. But to what extent are the campaigns succeeding in framing the election according to their preferred emphases? In this report, we present results from our September and October survey waves in which we asked respondents to name the most important problems (MIPs) facing the nation. We investigate overall responses, as well as differences across individual states and demographic subgroups.

• The COVID States Project #8: Failing the test -
  Rapid turnaround of testing for COVID-19 infection is essential to containing the pandemic. Ideally, test results would be available the same day. Our findings indicate that the United States is not currently performing testing with nearly enough speed. In our large (19,058 respondents) national survey, conducted between July 10 and 26, we asked whether respondents had been tested for COVID-19 and how long they had waited to get results. Our finding: 37% of those who had been tested by nasal swab received results within 2 days, and the average wait time was 4.1 days; with 31% of tests taking more than 4 days, and 10% 10 days or more. Further, there are few signs that turnaround times are diminishing. For individuals who responded that their last test had been in April, they had waited on average 4.2 days to get results; and for individuals tested in July, 4.1 days.

• The COVID States Project #5: Approval of executive performance during COVID-19 -
  The initial response to a crisis typically depends on the executive branch of government, because they may act more rapidly than legislative and judicial branches. For COVID-19 in particular, the focal decision-makers have been the president and the governors of the 50 states. In the eyes of the public, how have the president and governors responded? We surveyed 22,501 individuals across all 50 states plus the District of Columbia. The survey was conducted on 12-28 June 2020 by PureSpectrum via an online, nonprobability sample, with state-level representative quotas for race/ethnicity, age, and gender (for methodological details on the other waves, see covidstates.org). In addition to balancing on these dimensions, we reweighted our data using demographic characteristics to match the U.S. population with respect to race/ethnicity, age, gender, and education. This was the fifth in a series of surveys we have been conducting since April 2020, examining attitudes and behaviors regarding COVID-19 in the United States.

• SARS-CoV-2 infection is effectively treated and prevented by EIDD-2801 - All known recently emerged human coronaviruses probably originated in bats¹. Here we used a single experimental platform based on human lung-only mice (LoM) to demonstrate efficient in vivo replication of all recently emerged human coronaviruses (SARS-CoV, MERS-CoV and SARS-CoV-2) and two highly relevant endogenous pre-pandemic SARS-like bat coronaviruses. Virus replication in this model occurs in bona fide human lung tissue and does not require any type of adaptation of the virus or the host….

• Carrageenan containing over-the-counter nasal and oral sprays inhibit SARS-CoV-2 infection of airway epithelial cultures - Pharmaceutical interventions are urgently needed to prevent SARS-CoV-2 infection and transmission. As SARS-CoV-2 infects and spreads via the nasopharyngeal airways, we analyzed the antiviral effect of selected nasal and oral sprays on virus infection in vitro. Two nose sprays showed virucidal activity but were cytotoxic precluding further analysis in cell culture. One nasal and one mouth spray suppressed SARS-CoV-2 infection of TMPRSS2-Vero E6 cells and primary differentiated human airway…

• Aptamer Blocking Strategy Inhibits SARS-CoV-2 Virus Infection - The COVID-19 pandemic caused by SARS-CoV-2 is threating global health. Inhibiting interaction of the receptor-binding domain of SARS-CoV-2 S protein (S RBD) and human ACE2 receptor is a promising treatment strategy. However, SARS-CoV-2 neutralizing antibodies are compromised by their risk of antibody-dependent enhancement (ADE) and unfavorably large size for intranasal delivery. To avoid the limitations of neutralizing antibodies, we proposed and demonstrated an aptamer blocking strategy by…

• The in vitro antiviral activity of lactoferrin against common human coronaviruses and SARS-CoV-2 is mediated by targeting the heparan sulfate co-receptor - Coronavirus disease 2019 (COVID-19) is an ongoing pandemic that lacks effective therapeutic interventions. SARS-CoV-2 infects ACE2-expressing cells and gains cell entry through either direct plasma membrane fusion or endocytosis. Recent studies have shown that in addition to ACE2, heparan sulfate proteoglycans (HSPGs) also play an important role in SARS-CoV-2 cell attachment by serving as an attachment factor. Binding of viral spike protein to HSPGs leads to the enrichment of local concentration…

• Differentially conserved amino acid positions may reflect differences in SARS-CoV-2 and SARS-CoV behaviour - MOTIVATION: SARS-CoV-2 is a novel coronavirus currently causing a pandemic.

• Photo-catalyzed TiO(2) inactivates pathogenic viruses by attacking viral genome - Previous observations have been reported that viruses were inactivated using strong irradiation. Here, some new evidence was disclosed by studying the effects of nanosized TiO(2) on viral pathogens under a low irradiation condition (0.4 mW/cm² at UVA band) that mimics the field setting. We showed that photo-activated TiO(2) efficiently inhibits hepatitis C virus infection, and week indoor light with intensity of 0.6 mW/cm² at broad-spectrum wavelength and around 0.15 mW/cm² of UVA band also lead…

• Distinct mechanisms for TMPRSS2 expression explain organ-specific inhibition of SARS-CoV-2 infection by enzalutamide - The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly become a global public health threat. The efficacy of several repurposed drugs has been evaluated in clinical trials. Among these drugs, a second-generation antiandrogen agent, enzalutamide, was proposed because it reduces the expression of transmembrane serine protease 2 (TMPRSS2), a key component mediating SARS-CoV-2-driven entry, in prostate cancer cells….

• AT-527, a double prodrug of a guanosine nucleotide analog, is a potent inhibitor of SARS-CoV-2 in vitro and a promising oral antiviral for treatment of COVID-19 - The impact of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19, is global and unprecedented. Although remdesivir has recently been approved by the FDA to treat SARS-CoV-2 infection, no oral antiviral is available for outpatient treatment. AT-527, an orally administered double prodrug of a guanosine nucleotide analog, was previously shown to be highly efficacious and well tolerated in HCV-infected subjects. Here, we report the potent in vitro activity…

• Pharmacokinetics and pharmacodynamics of hydroxychloroquine in hospitalized patients with COVID-19 - CONCLUSION: The interindividual variability of HCQ pharmacokinetic parameters in severe COVID-19 patients was important and differed from that previously reported in non-COVID-19 patients. Loading doses of 1600mg HCQ followed by 600mg daily doses are needed to reach concentrations relevant to SARS-CoV-2 inhibition within 72hours in≥60% (95% confidence interval: 49.5-69.0%) of COVID-19 patients.
