The coronavirus disease 2019 (COVID-19) pandemic in the US has been largely monitored on the basis of death certificates containing reference to COVID-19. However, prior analyses reveal that a significant fraction of excess deaths associated with the pandemic were not directly assigned to COVID-19 on the death certificate. The percent of excess deaths not assigned to COVID-19 is also known to vary across US states. However, few studies to date provide information on patterns of excess mortality and excess deaths not assigned to COVID-19 for US counties, despite the importance of this information for health policy and planning. In the present study, we develop and validate a generalized linear model of expected mortality in 2020 based on historical trends in deaths by county of residence between 2011 and 2019. We use the results of the model to generate county estimates of excess mortality and excess deaths not assigned to COVID-19 for each county in the US along with bootstrapped prediction intervals. Overall, the proportion of excess deaths assigned to COVID-19 was 81%, meaning that 19% of excess deaths were not assigned to COVID-19. The proportion assigned to COVID-19 was lower in the South (76%) and West (75%) as compared to counties in the Midwest (81%) and Northeast (94%). Across US Census Divisions, the proportion was especially low in the East South Central Division (67%). Rural counties across all divisions (67%) reported lower proportions of excess deaths assigned to COVID-19 than urban areas (83%). For instance, in the Middle Atlantic and Pacific Divisions respectively, only 47% and 39% of excess deaths were assigned to COVID-19 in nonmetro areas. In contrast, the New England Census Division stood out as the only division where directly assigned COVID-19 deaths actually exceeded excess deaths, meaning there were 1.23 directly assigned COVID-19 deaths for every 1 excess death. However, this finding did not extend to nonmetro areas within New England where only 64% of excess deaths were assigned to COVID-19. The finding that metro areas in New England reported higher direct COVID-19 mortality than excess mortality suggests that reductions in mortality from other causes of death may have occurred in these areas, at least among some populations. Across individual counties, the percentage of excess deaths not assigned to COVID-19 varied substantially, with some counties9 direct COVID-19 tallies capturing only a small fraction of total excess deaths, whereas in other counties the direct COVID-19 death rate far exceeded the number of estimated excess deaths. Taken together, our results suggest that regional inequalities in the mortality burden associated with COVID-19 are not fully revealed by data at the state level and that consideration of excess deaths across US counties is critical for a full accounting of the disparate regional effects of the pandemic on US mortality.

Abstract Background This study developed deep learning models to monitor global intention and confidence of Covid-19 vaccination in real time. Methods We collected 6.73 million English tweets regarding Covid-19 vaccination globally from January 2020 to February 2021. Fine-tuned Transformer-based deep learning models were used to classify tweets in real time as they relate to Covid-19 vaccination intention and confidence. Temporal and spatial trends were performed to map the global prevalence of Covid-19 vaccination intention and confidence, and public engagement on social media was analyzed. Findings Globally, the proportion of tweets indicating intent to accept Covid-19 vaccination declined from 64.49% on March to 39.54% on September 2020, and then began to recover, reaching 52.56% in early 2021. This recovery in vaccine acceptance was largely driven by the US and European region, whereas other regions experienced the declining trends in 2020. Intent to accept and confidence of Covid-19 vaccination were relatively high in South-East Asia, Eastern Mediterranean, and Western Pacific regions, but low in American, European, and African regions. 12.71% tweets expressed misinformation or rumors in South Korea, 14.04% expressed distrust in government in the US, and 16.16% expressed Covid-19 vaccine being unsafe in Greece, ranking first globally. Negative tweets, especially misinformation or rumors, were more engaged by twitters with fewer followers than positive tweets. Interpretation This global real-time surveillance study highlights the importance of deep learning based social media monitoring to detect emerging trends of Covid-19 vaccination intention and confidence to inform timely interventions. Funding National Natural Science Foundation of China.

<li><strong>Small area variation in crime effects of COVID-19 policies in England and Wales</strong> -
|
||
<div>
|
||
It is well established that COVID-19 policies to restrict movement induced widespread falls in many crime types internationally. Much less is known about variation between areas in how these changes occurred. This study uses k-means clustering to examine local area variation in police notifiable offences across England and Wales. It finds that crime in most areas remained stable, a small proportion of areas accounting for disproportionate change. These were typically city centers with plentiful pre-pandemic crime opportunities, dominated by theft and shoplifting offences. We explore potential implications for policy, theory and further research.

Recent research suggests that shifting users’ attention to accuracy increases the quality of news they subsequently share online. Here we help develop this initial observation into a suite of deployable interventions for practitioners. We ask (i) how prior results generalize to other approaches for prompting users to consider accuracy, and (ii) for whom these prompts are more versus less effective. In a large survey experiment examining participants’ intentions to share true and false headlines about COVID-19, we identify a variety of different accuracy prompts that successfully increase sharing discernment across a wide range of demographic subgroups while maintaining user autonomy. Research questions • There is mounting evidence that inattention to accuracy plays an important role in the spread of misinformation online. Here we examine the utility of a suite of different accuracy prompts aimed at increasing the quality of news shared by social media users. • Which approaches to shifting attention towards accuracy are most effective? • Does the effectiveness of the accuracy prompts vary based on social media user characteristics? Assessing effectiveness across subgroups is practically important for examining the generalizability of the treatments, and is theoretically important for exploring the underlying mechanism. Essay summary • Using survey experiments with N=9,070 American social media users (quota-matched to the national distribution on age, gender, ethnicity, and geographic region), we compared the effect of different treatments designed to induce people to think about accuracy when deciding what news to share. Participants received one of the treatments (or were assigned to a control condition), and then indicated how likely they would be to share a series of true and false news posts about COVID-19. • We identified three lightweight, easily-implementable approaches that each increased sharing discernment (the quality of news shared, measured as the difference in sharing probability of true versus false headlines) by roughly 50%, and a slightly more lengthy approach that increased sharing discernment by close to 100%. We also found that another approach that seemed promising ex ante (descriptive norms) was ineffective. Further-more, gender, race, partisanship, and concern about COVID-19 did not moderate effectiveness, suggesting that the accuracy prompts will be effective for a wide range of demographic subgroups. Finally, helping to illuminate the mechanism behind the effect, the prompts were more effective for participants who were more attentive, reflective, engaged with COVID-related news, concerned about accuracy, college-educated, and middle-aged. • From a practical perspective, our results suggest a menu of accuracy prompts that are effective in our experimental setting and that technology companies could consider testing on their own services.

Worldwide shortage of vaccination against SARS-CoV-2 infection while the pandemic is still uncontrolled leads many states to the dilemma whether or not to vaccinate previously infected persons. Understanding the level of protection of previous infection compared to that of vaccination is critical for policy making. We analyze an updated individual-level database of the entire population of Israel to assess the protection efficacy of both prior infection and vaccination in preventing subsequent SARS-CoV-2 infection, hospitalization with COVID-19, severe disease, and death due to COVID-19. Vaccination was highly effective with overall estimated efficacy for documented infection of 92.8% (CI: [92.6, 93.0]); hospitalization 94.2% (CI: [93.6, 94.7]); severe illness 94.4% (CI: [93.6, 95.0]); and death 93.7% (CI: [92.5, 94.7]). Similarly, the overall estimated level of protection from prior SARS-CoV-2 infection for documented infection is 94.8% (CI: [94.4, 95.1]); hospitalization 94.1% (CI: [91.9, 95.7]); and severe illness 96.4% (CI: [92.5, 98.3]). Our results question the need to vaccinate previously-infected individuals.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">
|

Background Calculations of disease burden of COVID-19 are used to allocate scarce resources and historically have focused on mortality, with little attention to morbidity such as postviral post-COVID, similar to chronic fatigue syndrome (CFS), which strikes 4 and 16% of male and female survivors. This paper quantifies post-COVID disability burden and combines it with case fatality to estimate total morbidity per COVID-19 case. Methods Healthy life years lost per COVID-19 case were computed as the sum of (incidence<em>disability weight</em>remaining lifespan) for death and post-COVID (modeled as CFS) by sex and 10-year age category. In addition to death, the main model considered lifelong mild, moderate or severe CFS; Model 2, CFS which resolved in ten years; Model 3, no CFS but 10% risk of death 10 years later. Results In all models, acute mortality was only a small share of total morbidity. For lifelong moderate CFS symptoms, healthy years lost per COVID-19 case ranged from 0.92 (male in his 30s) to 5.71 (girl under 10) and were 3.5 and 3.6 for the oldest females and males. At higher symptom severities, young people and females bore larger shares of total morbidity; if symptoms were persistent or survivors had later increased mortality, young people of both sexes were at highest risk. Conclusions Compared to post-COVID, acute mortality contributes only a small share of total COVID-19 morbidity. Total burden falls heavily on the young, who are currently deprioritized for preventive interventions such as vaccines. To fairly allocate scarce resources, decisionmakers should consider all morbidity.

Background: Distribution of mRNA-based SARS-CoV-2 vaccines to healthcare personnel (HCP) in the United States began in December 2020, with efficacy >90%. However, breakthrough infections in fully vaccinated individuals have been reported. Meanwhile, multiple SARS-CoV-2 variants of concern have emerged worldwide, including the B.1.427/B.1.429 variant first described in California. Little is known about the real-world effectiveness of the mRNA-based SARS-CoV-2 vaccines against novel variants including B.1.427/B.1.429. Methods: In this quality improvement project, post-vaccine SARS-CoV-2 cases (PVSCs) were defined as individuals with positive SARS-CoV-2 nucleic acid amplification test (NAAT) after receiving at least one dose of a SARS-CoV-2 vaccine. Chart extraction of demographic and clinical information was performed, and available specimens meeting cycle threshold value criteria were tested for L452R, N501Y and E484K mutations by RT-PCR. Results: From December 2020 to March 2021, 189 PVSCs were identified out of 22,729 healthcare personnel who received at least one dose of an mRNA-based SARS-CoV-2 vaccine. Of these, 114 (60.3%) occurred within 14 days of first vaccine dose (early post-vaccination), 49 (25.9%) within 14 days of the second vaccine dose (partially vaccinated), and 26 (13.8%) ≥14 days after the second dose (fully vaccinated). Of 115 samples available for mutation testing, 42 were positive for L452R alone, presumptive of B.1.427/B.1.429; three had N501Y mutation alone and none were found with E484K mutation. Though on univariate analysis partially- and fully-vaccinated PVSCs were more likely than early post-vaccination PVSCs to be infected with presumptive B.1.427/B.1.429, when adjusted for community prevalence of B.1.427/B.1.429 at the time of infection, partially- and fully-vaccinated PVSC did not have statistically significantly elevated risk ratios for infection with this variant (RR 1.40, 95% CI 0.81-2.43 and RR 1.13, 95% CI 0.59-2.16, respectively). Conclusions: The great majority of PVSCs occurred prior to the expected onset of full, vaccine-derived immunity. Although the B.1.427/B.1.429 variant did not represent a significantly higher proportion of PVSCs than expected, numbers were small and there was a trend towards higher representation in the partially- and fully-vaccinated subset. Continued infection control measures in the workplace and in the community including social distancing and masking, particularly in the early days post-vaccination, as well as continued variant surveillance in PVSCs, is imperative in order to anticipate and control future surges of infection.

Introduction: COVID-19 vaccine hesitancy increased among US adults April-December, 2020, and threatens efforts to end the pandemic. Among US adults 18-64 years, we report prevalence of and reasons for vaccine hesitancy, overall and by employment and occupation, during the COVID-19 vaccine rollout. Methods: The Delphi Group at Carnegie Mellon University conducted a COVID-19 survey administered by Facebook. In January, February and March 2021, 791,716, 710,529, and 732,308 Facebook users, respectively, reported age 18-64 years and answered a vaccine acceptance question. Weights matched the sample to the age, gender, and state profile of the US population. Percentages and risk ratios (RR) for vaccine hesitancy were estimated using a weighted Poisson regression; 95% confidence intervals (CI) were calculated using robust standard errors. Results: Vaccine hesitancy decreased among adults 18-64 years from January (27.5% [95%CI, 27.3-27.6]) to March (22.1% [95%CI, 21.9-22.2]). Vaccine hesitancy varied widely by occupational category: 9.6%, (95%CI, 8.5-10.7) in life/physical/social sciences to 46.4% (95%CI, 45.1-47.7) in construction/extraction. Almost half (47.9%, 95%, 47.6-48.3) of hesitant participants indicated concern about side effects, and over a third did not believe they needed the vaccine, did not trust the government, were waiting to see if it was safe, and did not trust COVID-19 vaccines (versus 14.5% [95%CI, 14.3-14.8] who did not like vaccines in general). Conclusions: In this nationally representative survey of adults 18-64 years, vaccine hesitancy decreased to 22.1% by March, 2021. Still, hesitancy, which varies widely by occupation, remains a barrier to pandemic control. Reasons for hesitancy indicate messaging about safety and addressing trust are paramount.

Appearing at the end of 2019, a novel virus (later identified as SARS-CoV-2) was characterized in the city of Wuhan in Hubei Province, China. As of the time of writing, the disease caused by this virus (known as COVID-19) has already resulted in over 3 million deaths worldwide. SARS-CoV-2 infections and deaths, however, have been highly unevenly distributed among age groups, sexes, countries, and jurisdictions over the course of the pandemic. Herein, I present a tool (the covid19.Explorer R package and web application) that has been designed to explore and analyze publicly available United States COVID-19 infection and death data from the 2020/21 U.S. SARS-CoV-2 pandemic. The analyses and visualizations that this R package and web application facilitate can help users better comprehend the geographic progress of the pandemic, the effectiveness of non-pharmaceutical interventions (such as lockdowns and other measures, which have varied widely among U.S. states), and the relative risks posed by COVID-19 to different age groups within the U.S. population. The end result is an interactive tool that will help its users develop an improved understanding of the temporal and geographic dynamics of the SARS-CoV-2 pandemic, accessible to lay people and scientists alike.

<p data-aos="fade-left" data-aos-anchor-placement="bottom-bottom">

The impact of Zinc (Zn) sufficiency/supplementation on COVID–19 mortality and infections remains unknown. During an infection, the levels of free Zinc are reduced as a part of 9nutritional immunity9 to limit the growth and replication of pathogens and ensuing inflammatory damage. However, considering its key role in immune competence and the widespread deficiency in large sections of different populations (3–54%), prophylactic and therapeutic Zn supplementation has become part of routine prescription even without any evidence for its protective role in COVID–19. Expectedly, multiple trials are ascertaining the positive effect of Zn supplementation on COVID-19 when given in combination with standard of care treatments. However, the trials9 designs seem to lack the power to identify negative effects especially in the currently identified vulnerable groups, e.g., elderly, comorbid (contributing 9 out of 10 deaths; up to >8000–fold higher mortality). When we analyze the COVID–19 data from 23 socially similar European populations with supposedly comparable confounders (population: 522.47 million; experiencing up to >150 fold difference in death rates) and at the matching stage of the pandemic (12 March – 26 June 2020; 1st wave of infections), the populations′ Zn-sufficiency status is found consistently positively correlated with COVID-19 mortality (r(23): 0.7893–0.6849, p-value<0.0003) and infections [r(23):0.8084 – 0.5658; p-value<0.005]. The observed association is contrary to what would be expected if Zn sufficiency was being protective in COVID-19. Thus, controlled trials or retrospective analysis of the adverse event patients′ data seem warranted to correctly guide the practice of Zn supplementation in COVID-19.

Background As of April 19, all adults aged 16 years and older are eligible for COVID-19 vaccination. Unequal vaccination rates across racial/ethnic groups may compound existing disparities in cases, hospitalizations, and deaths among Black, Indigenous, and Hispanic communities. Methods From state websites, we extracted shares of people receiving ≥1 vaccine dose, stratified by age and separately by race/ethnicity, through March 31, 2021. Combining these data with demographic data from the American Community Survey, we estimated relative uptake rates by race/ethnicity within each state as the observed share of vaccinations for a racial/ethnic group, divided by the expected share if uptake across racial/ethnic groups within each age group were proportional to population size, an approach that allowed us to control for historical age-based eligibility. We modeled vaccination scale-up within each census tract in a state under three scenarios: 1) a scenario in which unequal uptake rates persist, 2) a scenario in which uptake rates are equalized across race/ethnicity groups over six weeks, and 3) a scenario in which uptake is equalized and states employ place-based allocation strategies that prioritizes disadvantaged census tracts. Results White adults received a disproportionate share of vaccinations compared to Black and Hispanic adults through March 31, 2021. Across states, relative uptake rates, adjusted for eligible population size, were a median 1.3 (IQR, 1.2-1.4) times higher for White compared to Black adults, and a median 1.4 (IQR, 1.2-1.8) times higher for White compared to Hispanic adults. Projecting vaccination coverage under persistence of current disparities in uptake, we found that Black and Hispanic populations would reach 75% coverage among adults almost one month later than White populations. In alternative scenarios, we found that interventions to equalize uptake rates across racial/ethnic groups could narrow but not erase these gaps, and that geographic targeting of vaccine doses to disadvantaged communities may be needed to produce a more equitable convergence of coverage by July. Discussion Interventions are urgently needed to eliminate disparities in COVID-19 vaccination rates. Eliminating access barriers and increasing vaccine confidence among marginalized populations can narrow gaps in coverage. Combining these interventions with place-based allocation strategies can accelerate vaccination in disadvantaged communities, who have borne a disproportionate burden from COVID-19.

As the global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic expands, genomic epidemiology and whole genome sequencing are being constantly used to investigate its transmissions and evolution. In the backdrop of the global emergence of variants of concern (VOCs) during December 2020 and an upsurge in a state in the western part of India since January 2021, whole genome sequencing and analysis of spike protein mutations using sequence and structural approaches was undertaken to identify possible new variants and gauge the fitness of current circulating strains. Phylogenetic analysis revealed that the predominant clade in circulation was a distinct newly identified lineage B.1.617 possessing common signature mutations D111D, G142D, L452R, E484Q, D614G and P681R, in the spike protein including within the receptor binding domain (RBD). Of these, the mutations at residue positions 452, 484 and 681 have been reported in other globally circulating lineages. The structural analysis of RBD mutations L452R and E484Q along with P681R in the furin cleavage site, may possibly result in increased ACE2 binding and rate of S1-S2 cleavage resulting in better transmissibility. The same two RBD mutations indicated decreased binding to selected monoclonal antibodies (mAbs) and may affect their neutralization potential. Experimental validation is warranted for accessing both ACE2 binding and the effectiveness of commonly elicited neutralizing mAbs for the strains of lineage B.1.617. The emergence of such local variants through the accumulation of convergent mutations during the COVID-19 second wave needs to be further investigated for their public health impact in the rest of the country and its possibility of becoming a VOC.

<li><strong>Risk perception and optimism bias during the early stages of the COVID-19 pandemic</strong> -

Slowing the spread of COVID-19 requires people to actively change their lives by following protective practices, such as physical distancing and disinfecting their hands. Perceptions about the personal risk of COVID-19 may affect compliance with these practices. In this study, we assessed risk perception and optimism about COVID-19 in a multinational (UK, USA, Germany), longitudinal design during the early stages of the pandemic (16.03.2020; 01.04.2020; 20.05.2020). Our main findings are that 1) people showed a comparative optimism bias about getting infected and infecting others, but not for getting severe symptoms, 2) this optimism bias did not change over time, 3) optimism bias seemed to relate to perceived level of control over the action, 4) risk perception was linked to publicly available information about the disorder (e.g., older people are at a higher risk of getting severe symptoms), and 5) people reported adhering so closely to protective measures that these measures reached ceiling effects. Thus, there was not enough variance in protective measures to appropriately link risk perception and adherence to protective measures. We also collected additional cross-sectional samples, with which we are currently testing which of the findings reported in this preprint replicate. Our results provide detailed descriptions of risk perceptions and optimistic beliefs during the early stages of the COVID-19 pandemic.

Highlighted manuscript Dapsone has been the treatment and preventive drug for mild cognitive impairment, Alzheimer’s disease, Parkinson’s disease, Seizure, Stroke and Covid-19 ARDS. B.K.’s team at Hunt Regional Hospital reported a study that drastically reduced mortality by administering Dapsone to patients with Covid-19 ARDS in the intensive care unit. If Dapsone were used for early symptoms of cognitive impairment or stroke, the increase in deaths would have been prevented. J.H. also recommends it to the elderly living in this pandemic era. However, we must consult our doctor before taking it.

Objective: The Seraph 100 Microbind Affinity Blood Filter (Seraph 100) is an extracorporeal medical countermeasure that can remove many pathogens from blood, including the SARS-CoV-2 virus. The aim of this study was to evaluate safety and efficacy of Seraph 100 treatment for severe coronavirus 2019 disease (COVID-19). Design: Multicenter retrospective observational cohort study. Setting: Intensive care units across four of thirteen participating sites who have completed data extraction. Patients: Critically ill COVID-19 patients treated with Seraph 100 under an Emergency Use Authorization (n=53) and historical control patients who met criteria for treatment (n=46). Intervention: Extracorporeal treatment with the Seraph 100 filter. Measurements and Main Results: At baseline, the median age was 61 years, 72.7% were male, and 59.6% required mechanical ventilation. The groups were matched in terms of sex, race/ethnicity, body mass index, APACHE II score, need for mechanical ventilation, and other COVID-19 treatments. However, patients in the Seraph 100 group were younger with a median age of 61 years (IQR 42-65) compared to controls who had a median age of 64 (IQR 56-68, p=0.036). The Seraph 100 group also had a lower median Charlson comorbidity index (2, IQR 0-3) compared to control patients (3, IQR 2-4, p=0.006). Mortality was lower in the Seraph 100 treated group compared to the historical controls (37.7% vs 67.4%, respectively, p=0.003). Multivariable logistic regression analysis yielded an odds ratio of 0.27 (95% confidence interval 0.09-0.79, p=0.016). Of the 53 patients treated with Seraph 100, only 1 patient experienced a serious adverse event (transient hypotension at the start of the treatment which required a brief period of vasopressor support). Conclusions: These data suggest that broad spectrum, pathogen agnostic, extracorporeal blood purification technologies can be safely deployed to meet new pathogen threats as an adjunct to standard treatments and can mitigate against poor outcomes while awaiting the development of directed pharmacologic therapies and/or vaccines.
