Background Data on the characteristics of COVID-19 patients disaggregated by race/ethnicity remain limited. We evaluated the sociodemographic and clinical characteristics of patients across racial/ethnic groups and assessed their associations with COVID-19 outcomes. Methods This retrospective cohort study examined 629,953 patients tested for SARS-CoV-2 in a large health system spanning California, Oregon, and Washington between March 1 and December 31, 2020. Sociodemographic and clinical characteristics were obtained from electronic health records. Odds of SARS-CoV-2 infection, COVID-19 hospitalization, and in-hospital death were assessed with multivariate logistic regression. Results 570,298 patients with known race/ethnicity were tested for SARS-CoV-2, of whom 27.8% were non-White minorities. 54,645 individuals tested positive, with minorities representing 50.1%. Hispanics represented 34.3% of infections but only 13.4% of tests. While generally younger than White patients, Hispanics had higher rates of diabetes but fewer other comorbidities. 8,536 patients were hospitalized and 1,246 died, of whom 56.1% and 54.4% were non-White, respectively. Racial/ethnic distributions of outcomes across the health system tracked with state-level statistics. Increased odds of testing positive and hospitalization were associated with all minority races/ethnicities. Hispanic patients also exhibited increased morbidity, and Hispanic race/ethnicity was associated with in-hospital mortality (OR: 1.39 [95% CI: 1.14-1.70]). Conclusion Major healthcare disparities were evident, especially among Hispanics who tested positive at a higher rate, required excess hospitalization and mechanical ventilation, and had higher odds of in-hospital mortality despite younger age. Targeted, culturally-responsive interventions and equitable vaccine development and distribution are needed to address the increased risk of poorer COVID-19 outcomes among minority populations.
Estimating an epidemic9s trajectory is crucial for developing public health responses to infectious diseases, but incidence data used for such estimation are confounded by variable testing practices. We show instead that the population distribution of viral loads observed under random or symptom-based surveillance, in the form of cycle threshold (Ct) values, changes during an epidemic and that Ct values from even limited numbers of random samples can provide improved estimates of an epidemic9s trajectory. Combining multiple such samples and the fraction positive improves the precision and robustness of such estimation. We apply our methods to Ct values from surveillance conducted during the SARS-CoV-2 pandemic in a variety of settings and demonstrate new approaches for real-time estimates of epidemic trajectories for outbreak management and response.
Introduction. The onslaught of the COVID-19 pandemic has placed severe demands on US health systems and the health care workforce. In New York State (NYS) and New York City (NYC), the early American epicenter, hospitals ran the risk of exhausting supplies of ventilators, ICU beds, and personal protective equipment (PPE); the capacity of the healthcare workforce to meet the added demand was equally strained. The COVID-19 Healthcare Personnel Study (CHPS) was designed to assess adverse short and long-term physical and mental health impacts of the COVID-19 pandemic on New York9s physicians, nurse practitioners, and physician assistants. Methods. Population-based online survey of physicians, nurse practitioners and physician assistants registered with the New York State Department of Health. Survey-weighted descriptive results were analyzed using frequencies, proportions, and means, with 95% confidence intervals. Odds ratios were calculated for association using survey-weighted logistic regression. Results. Over half (51.5%; 95% CI 49.1, 54.0) of respondents worked directly with COVID-19 patients. Among those tested, 27.3% (95% CI 22.5, 32.2) were positive. The majority (57.6%; 95% CI 55.2, 60.0) of respondents reported that the COVID-19 pandemic had a negative impact on their mental health. Negative mental health was associated with experiencing symptoms of COVID-19 (OR=1.7, 95% CI 1.3, 2.1) and redeployment to unfamiliar functions. (OR=1.3, 95% CI 1.1, 1.6). Conclusions. A majority of New York healthcare providers were involved in treating COVID-19 patients and reported that the pandemic had a negative impact on their mental health.
We studied the incidence of confirmed COVID-19 cases diagnosed during February 24, 2020 - January 10, 2021 in approximately 300 communities making up Los Angeles County, the largest county by population in the United States. The surge in case incidence observed from October 19 onward, accounting for two-thirds of all confirmed cases, was concentrated in communities with a high prevalence of multi-generational households, as gauged by data from the American Community Survey. This indicator (abbreviated MULTI) was a more important predictor of the surge in incidence than the prevalence of households with low income or with at least one high-risk worker. Serial mapping of the epidemic revealed radial expansion from an initial focus in relatively affluent communities, followed by concentration in high-MULTI communities. This observation was supported by estimates from a spatial adaptation of the SIR model, which yielded a reproductive number of 2.7 for the initial outbreak during February 24 - March 30. With the subsequent flattening of the epidemic curve after the imposition of emergency stay-at-home orders, the global reproductive number fell to 1.0, but with wide local dispersion ranging from 0.6 in low-MULTI communities up to 1.5 in high-MULTI communities. The July 13 state-ordered reversal of the county9s prior decisions to reopen retail stores, indoor dining, hair salons, gyms and bars had a larger negative impact on social mobility in high-MULTI communities, as gauged by data from SafeGraph on smartphone visits to fast-food restaurants. After falling to a low of 0.6, the reproductive number rebounded to 1.4 during the final surge. By the end of the 46-week observation period, the estimated cumulative incidence of COVID-19, adjusted for underascertainment of both asymptomatic and symptomatic cases, ranged from under 10 percent in low-MULTI communities to over 30 percent in high-MULTI communities.
The emergence and spread of SARS-CoV-2 lineage B.1.1.7, first detected in the United Kingdom, has become a national public health concern in the United States because of its increased transmissibility. Over 500 COVID-19 cases associated with this variant have been detected since December 2020, but its local establishment and pathways of spread are relatively unknown. Using travel, genomic, and diagnostic testing data, we highlight the primary ports of entry for B.1.1.7 in the US and locations of possible underreporting of B.1.1.7 cases. New York, which receives the most international travel from the UK, is likely one of the key hubs for introductions and domestic spread. Finally, we provide evidence for increased community transmission in several states. Thus, genomic surveillance for B.1.1.7 and other variants urgently needs to be enhanced to better inform the public health response.
The genomic analysis of the 556 viral sequences from Jordan uncovered three dominant genetic SARS-CoV-2 lineages that are currently circulating in Jordan: B.1.1.312 (76%), B.1.36.10 (11%), and B.1.1.7 (6%), replacing the genetic strains that were dominant before sustained community transmission in Jordan. This raises speculations about these new genetic lineages and their relationship to the severity of observed disease symptoms in Jordan.
Introduction: Statins may reduce a cytokine storm, which has been hypothesized as a possible mechanism of severe COVID-19 pneumonia. The aim of this study was to conduct a systematic review and meta-analysis to report on adverse outcomes among COVID-19 patients by statin usage. Methods: Literatures were searched from January 2019 to December 2020 to identify studies that reported the association between statin usage and adverse outcomes, including mortality, ICU admissions, and mechanical ventilation. Studies were meta-analyzed for mortality by the subgroups of ICU status and statin usage before and after COVID-19 hospitalization. Studies reporting an odds ratio (OR) and hazard ratio (HR) were analyzed separately. Results: Thirteen cohorts, reporting on 110,078 patients, were included in this meta-analysis. Individuals who used statins before their COVID-19 hospitalization showed a similar risk of mortality, compared to those who did not use statins (HR 0.80, 95% CI: 0.50, 1.28; OR 0.62, 95% CI: 0.38, 1.03). Patients who were administered statins after their COVID-19 diagnosis were at a lower risk of mortality (HR 0.53, 95% CI: 0.46, 0.61; OR 0.57, 95% CI: 0.43, 0.75). The use of statins did not reduce the mortality of COVID-19 patients admitted to the ICU (OR 0.65; 95% CI: 0.26, 1.64). Among non-ICU patients, statin users were at a lower risk of mortality relative to non-statin users (HR 0.53, 95% CI: 0.46, 0.62; OR 0.64, 95% CI: 0.46, 0.88). Conclusion: Patients administered statins after COVID-19 diagnosis or non-ICU admitted patients were at lower risk of mortality relative to non-statin users.
New York City (NYC) emerged as a coronavirus disease 2019 (COVID-19) epicenter in March 2020, but there is limited information regarding potentially unrecognized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections before the first reported case. We utilized a sample pooling strategy to screen for SARS-CoV-2 RNA in de-identified, respiratory pathogen-negative nasopharyngeal specimens from 3,040 patients across our NYC health system who were evaluated for respiratory symptoms or influenza-like illness during the first 10 weeks of 2020. We obtained complete SARS-CoV-2 genome sequences from samples collected between late February and early March. Additionally, we detected SARS-CoV-2 RNA in pooled specimens collected in the week ending 25 January 2020, indicating that SARS-CoV-2 caused sporadic infections in NYC a full month before the first officially documented case.

Early detection of neutralizing antibodies against SARS-CoV-2 in COVID-19 patients in Thailand - CONCLUSION: The sVNT is a practical and robust serological test for SARS-CoV-2 infection and does not require specialized biosafety containment. It can be used clinically to aid diagnosis in both early and late infection especially in cases when the real-time RT-PCR results in weakly negative or weakly positive, and to determine the protective immune response from SARS-CoV-2 infection in patients.
Kobophenol A Inhibits Binding of Host ACE2 Receptor with Spike RBD Domain of SARS-CoV-2, a Lead Compound for Blocking COVID-19 - In the search for inhibitors of COVID-19, we have targeted the interaction between the human angiotensin-converting enzyme 2 (ACE2) receptor and the spike receptor binding domain (S1-RBD) of SARS-CoV-2. Virtual screening of a library of natural compounds identified Kobophenol A as a potential inhibitor. Kobophenol A was then found to block the interaction between the ACE2 receptor and S1-RBD in vitro with an IC(50) of 1.81 ± 0.04 μM and inhibit SARS-CoV-2 viral infection in cells with an EC(50)…
High neutralizing potency of swine glyco-humanized polyclonal antibodies against SARS-CoV-2 - Heterologous polyclonal antibodies might represent an alternative to the use of convalescent plasma (CP) or monoclonal antibodies (mAbs) in COVID-19 by targeting multiple antigen epitopes. However, heterologous antibodies trigger human natural xenogeneic antibody responses particularly directed against animal-type carbohydrates, mainly the N-glycolyl form of the neuraminic acid (Neu5Gc) and the Gal α1,3-galactose (αGal), potentially leading to serum sickness or allergy. Here, we immunized…
