Letter textThe prevalence of asymptomatic COVID-19 infections is largely unknown and may determine the course of future pandemic waves and the effectiveness of interventions. Using an epidemiological model fit to COVID-19 hospitalization counts from New York City, New York and Austin, Texas, we found that the undocumented attack rate in the first pandemic wave depends on the proportion of asymptomatic infections but not on the infectiousness of such individuals. Based on a recent report that 22.7% of New Yorkers are seropositive for SARS-CoV-2, we estimate that 56% (95% CI: 53-59%) of COVID-19 infections are asymptomatic. Given uncertainty in the case hospitalization rate, however, the asymptomatic proportion could be as low as 20% or as high as 80%. We find that at most 1.26% of the Austin population was infected by April 27, 2020 and conclude that immunity from undetected infections is unlikely to slow future pandemic spread in most US cities in the summer of 2020.

On Staten Island in the spring of 1945, a small group of white politicians, business owners, and residents began complaining about a “crime wave” that they attributed to black soldiers stationed at the Fox Hills Army facility. Most of these complaints stemmed from vague references to rumors of crimes rather than actual incidents. Black journalists and members of the NAACP refuted these accusations and argued that the real issue was discrimination against the soldiers and racism on the part of white Staten Islanders. These accusations launched a months-long debate about racism, crime, and policing on Staten Island during the war. Ultimately, the mayor and military authorities responded by intensifying policing and surveillance of the soldiers. This article uses the conflicts around policing in wartime Staten Island as a lens to consider the impact of the war on black New Yorkers and black soldiers stationed in New York City.

Historians have conducted important research on the rise of law-and-order politics in New York City, where anxieties over women’s freedoms, political battles over police oversight, and crime impacts in poor communities contributed to its rise. The numerous walkouts, negotiations, and worker-management conflicts around high-crime areas in New York City suggest that the question of law and order was a salient workplace issue as well for the members of Communication Workers of America Local 1101. In their case, such concerns predate the rhetorical rise of law and order and help us better understand why such politics found fertile ground among working-class New Yorkers, white and black. Repeated incidences, largely in the city’s black ghettoes, prompted workers with a strong class consciousness and commitment to solidarity to transform the problems and experiences of individual workers into a shared question to be addressed via collective action.

New York City launched a restaurant sanitation letter grade system in 2010. We evaluate the impact of customer loyalty on restaurant revisit intentions after exposure to a sanitation grade alone, and after exposure to a sanitation grade plus narrative information about sanitation violations (e.g., presence of rats). We use a 2 (loyalty: high or low) × 4 (sanitation grade: A, B, C, or pending) between-subjects full factorial design to test the hypotheses using data from 547 participants recruited from Amazon MTurk who reside in the New York City area. Our study yields three findings. First, loyal customers exhibit higher intentions to revisit restaurants than non-loyal customers, regardless of sanitation letter grades. Second, the difference in revisit intentions between loyal and non-loyal customers is higher when sanitation grades are poorer. Finally, loyal customers are less sensitive to narrative information about sanitation violations.

10572 Background: Several reports have suggested that cancer patients are at increased risk for contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and suffering worse coronavirus disease 2019 (COVID-19) outcomes. However, little is known about the impact of cancer status on presentation and outcome. Here, we report on the association between cancer status and survival in hospitalized patients who tested positive for SARS-CoV-2 during the height of pandemic in New York City. Methods: Of the 6,724 patients who were hospitalized at NYU Langone Health (3/16/20 - 7/31/20) and tested positive for SARS-CoV-2, 580 had either active cancer (n = 221) or a history of cancer (n = 359). Patients were classified as having active malignancy if they either received treatment within six months of their COVID-19 diagnosis or they had measurable disease documented at the time of their hospitalization. Patients were categorized as having a history of cancer if there was no evidence of measurable disease or there were no treatments administered within six months of their COVID-19 diagnosis. We compared the baseline clinicodemographic characteristics and hospital courses of the two groups, and the relationship between cancer status and the rate of admission to the intensive care unit (ICU), use of invasive mechanical ventilation (IMV), and all-cause mortality. Results: There was no differences between the two groups in their baseline laboratory results associated with COVID-19 infection, incidence of venous thromboembolism, or incidence of severe COVID-19. Active cancer status was not associated with the rate of ICU admission ( P = 0.307) or use of IMV ( P = 0.236), but was significantly associated with worse all-cause mortality in both univariate and multivariate analysis with ORs of 1.48 (95% CI: 1.04-2.09; P = 0.028) and 1.71 (95% CI: 1.12-2.63; P = 0.014), respectively. Conclusions: Active cancer patients had worse survival outcomes compared to patients with a history of cancer despite similar COVID-19 disease characteristics in the two groups. Our data suggest that cancer care should continue with minimal interruptions during the pandemic to bring about response and remission as soon as possible. Additionally, these findings support the growing body of evidence that malignancy portends worse COVID-19 prognosis, and demonstrate that the risk may even apply to those without active disease.
