ABSTRACT In December of 2019, a novel coronavirus, SARS-CoV-2, emerged in the city of Wuhan, China, causing severe morbidity and mortality. Since then, the virus has swept across the globe, causing millions of confirmed infections and hundreds of thousands of deaths. To better understand the nature of the pandemic and the introduction and spread of the virus in Arizona, we sequenced viral genomes from clinical samples tested at the TGen North Clinical Laboratory, the Arizona Department of Health Services, and those collected as part of community surveillance projects at Arizona State University and the University of Arizona. Phylogenetic analysis of 84 genomes from across Arizona revealed a minimum of 11 distinct introductions inferred to have occurred during February and March. We show that >80% of our sequences descend from strains that were initially circulating widely in Europe but have since dominated the outbreak in the United States. In addition, we show that the first reported case of community transmission in Arizona descended from the Washington state outbreak that was discovered in late February. Notably, none of the observed transmission clusters are epidemiologically linked to the original travel-related case in the state, suggesting successful early isolation and quarantine. Finally, we use molecular clock analyses to demonstrate a lack of identifiable, widespread cryptic transmission in Arizona prior to the middle of February 2020. IMPORTANCE As the COVID-19 pandemic swept across the United States, there was great differential impact on local and regional communities. One of the earliest and hardest hit regions was in New York, while at the same time Arizona (for example) had low incidence. That situation has changed dramatically, with Arizona now having the highest rate of disease increase in the country. Understanding the roots of the pandemic during the initial months is essential as the pandemic continues and reaches new heights. Genomic analysis and phylogenetic modeling of SARS-COV-2 in Arizona can help to reconstruct population composition and predict the earliest undetected introductions. This foundational work represents the basis for future analysis and understanding as the pandemic continues.

Among The Many Significant Contributions of Raúl Coronado's A World Not to Come: A History Of Latino Writing and Print Culture is its vivid account of a lost Latino public sphere, a little-known milieu of hispanophone intellectual culture dating back to the early nineteenth century and formed in the historical interstices of Spanish American colonies, emergent Latin American nations, and the early imperial interests of the United States. In this respect, the book builds on the foundational work of Kirsten Silva Gruesz's Ambassadors of Culture: The Transamerican Origins of Latino Writing, which gave definitive shape to the field of early Latino studies by addressing what were then (and in some ways still are) the “methodological problems of proposing to locate the ‘origins’ of Latino writing in the nineteenth century.” Gruesz unfolded a vast panorama of forgotten Spanish-language print culture throughout the United States, from Philadelphia and New York to New Orleans and California, in which letters, stories, essays, and above all poetry bequeathed what she showed convincingly were “important, even crucial, ways of understanding the world” that had been largely lost to history (x). Coronado's book carries forward this project of recovery, exploring a particular scene of early Latino writing centered in Texas during its last revolutionary decades as one of the Interior Provinces of New Spain, its abrupt transition to an independent republic, and its eventual annexation by the United States. As a “history of textuality” rather than a study of literary culture per se (28), the book tells the story of the first printing presses in Texas but also evinces the importance of manuscript circulation as well as private and sometimes unfinished texts. A World Not to Come concerns both print culture and origins but refuses to fetishize either, attending to the past not to “the degree that it is a measure of the future,” as Rosaura Sánchez once put it, but for the very opposite reason: because it portended a future that was never realized (qtd. in Gruesz, Ambassadors xi).

The novel coronavirus (COVID-19) pandemic presents a severe threat to human health worldwide. The United States (US) has the highest number of reported COVID-19 cases, and over 16 million people were infected up to the 12 December 2020. To better understand and mitigate the spread of the disease, it is necessary to recognize the pattern of the outbreak. In this study, we explored the patterns of COVID-19 cases in the US from 1 March to 12 December 2020. The county-level cases and rates of the disease were mapped using a geographic information system (GIS). The overall trend of the disease in the US, as well as in each of its 50 individual states, were analyzed by the seasonal-trend decomposition. The disease curve in each state was further examined using K-means clustering and principal component analysis (PCA). The results showed that three clusters were observed in the early phase (1 March–31 May). New York has a unique pattern of the disease curve and was assigned one cluster alone. Two clusters were observed in the middle phase (1 June–30 September). California, Texas and Florida were assigned in the same cluster, which has the pattern different from the remaining states. In the late phase (1 October–12 December), California has a unique pattern of the disease curve and was assigned a cluster alone. In the whole period, three clusters were observed. California, Texas and Florida still have similar patterns and were assigned in the same cluster. The trend analysis consolidated the patterns identified from the cluster analysis. The results from this study provide insight in making disease control and mitigation strategies.

AbstractWith new cases of Covid-19 surging in the United States, we need to better understand how the spread of novel coronavirus varies across all segments of the population. We use hierarchical exponential growth curve modeling techniques to examine whether community social and economic characteristics uniquely influence the incidence of Covid-19 cases in the urban built environment. We show that, as of May 3, 2020, confirmed coronavirus infections are concentrated along demographic and socioeconomic lines in New York City and surrounding areas, the epicenter of the Covid-19 pandemic in the United States. Furthermore, we see evidence that, after the onset of the pandemic, timely enactment of physical distancing measures such as school closures is imperative in order to limit the extent of the coronavirus spread in the population. Public health authorities must impose nonpharmaceutical measures early on in the pandemic and consider community-level factors that associate with a greater risk of viral transmission.

AbstractApproximately, 1.7 million individuals in the United States have been infected with SARS-CoV-2, the virus responsible for the novel coronavirus disease-2019 (COVID-19). This has disproportionately impacted adults, but many children have been infected and hospitalised as well. To date, there is not much information published addressing the cardiac workup and monitoring of children with COVID-19. Here, we share the approach to the cardiac workup and monitoring utilised at a large congenital heart centre in New York City, the epicentre of the COVID-19 pandemic in the United States.

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.

Forty-eight hours after they landed in New York City in 1880, a small contingent of the Salvation Army held their first public meeting at the infamous Harry Hill's Variety Theater. The enterprising Hill, alerted to the group's arrival from Britain by newspaper reports, contacted their leader, Commissioner George Scott Railton, and offered to pay the group to “do a turn” for “an hour or two on … Sunday evening.” In nineteenth-century New York City, Harry Hill's was one of the best known concert saloons, and reformers considered him “among the disreputable classes” of that city. His saloon, they said, was “nothing more than one of the many gates to hell.”
