RESUMO

In recent decades, a culture of hopelessness has emerged among rural Americans, visible in epidemic levels of suicide, overdose, and other addiction-related illnesses. While the arrival of a novel coronavirus aggravated existing strains in rural economies, it also enabled positive transformations in some rural cities and towns. This research explores how businesses in rural America experienced and adapted to economic shocks caused by the Covid-19 pandemic and, in the process, changed the economic and social landscape. Applying a qualitative research methodology, the present research offers Pennsylvania's Central Susquehanna Valley as a case study, using data from 60 semi-structured interviews. The analyses demonstrate rural businesses' resiliency and adaptive responses, bolstered by embedded rural capitals and the unique characteristics of rural businesses themselves. Furthermore, the pandemic forced drastic changes for businesses in the rural landscape. On the one hand, Covid-19's losses and miseries take much material, human, and social resources from the rural community. On the other hand, changing relationships between businessowners and workers, and among partners in the supply chain could be long-lasting, creating extra rural capitals and better working relationships at the factory and beyond. Finally, adoption of new technologies and automation; new business directions, such as e-commerce and higher value-added production; and increases in mergers and acquisitions across industries were prevalent during 2020-2021. In many ways, the Covid-19 impacts could make rural America more dynamic and competitive. This research offers conceptual and empirical pathways to supporting economic and social development in rural America.

RESUMO

This research asks: To what extent has America's reliance on the global supply network aggravated the country's public health and economic crisis; and how did the American government respond to supply chain weaknesses during the early years of the Covid-19 pandemic? This study first assesses important conceptual considerations that explain the expansion of global value chains and the growth of trade interdependencies among nations. Next, an analytical case study observes (1) America's supply chain vulnerability through three major waves of infection, (2) the difficulty to mend weaknesses in the supply linkages once the novel coronavirus spread globally and (3) American government's failures to both anticipate and respond to supply shortages, especially in the health sector. Trump administration's policies failed to ensure a reliable supply of simple personal protective equipment (PPE) for healthcare professionals and hospitals throughout the first three waves of infection. Moreover, state and federal governments' substantial reliance on large manufacturers who have established procurement relationship with government led to continuous nationwide supply shortages throughout 2020. The federal government's inability to engage small and medium manufacturers in the production of critical supplies of PPE and diagnostic tests deepened and prolonged the devastating impacts of the pandemic. Our case study demonstrates that the American government needs to rethink the country's substantial reliance on the global supply chain, and the specific requirements to boost domestic manufacturing capacity. The revitalisation of America's manufacturing ability and the local supply networks will boost the productive power of the nation, strengthen resiliency, reduce vulnerability in disruptive times and prepare the nation for future crises.

RESUMO

Co-infections with different variants of SARS-CoV-2 are a key precursor to recombination events that are likely to drive SARS-CoV-2 evolution. Rapid identification of such co-infections is required to determine their frequency in the community, particularly in populations at-risk of severe COVID-19, which have already been identified as incubators for punctuated evolutionary events. However, limited data and tools are currently available to detect and characterise the SARS-CoV-2 co-infections associated with recognised variants of concern. Here we describe co-infection with the SARS-CoV-2 variants of concern Omicron and Delta in two epidemiologically unrelated adult patients with chronic kidney disease requiring maintenance haemodialysis. Both variants were co-circulating in the community at the time of detection. Genomic surveillance based on amplicon- and probe-based sequencing using short- and long-read technologies identified and quantified subpopulations of Delta and Omicron viruses in respiratory samples. These findings highlight the importance of integrated genomic surveillance in vulnerable populations and provide diagnostic pathways to recognise SARS-CoV-2 co-infection using genomic data.

RESUMO

BACKGROUND: The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA by reverse-transcription polymerase chain reaction (PCR) does not necessarily indicate shedding of infective virions. There are limited data on the correlation between the isolation of SARS-CoV-2, which likely indicates infectivity, and PCR. METHODS: A total of 195 patients with Coronavirus disease 2019 were tested (outpatients, n = 178; inpatients, n = 12; and critically unwell patients admitted to the intensive care unit [ICU] patients, n = 5). SARS-CoV-2 PCR-positive samples were cultured in Vero C1008 cells and inspected daily for cytopathic effect (CPE). SARS-CoV-2-induced CPE was confirmed by PCR of culture supernatant. Where no CPE was observed, PCR was performed on day 4 to confirm absence of virus replication. The cycle thresholds (Cts) of the day 4 PCR (Ctculture) and the PCR of the original clinical sample (Ctsample) were compared, and positive cultures were defined where Ctsample - Ctculture was ≥3. RESULTS: Of 234 samples collected, 228 (97%) were from the upper respiratory tract. SARS-CoV-2 was isolated from 56 (24%), including in 28 of 181 (15%), 19 of 42 (45%), and 9 of 11 samples (82%) collected from outpatients, inpatients, and ICU patients, respectively. All 56 samples had Ctsample ≤32; CPE was observed in 46 (20%). The mean duration from symptom onset to culture positivity was 4.5 days (range, 0-18). SARS-CoV-2 was significantly more likely to be isolated from samples collected from inpatients (P < .001) and ICU patients (P < .0001) compared with outpatients, and in samples with lower Ctsample. CONCLUSIONS: SARS-CoV-2 culture may be used as a surrogate marker for infectivity and inform de-isolation protocols.
