Abstract This paper investigates the mortality statistics of the COVID-19 pandemic from the United States perspective. Using empirical data analysis and statistical inference tools, we bring out several exciting and important aspects of the pandemic, otherwise hidden. Specific patterns seen in demo- graphics such as race/ethnicity and age are discussed both qualitatively and quantitatively. We also study the role played by factors such as population density. Connections between COVID-19 and other respiratory diseases are also covered in detail. The temporal dynamics of the COVID-19 outbreak and the impact of vaccines in controlling the pandemic are also looked at with suf- ficient rigor. It is hoped that statistical inference such as the ones gathered in this paper would be helpful for better scientific understanding, policy prepa- ration and thus adequately preparing, should a similar situation arise in the future.

The Impact

Background: The first shelter-in-place (SIP) order in the United States was issued across six counties in the San Francisco Bay Area to reduce the impact of COVID-19 on critical care resources. We sought to assess the impact of this large-scale intervention on emergency departments (ED) in Marin County, California. Methods: We conducted a retrospective descriptive and trend analysis of all ED visits in Marin County, California from January 1, 2018 to May 4, 2020 to quantify the temporal dynamics of ED utilization before and after the March 17, 2020 SIP order. Results: The average number of ED visits per day decreased by 52.3% following the SIP order compared to corresponding time periods in 2018 and 2019. Both respiratory and non-respiratory visits declined, but this negative trend was most pronounced for non-respiratory admissions. Conclusions: The first SIP order to be issued in the United States in response to COVID-19 was associated with a significant reduction in ED utilization in Marin County.

The recent settlement of immigrant populations into a wider range of geographies and communities across the United States raises new questions about the dynamics of residential segregation and complicates assumptions about how neighborhoods change—or don't—and why. While multiple theories attempt to explain the relationship between race/ethnicity, immigration, and neighborhood change, sociological examinations have been limited by the lack of systematic and frequently collected data. That is, the residential churn of neighborhoods, particularly in the market for rental housing where racial/ethnic minorities and immigrants predominate, often outpaces analysts’ ability to gather cross–neighborhood and cross–city data. In this essay we describe how online sources can help answer questions about race/ethnicity, immigration, and neighborhoods by providing large amounts of readily updatable data. An array of platforms designed to provide homeseekers with information about their housing options can also be used by sociologists for making claims about neighborhood change across multiple geographies. We review recent research that uses online data and describe an ongoing study by the authors that examines trends in the settlement patterns of immigrants and the rental housing market across the 50 largest MSAs in the United States. Online data sources can more accurately capture immigration and neighborhood processes, yielding better theories about the impact of immigration on neighborhood change.

The Impact

North Korea has repeatedly defied the international community with regards to its nuclear weapons programme. Many look to China for leverage to change North Korea’s behaviour. This study reviews the development of the China–North Korean relationship and conducts a statistical analysis on the impact of China’s influence on North Korea. Our analysis finds China’s leverage on North Korea to be nuanced. We maintain that North Korea has been wary of China’s influence. Complete isolation or pressure from China under certain conditions will render North Korea more resistant to China’s influence. We also suggest that the key to the North Korean issue is still in the hands of the United States and the entire international community through the use of an engagement strategy.

Race, ethnicity, and gender issues have always been important matters in American politics. However, during the past two presidential elections these issues were the vanguard topics displayed on centerstage. The United Sates has a tainted history with respects to certain populations which it has discriminated against and marginalized throughout the country's history, and the tensions surrounding these issues erupted like a volcano. The United States became polarized as people began to align with different political and social ideologies depicting how those who are regarded as being different, “others”, should be treated. This chapter provides a brief history of marginalized populations in the United States and uses Critical Race Theory and self-awareness as means to help the reader understand the impact on society when racism and inequality are woven into the fabric of the country.

The Impact

Respiratory diseases affect millions of people across the United States annually. Two of the most common respiratory diseases are chronic obstructive pulmonary disease (COPD) and asthma. Mortality rates due to COPD have increased by an estimated 30% between 1980 and 2014, with significant variances among geographic regions. Both acute and chronic ambient exposures to fine particulate matter (PM2.5) and ozone have been associated with exacerbations of respiratory diseases in numerous studies, and exposure to air pollutants are considered as the largest health risk factor globally. This study adds to the current literature by reporting the results of a time series analysis of the impact of PM2.5 and ozone on prevalence rates of asthma and mortality rates for COPD at regional and county levels across the southeastern United States for the years 2005–2014. While general reductions in levels of PM2.5 and ozone were demonstrated across all years, a distributed lag model showed continued strong associations between PM2.5 and prevalence of asthma and mortality due to COPD, even at relatively small increases in ambient exposure (<1 μg/m3) across the southeastern United States. The results of the study support the need for additional research that considers factors such as patient demographics, medical histories, and health disparities in combination with ambient exposures to known pollutants.

The Impact

The impact of COVID-19 public health interventions on pediatric illnesses nationwide is unknown. We performed a multicenter, cross-sectional study of encounters at 44 children’s hospitals in the United States to assess changes in healthcare utilization during the pandemic. The COVID-19 pandemic was associated with substantial reductions in encounters for respiratory diseases; these large reductions were consistent across illness subgroups. Although encounters for nonrespiratory diseases decreased as well, reductions were more modest and varied by age. Encounters for respiratory diseases among adolescents declined to a lesser degree and returned to previous levels faster compared with those of younger children. Further study is needed to determine the contributions of decreased illness and changes in care-seeking behavior to this observed reduction.

The Impact

SUMMARYThe United States national mortality statistics and HIV/AIDS surveillance data were analysed to determine trends in encephalitis-associated deaths and to assess the impact of HIV infection on those deaths during 1979–1998, a period when ICD-9 codes were used for coding deaths in the United States. A total of 25 125 encephalitis deaths were reported; 4779 of them (19%) had concurrent HIV infection. Overall encephalitis death rates remained stable, but they increased for groups where HIV infection was common and declined or remained unchanged for others. For persons without HIV infection, the rates declined in all demographic groups. Encephalitis deaths in HIV-infected persons followed general trends for HIV deaths in the United States. The rates in the HIV-infected population were several hundred- to thousand-fold higher than in the HIV-uninfected population. HIV infection was largely responsible for the lack of overall decline in the considerable mortality associated with encephalitis in the United States during 1979–1998.
