Vaccination has been used for the prevention and eradication of communicable diseases such as smallpox, polio, and measles. Herd immunity and immunity threshold have already been conceptualized for the prevention of outbreaks and pandemicity of these diseases. Coronavirus infectious disease-19 (COVID-19) is the second pandemic coronavirus disease of the 21st century. Vaccination has been conducted since December 2020 in an attempt to control the pandemic. The morbidity and incidence of COVID-19 has decreased since the initiation of the vaccination program within Israel, the United Kingdom, and the United States. However, irregular vaccine rollout and uneven distribution of vaccine is a major barrier to vaccine access. Moreover, genetic variants of the severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) could be a barrier to immunity.

Questions of migration and citizenship are at the heart of global political debate with Brexit and the election of Donald Trump having ripple effects around the world. Providing new insights into the politics of migration and citizenship in the United Kingdom and the United States, this book challenges the increasingly prevalent view of migration and migrants as threats and of formal citizenship as a necessary marker of belonging. Instead the book offers an analysis of migration and citizenship in practice, as a counterpoint to simplistic discourses. It uses cutting-edge academic work on migration and citizenship to address three themes central to current debates: borders and walls, mobility and travel, and belonging. Through this analysis, a clearer picture of the roots of these politics emerges as well as of the consequences for mobility, political participation and belonging in the 21st century.

Modern Sense

Commercialization of journalism is not a new concern. Indeed, journalism has always been bought and sold in the market, and commercialization has thus always been a central part of the production of journalism. In a modern sense, however, commercialization became an issue with the emergence of the penny press in the United States and the abolishment of the “taxes on knowledge” in the United Kingdom. These developments altered the content of newspapers and brought along discussions concerning the effects of commercialization. In the late 20th and early 21st century, commercialization of journalism again took a new turn. Developments such as digitalization and the emergence and communization of the internet, has led to an increased attention to market logics. This, in turn, makes studies of the commercialization of journalism increasingly more important.

BACKGROUND Given the extensive time needed to conduct a nationally representative household survey and the commonly low response rate of phone surveys, rapid online surveys may be a promising method to assess and track knowledge and perceptions among the general public during fast-moving infectious disease outbreaks. OBJECTIVE This study aimed to apply rapid online surveying to determine knowledge and perceptions of coronavirus disease 2019 (COVID-19) among the general public in the United States and the United Kingdom. METHODS An online questionnaire was administered to 3000 adults residing in the United States and 3000 adults residing in the United Kingdom who had registered with Prolific Academic to participate in online research. Prolific Academic established strata by age (18-27, 28-37, 38-47, 48-57, or ≥58 years), sex (male or female), and ethnicity (white, black or African American, Asian or Asian Indian, mixed, or “other”), as well as all permutations of these strata. The number of participants who could enroll in each of these strata was calculated to reflect the distribution in the US and UK general population. Enrollment into the survey within each stratum was on a first-come, first-served basis. Participants completed the questionnaire between February 23 and March 2, 2020. RESULTS A total of 2986 and 2988 adults residing in the United States and the United Kingdom, respectively, completed the questionnaire. Of those, 64.4% (1924/2986) of US participants and 51.5% (1540/2988) of UK participants had a tertiary education degree, 67.5% (2015/2986) of US participants had a total household income between US $20,000 and US $99,999, and 74.4% (2223/2988) of UK participants had a total household income between £15,000 and £74,999. US and UK participants’ median estimate for the probability of a fatal disease course among those infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was 5.0% (IQR 2.0%-15.0%) and 3.0% (IQR 2.0%-10.0%), respectively. Participants generally had good knowledge of the main mode of disease transmission and common symptoms of COVID-19. However, a substantial proportion of participants had misconceptions about how to prevent an infection and the recommended care-seeking behavior. For instance, 37.8% (95% CI 36.1%-39.6%) of US participants and 29.7% (95% CI 28.1%-31.4%) of UK participants thought that wearing a common surgical mask was “highly effective” in protecting them from acquiring COVID-19, and 25.6% (95% CI 24.1%-27.2%) of US participants and 29.6% (95% CI 28.0%-31.3%) of UK participants thought it was prudent to refrain from eating at Chinese restaurants. Around half (53.8%, 95% CI 52.1%-55.6%) of US participants and 39.1% (95% CI 37.4%-40.9%) of UK participants thought that children were at an especially high risk of death when infected with SARS-CoV-2. CONCLUSIONS The distribution of participants by total household income and education followed approximately that of the US and UK general population. The findings from this online survey could guide information campaigns by public health authorities, clinicians, and the media. More broadly, rapid online surveys could be an important tool in tracking the public’s knowledge and misperceptions during rapidly moving infectious disease outbreaks.
