Airborne Transmission

A quantitative analysis of the viral transmission risk in public spaces al- lows us to identify the dominant mechanisms that a proactive public health policy can act upon to reduce risk, and to evaluate the reduction of risk that can be obtained. The contribution of public spaces to the propa- gation of SARS-CoV-2 can be reduced to a level necessary for a declining epidemic, i.e. an overall reproduction rate below one. Here, we revisit the quantitative assessment of indoor and outdoor transmission risk. We show that the long-range aerosol transmission is controlled by the flow rate of fresh air and by the mask filtering quality, and is quantitatively re- lated to the CO2 concentration, regardless the room volume and the num- ber of people. The short-range airborne transmission is investigated ex- perimentally using dedicated dispersion experiments performed in two shopping malls. Exhaled aerosols are dispersed by turbulent draughts in a cone, leading to a concentration inversely proportional to the squared dis- tance and to the flow velocity. We show that the average infection dose, called the viral quantum, can be determined from epidemiological data in a manner consistent with biological experimental data. Practical implications. The results provide quantitative guidance useful for making rational public health policy decisions to prevent the dominant routes of viral transmission through reinforced ventilation, air purification, mechanical dispersion using fans, and incentivizing the wear- ing of correctly fitted, quality facial masks (surgical masks, possibly cov- ered by another fabric mask, or non-medical FFP2 masks). Taken to- gether, such measures significantly reduce the airborne transmission risk of SARS-CoV-2.

This chapter explores the powers of Congress to pass federal public health laws and to delegate authority to federal agencies. The chapter starts with an explanation of Congress’s limited, enumerated powers and how this limits Congress to certain arenas of authority. It next explores the evolution Congress’s use of the Commerce Clause to pass public health laws, before exploring Congress’s use of the Taxing and Spending Clause. The chapter provides examples of how Congress has used both the Commerce Clause and its taxing and spending power to effectuate public health policy. Next, the chapter explains the National Federation of Independent Businesses v. Sebelius case; it details challenges to the Affordable Care Act’s individual mandate and Medicaid and explains the implications of the Supreme Court’s holdings. Lastly, the chapter explains Congress’s authority to delegate authority to federal administrative agencies to issue and enforce public health regulations.

This chapter draws on medical, social, and legal perspectives to identify and highlight ethical issues pertaining to the treatment, representation, and inclusion of persons with disabilities in public health policy and practice. A brief history of disability in the United States is provided as a context for examining the key ethical issues related to public health policy and practice. Conceptual frameworks and approaches to disability are then described and applied. The chapter then discusses the imperativeness of expanding access to public health programs by persons with disabilities, the need to address implicit and structural biases, and the importance of including persons with disabilities in public health decision-making.

Health Policy And Practice

Television (TV) news, and especially local TV news, remains an important vehicle through which Americans obtain information about health-related topics. In this review, we synthesize theory and evidence on four main functions of TV news in shaping public health policy and practice: reporting events and information to the public (surveillance); providing the context for and meaning surrounding health issues (interpretation); cultivating community values, beliefs, and norms (socialization); and attracting and maintaining public attention for advertisers (attention merchant). We also identify challenges for TV news as a vehicle for improving public health, including declining audiences, industry changes such as station consolidation, increasingly politicized content, potential spread of misinformation, and lack of attention to inequity. We offer recommendations for public health practitioners and researchers to leverage TV news to improve public health and advance health equity.

Good Decision

Although empirical evidence may provide a much desired sense of certainty amidst a pandemic characterised by uncertainty, the vast gamut of available COVID-19 data, including misinformation, has instead increased confusion and distrust in authorities’ decisions. One key lesson we have been gradually learning from the COVID-19 pandemic is that the availability of empirical data and scientific evidence alone do not automatically lead to good decisions. Good decision-making in public health policy, this paper argues, does depend on the availability of reliable data and rigorous analyses, but depends above all on sound ethical reasoning that ascribes value and normative judgement to empirical facts.
