Estimating the Effectiveness of Non-Pharmaceutical Interventions on COVID-19 Control in Korea.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has posed significant global public health challenges and created a substantial economic burden. Korea has experienced an extensive outbreak, which was linked to a religion-related super-spreading event. However, the implementation of various non-pharmaceutical interventions (NPIs), including social distancing, spring semester postponing, and extensive testing and contact tracing controlled the epidemic. Herein, we estimated the effectiveness of each NPI using a simulation model. METHODS: A compartment model with a susceptible-exposed-infectious-quarantined-hospitalized structure was employed. Using the Monte-Carlo-Markov-Chain algorithm with Gibbs' sampling method, we estimated the time-varying effective contact rate to calibrate the model with the reported daily new confirmed cases from February 12th to March 31st (7 weeks). Moreover, we conducted scenario analyses by adjusting the parameters to estimate the effectiveness of NPI. RESULTS: Relaxed social distancing among adults would have increased the number of cases 27.4-fold until the end of March. Spring semester non-postponement would have increased the number of cases 1.7-fold among individuals aged 0-19, while lower quarantine and detection rates would have increased the number of cases 1.4-fold. CONCLUSION: Among the three NPI measures, social distancing in adults showed the highest effectiveness. The substantial effect of social distancing should be considered when preparing for the 2nd wave of COVID-19.

Lessons from the Field: Lessons from Yap - Changing Government and Cultural Practice Through Public Health Policy.

The heavy burden of non-communicable diseases (NCD) in Yap State, Federated States of Micronesia overwhelms the resources of this small population. Traditional cultural practices strongly influence all aspects of life, especially in the remote outer islands. The traditional Chiefs must grant permission to perform any type of health outreach or services for about one-third of the population. One key cultural practice promotes tobacco and alcohol use. The Yap Comprehensive Cancer Control Program, in collaboration with other entities in public health, systematically engaged the traditional Chiefs, resulting in a landmark policy that paved the way for other system and environmental interventions to reduce the risks of developing NCD.

Multilevel governance, public health and the regulation of food: is tobacco control policy a model?

Campaigns against risk factors for non-communicable diseases (NCDs) caused by smoking and obesity have become increasingly common on multiple levels of government, from the local to the international. Non-governmental actors have cooperated with government bodies to make policies. By analysing the policies of the World Trade Organization, the World Health Organization, the European Union, and the United Kingdom and United States governments, we identify how the struggles between public health advocates and commercial interests reached the global level, and how the relatively successful fight to 'denormalize' tobacco consumption has become a model for anti-obesity advocates. It highlights three factors important in policy change: framing the policy problem, the policymaking environment and 'windows of opportunity'-to analyse the struggle between 'harm regulation' and 'neoprohibition' approaches to an international obesity prevention regime.

Major trends in public health law and practice: a network national report.

Since its inception in September 2010, the Network for Public Health Law has responded to hundreds of public health legal technical assistance claims from around the country. Based on a review of these data, a series of major trends in public health practice and the law are analyzed, including issues concerning: the Affordable Care Act, tobacco control, emergency legal preparedness, health information privacy, food policy, vaccination, drug overdose prevention, sports injury law, public health accreditation, and maternal breastfeeding. These and other emerging themes in public health law demonstrate the essential role of law and practice in advancing the public's health.

Mandatory and recommended vaccination in the EU, Iceland and Norway: results of the VENICE 2010 survey on the ways of implementing national vaccination programmes.

This report provides an updated overview of recommended and mandatory vaccinations in the European Union (EU), Iceland and Norway, considering the differences in vaccine programme implementation between countries. In 2010, the Vaccine European New Integrated Collaboration Effort (VENICE) network, conducted a survey among the VENICE project gatekeepers to learn more about how national vaccination programmes are implemented, whether recommended or mandatory. Information was collected from all 27 EU Member States, Iceland and Norway. In total 15 countries do not have any mandatory vaccinations; the remaining 14 have at least one mandatory vaccination included in their programme. Vaccination against polio is mandatory for both children and adults in 12 countries; diphtheria and tetanus vaccination in 11 countries and hepatitis B vaccination in 10 countries. For eight of the 15 vaccines considered, some countries have a mixed strategy of recommended and mandatory vaccinations. Mandatory vaccination may be considered as a way of improving compliance to vaccination programmes. However, compliance with many programmes in Europe is high, using only recommendations. More information about the diversity in vaccine offer at European level may help countries to adapt vaccination strategies based on the experience of other countries. However, any proposal on vaccine strategies should be developed taking into consideration the local context habits.

Assessing the level of public health partner spending using the funding formula analysis tool.

Public health services are delivered through a variety of organizations. Traditional accounting of public health expenditures typically captures only spending by government agencies. New Hampshire collected information from public health partners, such as community centers that host smoking cessation classes or health education done by Girls, Inc. This study compares the new data to spending by government agencies, focusing on breakdowns by fund source and service categories. Expanded funds secured by these partners account for a 42% of all local public health spending, and they spent 4 times more than government agencies on promoting healthy behavior. The funding formula analysis tool revealed that these partners spent in ways that would be politically difficult to achieve. In an era of declining budgets, an understanding of public health's partners is increasingly vital.

Exploring Thailand's mortality transition with the aid of life tables.

The project Thai Health-Risk Transition: A National Cohort Study seeks to better understand the health implications of modernisation and globalisation forces impacting on Thailand. As part of its "look-back" component this paper seeks, using available life tables, to document the country's post-war mortality transition. The onset of transition through mass campaigns of the late 1940s and 1950s is first discussed before attention turns to the life tables. They are predictably far from flawless, but careful analysis does permit trends that have seen around 30 years added to life expectancy to be traced, and age patterns of improved survivorship and their relation to initiatives to improve health to be examined. The broad benefits generated by mass campaigns, ongoing improvements in infant and early childhood mortality, and a phased impact of the expansion of primary health care in rural areas on adult survival prospects after the mid-1970s are demonstrated. The paper also investigates the consequences for mortality of a motorcycle-focused rapid increase in road fatalities in the late 1980s and early 1990s and the HIV/AIDS epidemic that developed after 1984.

HIV/AIDS information by African companies: an empirical analysis.

This article investigates the extent of Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome Disclosures (HIV/AIDSD) in online annual reports by 200 listed companies from 10 African countries for the year ending 2006. Descriptive statistics reveal a very low level of overall HIV/AIDSD practices with a mean of 6 per cent disclosure, with half (100 out of 200) of the African companies making no disclosures at all. Logistic regression analysis reveals that company size and country are highly significant predictors of any disclosure of HIV/AIDS in annual reports. Profitability is also statistically significantly associated with the extent of disclosure.

Social will for tobacco control among the Hungarian public health workforce.

BACKGROUND: More than 1 in 5 deaths in Hungary can be attributed to tobacco smoking. The role of the public health agency in responding to and ameliorating the tobacco epidemic in Hungary has been, until now, unexplored. This paper explores the social will of the public health agency workers to adopt tobacco control measures. METHODS: 269 Hungarian public health workers throughout Hungary completed an electronic survey on the types of programs offered by the public health agency, the perceived level of responsibility to reduce tobacco use, and the social will of the agencies to curb tobacco use. Multivariate analyses were performed to estimate factors which contribute to the social will to curb tobacco use. RESULTS: 48% of public health workers in Hungary report that it is absolutely important for local public health agencies to offer tobacco prevention and cessation programs, but only 3% indicate that they have earmarked funds to support anti-tobacco programs. Most workers favor more programs and policies to curb tobacco use in Hungary, such as taxation (67%) and banning smoking in restaurants (81%) and confined sporting events (93%). Factors positively associated with a stronger social will for tobacco control included being a former or never smoker (versus a current smoker) (p < 0.001) and being middle age (40-49, p = 0.04 and 50-59, p = 0.01) (versus being under the age of 30). CONCLUSION: Based on a SWOT (strengths, weaknesses, opportunities and threats) analyses, we argue that public health workers have the potential to play an important role in disseminating health promotion programs and advocating for broader statewide policies that could reduce tobacco use and exposure to environmental tobacco smoke. However, such an opportunity is missed with neither designated funding nor a nationally-dedicated office to tobacco control in Hungary.

Vasectomy within the public health services in Campinas, São Paulo, Brazil.

OBJECTIVE: To describe some of the characteristics of men who underwent a vasectomy in the public health network of Campinas, São Paulo, Brazil. METHODS: A descriptive study including 202 men randomly selected from a list of all the men vasectomized between 1998 and 2004 in the public health network. RESULTS: Most of the men were 30 years of age or older when vasectomized, had completed elementary school and had two or more children of both sexes. Most of the men came from the lowest income segment of the population: 47.6% in 1998-1999 and 61.3% in 2003-2004. Although the men knew various contraceptive methods, 51.2% reported that their partners were using combined oral contraceptives at the time of surgery. Most men initially sought information on vasectomy at health-care clinics where care was provided by a multidisciplinary team; most received counselling, however, 47.9% of the men waited more than 4 months for the vasectomy. CONCLUSIONS: The profile of the vasectomized men in this study appears to indicate that the low-income population from Campinas, São Paulo, Brazil has access to vasectomy; however, the waiting time for vasectomy reveals that difficulties exist in obtaining this contraceptive method in the public health service.

Are cancer registries unconstitutional?

Population-based cancer registration, mandated throughout the United States, is central to quantifying the breadth and impact of cancer. It facilitates research to learn what causes cancer to develop and, in many cases, lead to death. However, as concerns about privacy increase, cancer registration has come under question. Recently, its constitutionality was challenged on the basis of 1) the vagueness of statutory aims to pursue public health versus the individual privacy interests of cancer patients, and 2) the alleged indignity of one's individual medical information being transmitted to government authorities. Examining cancer registry statutes in states covered by the US National Cancer Institute's SEER Program and the US Centers for Disease Control and Prevention's National Program of Cancer Registries, we found that cancer registration laws do state specific public health benefits, and offer reasonable limits and safeguards on the government's possession of private medical information. Thus, we argue that cancer registration would survive constitutional review, is compatible with the civil liberties protected by privacy rights in the U.S., satisfies the conditions that justify public health expenditures, and serves human rights to enjoy the highest attainable standards of health, the advances of science, and the benefits of government efforts to prevent and control disease.

Public health management of perinatal hepatitis B virus.

Infants who are born to hepatitis B surface antigen (HbsAg)-positive women are at high risk for contracting perinatal hepatitis B virus (HBV) infection. When maternal status is known, postexposure prophylaxis (PEP) consisting of a birth dose of (HBV) vaccine and Hepatitis B Immune Globulin may be administered within 12 hr of birth to provide 90% protection. Providers' reporting of maternal HBsAg positivity or perinatal HBV should prompt public health nurses to initiate nurse case management (NCM). NCM is the most successful way to ensure that at-risk infants receive PEP and follow-up serology. Unfortunately, reporting laws vary greatly by state and the Centers for Disease Control and Prevention estimate that perinatal HBV is significantly under-reported nationally. This article discusses public health measures for preventing perinatal HBV and presents a case study that used a novel method to assess the extent of under-reporting. We discuss barriers to public health NCM and the importance of a universal HBV vaccine birth dose to protect undetected and unreported cases. Finally, we suggest implications for public health nursing practice.

A broader liberty: J.S. Mill, paternalism and the public's health.

Is the 'harm principle', famously propounded by J.S. Mill and widely adopted in bioethics, an appropriate principle to guide public health regulation? The harm principle limits liberty-limiting interventions to those instances where the person poses a significant risk of harm to others. However, much of public health regulation is not primarily directed to avert risk to others, but to safeguard the health and safety of the individual him- or herself. Regulations regarding seatbelts, motorcycle helmets and the fluoridation of water are examples of pervasive public health regulations that are primarily intended to safeguard the individual's own health or safety. Even laws designed to reduce smoking are justified, at least in substantial part, by the reduction of risk to the smoker. Certainly, scholars argue that there are 'other-regarding' aspects to these types of laws, but there is little doubt that there are strong paternalistic features to these, and many other public health laws, such as bans on trans fat in foods. This article directly and forcefully questions the Millian principle, making the case for hard paternalism. When seen from a population-based perspective that counts the number of lives saved, paternalism becomes a plausible justification for interventions that do not pose a truly significant burden on individual liberty, but go a long way towards safeguarding the health and well-being of the populace.

Manhattan transfer: lethal radiation, bone marrow transplantation, and the birth of stem cell biology, ca. 1942-1961.

This study investigates how, in the late 1940s and 1950s, fears of nuclear accidents and nuclear warfare shaped postwar radiobiology. The new and intense forms of radiation generated by nuclear reactor technology, and which would be released in the event of a nuclear war, created concerns about a public-health hazard unprecedented in form and scale. Fears of inadvertent exposure to acute and potentially lethal radiation launched a search for anti-radiation therapies, out of which emerged the new technique of bone marrow transplantation (BMT). This study analyzes the use of BMT first as a research tool to explore the biological effects of ionizing radiation, and then as an adjunct to radiotherapy for the treatment of cancer. In highlighting how BMT became the province of different research and clinical constituencies, this study develops an understanding of the forces and contingencies that shaped its development. Exploring the emergence of BMT and the uses to which it was put, it reveals that BMT remained a technique in the making -- unstable and far from standardized, even as it became both a widely used research tool and rapidly made its way into the clinic. More broadly, it casts new light on one route through which the Manhattan Project influenced postwar radiobiology; it also affords new insights into one means by which radiobiology came to serve the interests of the Cold War state. In its focus on BMT this paper provides a new perspective on the evolving relationship between radiobiology and biomedicine in the postwar period.
