Supreme Court v. Necropolitics: The Chaotic Judicialization of COVID-19 in Brazil.

Worldwide, governments have reacted to the COVID-19 pandemic with emergency orders and policies restricting rights to movement, assembly, and education that have impacted daily lives and livelihoods in profound ways. But some leaders, such as President Jair Bolsonaro in Brazil, have resisted taking such steps, denying the seriousness of the pandemic and sabotaging local control measures, thereby compromising population health. Facing one of the world's highest rates of COVID-19 infections and deaths, multiple political actors in Brazil have resorted to judicialization to advance the right to health and other protections in the country. Responding to this litigation has provided the country's Supreme Court an opportunity to assertively confront and counter the executive's necropolitics. In this article, we probe the malleable form and the constitutional basis of the Supreme Court's decisions, assessing their impact on the separation of powers, on the protection of human rights (for example, on those of prisoners, indigenous peoples, and essential workers), and relative to the implementation of evidence-based interventions (for example, lockdowns and vaccination). While the court's actions open up a distinct legal-political field (sometimes called "supremocracy")-oscillating between progressive imperatives, neoliberal valuations, and conservative decisions-the capacity of the judiciary to significantly address systemic violence and to robustly advance human rights remains to be seen.

Assessing the short-run effects of lockdown policies on economic activity, with an application to the Santiago Metropolitan Region, Chile.

This paper develops a methodology for the assessment of the short-run effects of lockdown policies on economic activity. The methodology combines labor market data with simulation of an agent-based model. We apply our methodology to the Santiago Metropolitan Region, Chile. We recover the model parameters from observed data, taking into account the recurring policy adjustments that characterized the study window. The model is used to build counterfactual scenarios. We estimate an 8 percent output loss in the first 5 months of the pandemic from the policy that was put in place, achieving a 56 percent reduction in the total number of infections. During this period, with an output loss to 10.5 percent of GDP, the infection rate would have decreased 92 percent, significantly delaying the spread of COVID and spike in infections. Our methodology applied to real data provided results that could be valuable in guiding policies in other lockdown situations in times of disaster, pandemics or social upheaval.

Assessing the nationwide impact of COVID-19 mitigation policies on the transmission rate of SARS-CoV-2 in Brazil.

COVID-19 is now identified in almost all countries in the world, with poorer regions being particularly more disadvantaged to efficiently mitigate the impacts of the pandemic. In the absence of efficient therapeutics or large-scale vaccination, control strategies are currently based on non-pharmaceutical interventions, comprising changes in population behavior and governmental interventions, among which the prohibition of mass gatherings, closure of non-essential establishments, quarantine and movement restrictions. In this work we analyzed the effects of 707 governmental interventions published up to May 22, 2020, and population adherence thereof, on the dynamics of COVID-19 cases across all 27 Brazilian states, with emphasis on state capitals and remaining inland cities. A generalized SEIR (Susceptible, Exposed, Infected and Removed) model with a time-varying transmission rate (TR), that considers transmission by asymptomatic individuals, is presented. We analyze the effect of both the extent of enforced measures across Brazilian states and population movement on the changes in the TR and effective reproduction number. The social mobility reduction index, a measure of population movement, together with the stringency index, adapted to incorporate the degree of restrictions imposed by governmental regulations, were used in conjunction to quantify and compare the effects of varying degrees of policy strictness across Brazilian states. Our results show that population adherence to social distance recommendations plays an important role for the effectiveness of interventions and represents a major challenge to the control of COVID-19 in low- and middle-income countries.

Lifting mobility restrictions and the effect of superspreading events on the short-term dynamics of COVID-19.

SARS-CoV-2 has now infected 15 million people and produced more than six hundred thousand deaths around the world. Due to high transmission levels, many governments implemented social distancing and confinement measures with different levels of required compliance to mitigate the COVID-19 epidemic. In several countries, these measures were effective, and it was possible to flatten the epidemic curve and control it. In others, this objective was not or has not been achieved. In far too many cities around the world, rebounds of the epidemic are occurring or, in others, plateaulike states have appeared, where high incidence rates remain constant for relatively long periods of time. Nonetheless, faced with the challenge of urgent social need to reactivate their economies, many countries have decided to lift mitigation measures at times of high incidence. In this paper, we use a mathematical model to characterize the impact of short duration transmission events within the confinement period previous but close to the epidemic peak. The model also describes the possible consequences on the disease dynamics after mitigation measures are lifted. We use Mexico City as a case study. The results show that events of high mobility may produce either a later higher peak, a long plateau with relatively constant but high incidence or the same peak as in the original baseline epidemic curve, but with a post-peak interval of slower decay. Finally, we also show the importance of carefully timing the lifting of mitigation measures. If this occurs during a period of high incidence, then the disease transmission will rapidly increase, unless the effective contact rate keeps decreasing, which will be very difficult to achieve once the population is released.

UNIVERSAL MASKING DURING COVID-19 PANDEMIC - CURRENT EVIDENCE AND CONTROVERSIES.

The emergence of coronavirus disease 19 pandemic and novel research on the high transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has raised controversies over the use of face masks to prevent community transmission. Specific regulations need to be fulfilled to use a face mask as part of the personal protective equipment and high quality of evidence supporting its use to prevent respiratory viral infections, including SARS-CoV-2, is lacking. However, its widespread use is becoming a standard practice in some countries and discrepancies between health authorities on their policy have led to controversy. The aim of this review is to provide an outlook on recent research in this matter and areas of opportunity.

Declaración del Comité Consultivo de Inmunizaciones de Sociedad Chilena de Infectología en relación a los cuestionamientos de las vacunas y su obligatoriedad / Statement from the Immunization Committee of the Chilean Infectious Diseases Society in reference to vaccine refusal and mandatory policy on vaccination

Resumen A pesar del enorme impacto de las vacunas en la salud de la población, éstas han sido y son objeto de cuestionamientos por grupos que las consideran innecesarias o inseguras y argumentan que las personas tienen el derecho a decidir sobre si éstas deben ser administradas o no. Sin embargo, el uso de vacunas tiene connotaciones distintas a otras decisiones en salud, ya que no vacunar impacta no sólo al individuo, sino también a la comunidad que lo rodea. El inmunizar a un alto porcentaje de la población permite limitar la circulación de los agentes infecciosos, logrando la llamada inmunidad comunitaria que protege a los no vacunados por razones médicas o porque son muy pequeños. Por esta razón muchos países han definido las vacunas como obligatorias. Como Comité Consultivo de Inmunizaciones nos parece que esta estrategia es correcta; sin embargo, debe ser acompañada por una política de educación de la población y personal de salud sobre los beneficios y riesgos reales de las vacunas. Así mismo es necesario introducir mejoras en el sistema de notificación de reacciones adversas a vacunas haciéndolo más accesible. Adicionalmente, se debe dar respuesta oportuna a los afectados por supuestas o reales reacciones a vacunas, y en los casos de eventos adversos graves efectivamente asociados a vacunas. entregar cobertura económica y acompañamiento. Finalmente, es esencial la coordinación entre los diferentes actores y comunicadores para transmitir mensajes que generen confianza y respondan a las inquietudes de la población de hoy en día.

Although vaccines have had a tremendous impact in public health they are questioned by certain groups that consider them unnecessary or unsafe and argue in favor of the right to decide to be vaccinated or not. However vaccines must have special considerations because unlike other medical decisions, not vaccinating has consequences not only for the individual but also for other members of the community. Immunizing a high proportion of the population limits the circulation of an infectious agent attaining what is called herd immunity that protects the susceptible members of the group. For this reason many countries consider vaccination mandatory as a responsibility of every citizen. This committee agrees with this view but thinks other strategies should be implemented as well, such as special educational efforts for the public and parents addressing benefits and real risks of vaccinating. Also health care professionals should be trained in vaccines. The notification system for adverse events currently available should be improved and be more accessible. Persons truly affected by adverse events due to vaccination should receive on time responses and be offered psychological and financial support. Finally all stakeholders should make coordinated efforts to work together to deliver messages that answer concerns on vaccines and bring confidence back to the public.

Legal aspects of public health: difficulties in controlling vector-borne and zoonotic diseases in Brazil.

In recent years, vector-borne and zoonotic diseases have become a major challenge for public health. Dengue fever and leptospirosis are the most important communicable diseases in Brazil based on their prevalence and the healthy life years lost from disability. The primary strategy for preventing human exposure to these diseases is effective insect and rodent control in and around the home. However, health authorities have difficulties in controlling vector-borne and zoonotic diseases because residents often refuse access to their homes. This study discusses aspects related to the activities performed by Brazilian health authorities to combat vector-borne and zoonotic diseases, particularly difficulties in relation to the legal aspect, which often impede the quick and effective actions of these professionals. How might it be possible to reconcile the need to preserve public health and the rule on the inviolability of the home, especially in the case of abandoned properties or illegal residents and the refusal of residents to allow the health authority access? Do residents have the right to hinder the performance of health workers even in the face of a significant and visible focus of disease transmission? This paper argues that a comprehensive legal plan aimed at the control of invasive vector-borne and zoonotic diseases including synanthropic animals of public health importance should be considered. In addition, this paper aims to bridge the gap between lawyers and public health professionals and to facilitate communication between them.

The production of social discourse on Hansen' disease and health education materials in Brazil: a skin patch as something harmless or a serious disease?

AIMS: Hansen's disease is endemic in Brazil and government control programmes promote publicity campaigns to increase the detection of new cases through the production and distribution of educative material. OBJECTIVES: This study analyses a set of 276 educational materials produced by governmental and non-governmental organisations that work to control Hansen's disease in Brazil. It describes the content of the materials and the way the issues were approached. DESIGN: It is a qualitative study that adopts the theoretical and methodological framework of the semiology of social discourse. RESULTS: Analysis reveals that the relations between the enunciator and recipient of the materials are asymmetrical as a result of the technical and educational language employed. Biomedical information forms the basis for social representations an practices of Hansen's disease, as opposed to historical collective knowledge of 'leprosy'. The prioritised topics are: signs and symptoms of the disease, treatment stigma, cure and surveillance. CONCLUSIONS: The institutionalisation of public education on Hansen's disease in Brazil was not limited simply to the change of terminology from 'leprosy' to 'Hansen's disease,' but was shaped also by new educational practices. It is recommended that the evaluation and production of new materials be incorporated into the set of activities already carried out in health centres so as to expand the discussion on content, language and the best way to address the disease in the materials.

Epidemiology and prevention of meningococcal disease: a critical appraisal of vaccine policies.

Meningococcal disease is characterized by a marked variation in incidence and serogroup distribution by region and over time. In several European countries, Canada and Australia, immunization programs, including universal vaccination of infants or toddlers with catch-up campaigns in children and adolescents, aimed at controlling disease caused by meningococcal serogroup C have been successful in reducing disease incidence through direct and indirect protection. More recently, meningococcal conjugate vaccines targeting disease caused by serogroups A, C, W-135 and Y have been licensed and are being used in adolescent programs in the USA and Canada while a mass immunization campaign against serogroup A disease has been implemented in Africa. Positive results from clinical trials using vaccines against serogroup B disease in various age groups suggest the possibility of providing broader protection against serogroup B disease than is provided by the currently used outer membrane vesicle vaccines. The purpose of our review of meningococcal epidemiology and assessment of existing policies is to set the stage for future policy decisions. Vaccination policies to prevent meningococcal disease in different regions of the world should be based on quality information from enhanced surveillance systems.

An analysis of the 1978 African swine fever outbreak in Brazil and its eradication.

The aim of this paper is to evaluate the African swine fever (ASF) outbreak that began in 1978 in Paracambi municipality, Rio de Janeiro State, Brazil, and the steps taken by the Brazilian authorities to eradicate the disease. The presence of ASF in the country was confirmed by isolating the virus, and its pathogenicity was certified by the laboratory of the Plum Island Disease Center, New York, United States. Even before the laboratory results became available, the Brazilian Agriculture Ministry declared an Animal Health Emergency, in which the official Veterinary Services adopted rapid control measures to restrain and eradicate the disease. These control measures contributed to the reorganisation of the national swine industry and stimulated the use of high-technology production techniques, as well as an improvement in herd health consciousness. All this contributed to Brazil becoming the largest meat exporter in the world.
