Ethical and Practical Considerations for an Agreement to Ensure Equitable Vaccine Access Comment on "More Pain, More Gain! The Delivery of COVID-19 Vaccines and the Pharmaceutical Industry's Role in Widening the Access Gap".

This paper discusses the potential of an international agreement to ensure equitable vaccine distribution, addressing the failures witnessed during the COVID-19 pandemic. COVAX was unable to prevent vaccine monopolization and unequal distribution, which led to significant disparities in vaccination rates and avoidable deaths. Any future agreement on equitable vaccine distribution must address ethical and practical issues to ensure global health equity and access. The proposed agreement should recognize healthcare as a human right and consider vaccines beyond mere commodities, emphasizing the social responsibility of pharmaceutical companies to prioritize affordability, availability, and accessibility, particularly for low-income countries (LICs). Voluntary licensing agreements are suggested as a means to enhance access to essential medicines. The paper also outlines the necessity of international cooperation, with robust compliance mechanisms, to effectively enforce such an agreement and mitigate future health crises.

Preparing for the next respiratory pathogen pandemic: using tabletop simulation exercises to strengthen national planning in Cook Islands, Costa Rica, Lebanon and Mongolia.

The Preparedness and Resilience for Emerging Threats (PRET) initiative takes an innovative mode-of-transmission approach to pandemic planning by advocating for integrated preparedness and response systems and capacities for groups of pathogens with common transmission pathways. The World Health Organization (WHO) launched this initiative in 2023 with the publication of PRET Module 1 addressing respiratory pathogens. Exercise PanPRET-1 is a customizable tabletop simulation exercise (TTX) package developed to complement PRET Module 1. The exercise scenario focuses on strengthening capacities for multisectoral coordination, risk communication and community engagement, and the triggers for operational decision-making. This article reports on the experiences of the first four countries to implement Exercise PanPRET-1: Cook Islands, Costa Rica, Lebanon and Mongolia. Exercise outcomes demonstrated that PanPRET-1 can be an effective tool for testing pandemic plans in a multisectoral forum and identifying opportunities to improve preparedness and response in key domains. In quantitative evaluations in Cook Islands, Costa Rica and Mongolia, high proportions of exercise participants indicated that multiple aspects of the exercise were well-designed and were beneficial for improving health emergency preparedness. Exercise participants in Lebanon provided qualitative feedback indicating that they found the exercise to be beneficial. Conducting a TTX and monitoring the implementation of action plans based on exercise findings facilitates a country-owned whole-of-society vision for pandemic planning. Countries are encouraged to incorporate TTX such as Exercise PanPRET-1 into a continuous cycle of activity to improve pandemic preparedness.

The Importance of Networks and Relationships: Leveraging the Biocontainment Unit Leadership Workgroup for Special Pathogen Outbreak Response.

Developing and sustaining relationships and networks before an emergency occurs is crucial. The Biocontainment Unit Leadership Workgroup is a consortium of the 13 Regional Emerging Special Pathogen Treatment Centers in the United States. Established in 2017, the volunteer-based workgroup is composed of operational leaders dedicated to maintaining readiness for special pathogen care. Monthly meetings focus on addressing operational challenges, sharing best practices, and brainstorming solutions to common problems. Task forces are leveraged to tackle more complex issues that are identified as priorities. In 2022, members of the workgroup were harnessed for response efforts related to mpox, Sudan ebolavirus, and Marburg virus disease. The weekly Outbreak Readiness call is a shared effort between the Biocontainment Unit Leadership Workgroup and the Special Pathogens Research Network of the National Emerging Special Pathogens Training and Education Center. Call participants included leaders of the Regional Emerging Special Pathogen Treatment Centers and federal partners who shared weekly updates on operational readiness of units, case counts, laboratory capacity, available medical countermeasures, and other pertinent information. The routine exchange of real-time information enabled learning and collegial sharing of experiences, highlighted the experience of the network to federal partners, and provided situational awareness of special pathogen outbreaks across the country. The consortium enabled this rapid convening of partners to meet an urgent need for special pathogen response. The weekly Outbreak Readiness call is a communication model and scalable framework that serves both domestic preparedness efforts and international efforts should the need for a collaborative global response arise. In this case study, we describe the framework and experience of this partnership, along with the structure of rapid deployment for group convening.

Preparing for Cancer: A Qualitative Study of Hispanic Patient and Caregiver Needs.

BACKGROUND: Cancer disproportionately affects Hispanic populations, yet the preparedness of Hispanic caregiver-patient dyads facing cancer remains understudied. This study aims to identify essential components of preparedness needs and inform future psychosocial interventions for this demographic. METHODS: Secondary analyses were conducted utilizing focus groups to develop a communication intervention for Hispanic patients and caregivers. Transcripts were qualitatively analyzed using NVivo v12 (2020). RESULTS: Analysis revealed symptom management and treatment comprehension as pivotal aspects of preparation. Additionally, preparedness among our sample emerged by addressing the multifaceted dimensions of preparedness, including psychological, emotional, educational, familial, practical, financial, and spiritual aspects. CONCLUSIONS: Tailoring interventions encompassing diverse dimensions of preparedness can foster inclusivity and maximize their impact on supportive measures. This underscores the necessity for culturally sensitive approaches when delivering interventions supporting Hispanic individuals navigating the challenges of cancer.

The lived experiences and perceptions of middle-aged adults in Dominica who have survived severe storms-a qualitative exploration.

Introduction: The Eastern Caribbean island of Dominica has experienced diverse negative effects from the North Atlantic hurricane season, including deadly storms like Hurricane Maria in 2017. Vulnerability is increased by geographic location, small island developing state (SIDS) status, and ecosystem characteristics. A variety of negative health effects including stress and anxiety are caused by powerful storms. The perspectives of middle-aged (the "sandwich generation") survivors in this post-storm milieu are understudied. Methods: This phenomenological qualitative study describes the perceptions of middle-aged (35-55 years) Dominicans, purposively recruited with gatekeeper assistance from communities stratified according to four natural hazard vulnerability categories designated by the Climate Resilience Execution Agency for Dominica (CREAD), regarding their lived experiences in the context of severe storms. Data was collected between June and August 2022, using primarily Zoom-based semi-structured, individual interviews (12 of 13), guided by the principles of saturation and maximum variation. Verbatim interview transcripts were thematically analyzed with constant comparison using an ATLAS.ti-supported hybrid deductive-inductive coding frame. Reflexivity and contact summary sheets were used to minimize bias. Results: Ten women and three men from diverse CREAD vulnerability and sociodemographic backgrounds were recruited. Data condensation yielded three organizing themes: (i) "The diverse health effects of severe storms", (ii) "Response to and recovery from severe storms", and (iii) "Preparedness and precaution for severe storms". These themes encapsulated the health impacts of severe storms on Dominicans and elucidated the role of facilitating and barricading resilience factors. Discussion: Severe storms produced direct and indirect mental, social, and physical health impacts on middle-aged Dominicans, including anxiety and burnout. Participants used faith-based, tangible community-based support, and emotional mechanisms to cope with and demonstrate resilience. Better risk communication and early warning systems would improve population readiness. Persistent dispirited attitudes toward storm preparedness among some participants suggest the need for targeted methods to enhance community involvement in disaster planning, including traditional approaches like "coup-de-main" (self-help).

Preparing for future pandemics while responding to the current ones in the midst of a planetary climate crisis: Can we face this triple global health challenge?

Global health faces the triple challenge of preparing for future pandemics while responding to current ones in the midst of a climate crisis. In this commentary, we discuss the heightened focus on pandemic preparedness after the COVID-19 pandemic and the risks that this may pose to addressing the elimination of AIDS, tuberculosis, hepatitis and malaria, established in the Sustainable Development Goals as target 3.3. Considering their interconnections with the climate crisis and advocating for global health justice, we identify impasses that such a dispute over priorities can imply, and comment on four fronts of actions that could contribute convergently to both agendas as well as to facing the consequences of climate change to health: strengthening health systems, global commitment to equitable access to strategic medicines, addressing social inequalities and joining efforts for health and climate justice We conclude that addressing these fronts safeguards the health rights of the most vulnerable to existing epidemics while enhancing readiness for future pandemics. Moreover, solutions must transcend technocratic approaches, necessitating the confrontation of inequalities perpetuated by systems of power and privilege fueling both health and climate crises. Ultimately, health justice should guide responses to this intricate triple global health challenge.

Capacity of community health centers to treat snakebite envenoming in indigenous territories of the Brazilian Amazon.

INTRODUCTION: The deaths from and morbidities associated with snakebites - amputations, loss of function in the limb, visible scarring or tissue damage - have a vast economic, social, and psychological impact on indigenous communities in the Brazilian Amazon, especially children, and represent a real and pressing health crisis in this population. Snakebite clinical and research experts have therefore proposed expanding antivenom access from only hospitals to include the community health centers (CHC) located near and within indigenous communities. However, there are no studies examining the capacity of CHCs to store, administer, and manage antivenom treatment. In response to this gap, the research team calling for antivenom decentralization developed and validated an expert-based checklist outlining the minimum requirements for a CHC to provide antivenom. METHODS: The objective of this study was thus to survey a sample of CHCs in indigenous territories and evaluate their capacity to provide antivenom treatment according to this accredited checklist. The checklist was administered to nurses and doctors from 16 CHCs, two per indigenous district in Amazonas/Roraima states. RESULTS: Our results can be conceptualized into three central findings: 1) most CHCs have the capacity to provide antivenom treatment, 2) challenges to capacity are human resources and specialized items, and 3) antivenom decentralization is feasible and appropriate in indigenous communities. CONCLUSION: Decentralization would provide culturally and contextually appropriate care accessibility to a historically marginalized and underserved population of the Brazilian Amazon. Future studies should examine optimal resource allocation in indigenous territories and develop an implementation strategy in partnership with indigenous leaders. Beyond the indigenous population, the checklist utilized could be applied to community health centers treating the general population and/or adapted to other low-resource settings.

Emergency preparedness and response sensitive of migrant populations in Chile: post-pandemic perspectives. / Preparación y respuesta ante emergencias sensibles a poblaciones migrantes en Chile: perspectivas postpandémicas.

On August 31, 2023, the Chilean government ended the health alert for COVID-19. This milestone invites us to reflect on lessons learned in emergency preparedness and response regarding migrant populations in the country. In this context, three perspectives are presented. The first focuses on avoiding pointing to individual responsibility for non-compliance with prevention measures, as this approach ignores structural and historical inequities. Emergency recommendations should be constructed considering a collective approach and diverse sociocultural and political contexts. The second perspective calls for considering and addressing migration as a social determinant of health. During the pandemic, changes in the governance of migration around the world made migration processes more precarious, with risks to the physical and mental health of migrants, which needs better planning and evidence-based decision-making in future pandemics. The third perspective focuses on promoting intercultural health, as effective communication of contagion risks and preventive measures were hampered among migrant populations with diverse worldviews and interpretations of health and disease processes. Responding to the needs of historically marginalized communities requires establishing ways of life that respect diversity in narratives and everyday practices. Governments and health systems must incorporate migration into their emergency preparedness and response strategies, creating the conditions for optimal compliance.

El 31 de agosto de 2023, el Gobierno de Chile puso fin a la alerta sanitaria por COVID-19. Este hito invita a reflexionar sobre lecciones aprendidas respecto a la preparación y respuesta ante emergencias, que sean sensibles e informadas sobre la experiencia de la población migrante de nuestro país. En este marco, se presentan tres perspectivas. La primera se centra en evitar la responsabilización individual en el incumplimiento de las medidas de prevención del contagio, ya que este enfoque ignora las inequidades estructurales e históricas. Las recomendaciones de emergencia se deben construir bajo un abordaje colectivo y con la consideración de los diversos contextos socioculturales y políticos. La segunda perspectiva llama a tomar en cuenta y abordar la migración como determinante social de la salud de la población en la preparación y respuesta ante emergencias. Durante la pandemia, los cambios en la gobernanza de la migración en todo el mundo precarizaron los procesos migratorios, con riesgos para la salud física y mental de las personas que migran. Esto requiere una mejor planificación y decisiones informadas en evidencia científica para futuras pandemias. La tercera perspectiva se enfoca en promover la interculturalidad, dado que la comunicación de los riesgos de contagio y de las medidas preventivas se vio dificultada entre poblaciones migrantes con diversas cosmovisiones e interpretaciones de los procesos de salud y enfermedad. Asimismo, el responder a las necesidades de aquellas comunidades históricamente marginadas, requiere establecer modos de vida que respeten la diversidad en las narrativas y las prácticas cotidianas. Los gobiernos y sistemas sanitarios deben incorporar la migración a sus estrategias de preparación y respuesta ante emergencias, con la construcción de las condiciones para su cumplimiento óptimo.

Balancing the benefits of vaccination: An envy-free strategy.

The Covid-19 pandemic revealed the difficulties of vaccinating a population under the circumstances marked by urgency and limited availability of doses while balancing benefits associated with distinct guidelines satisfying specific ethical criteria. We offer a vaccination strategy that may be useful in this regard. It relies on the mathematical concept of envy-freeness. We consider finding balance by allocating the resource among individuals that seem heterogeneous concerning the direct and indirect benefits of vaccination, depending on age. The proposed strategy adapts a constructive approach in the literature based on Sperner's Lemma to point out an approximate division of doses guaranteeing that both benefits are optimized each time a batch becomes available. Applications using data about population age distributions from diverse countries suggest that, among other features, this strategy maintains the desired balance, throughout the entire vaccination period. We discuss complementary aspects of the method in the context of epidemiological models of age-stratified Susceptible - Infected - Recovered (SIR) type.

Perceptions of the Zika Virus, Contraceptive Access, and Motivation to Participate in the Zika Contraception Access Network Program: Qualitative Analysis of Focusgroup Discussions with Puerto Rican Women.

OBJECTIVE: During the 2016-2017 Zika virus outbreak in Puerto Rico, the Zika Contraception Access Network (Z-CAN) provided client-centered contraceptive counseling and access to the full range of reversible contraceptive methods at no cost to prevent unintended pregnancies and thereby to reduce Zika-related birth outcomes. METHODS: To understand how Puerto Rican women's perceptions of the Zika virus affected contraceptive decisions and assess how they heard about the Z-CAN program and what influenced their participation, or lack thereof, 24 focus-group discussions were conducted among women of reproductive age who did and did not participate in Z-CAN. RESULTS: Women who participated in the discussions often had heard about Z-CAN from their physician or friends; non-participants had heard about Z-CAN from Facebook or friends. Women expressed satisfaction on finding a Z-CAN clinic and valued the same-day provision of contraceptives. When a preferred contraceptive method or a first appointment was not readily available, women reconsidered accessing the program. Women's perceptions and trust of reproductive healthcare providers, their engagement in social networks, and their ability to choose a contraceptive method that best meets their needs can influence participation in contraception-access programs. CONCLUSION: Focus groups can be used to understand women's knowledge of the Zika virus, barriers and facilitators to contraception access, and motivations for participation in the Z-CAN program.

Research methods challenges: A case study of preparedness in The Bahamas.

Disaster research is essential for developing more robust and contextualised policies. It is, therefore, no surprise that multilateral organisations like the United Nations and the World Bank have called for enhanced disaster-related frameworks, legislation and policies in developing countries using quality data. However, internal and external researchers and practitioners often face significant challenges collecting data in these nations because of a range of problems including, but not limited to, incomplete sampling frames, inadequate infrastructure or unstable governments. This reality leads one to question: is the cart coming before the horse? This study explored individual and household (IH) preparedness in The Bahamas - a small island developing state in the Caribbean. An online survey was used, and 629 Bahamians opted to participate. However, the researchers faced many barriers to collecting representative data. This case study, therefore, discusses the range of methodological challenges faced by the researchers and their impact on this study. Contribution: This article substantially contributes to the disaster literature by exploring the challenges associated with conducting IH preparedness research in The Bahamas. This article also reminds practitioners and academics of the issues associated with collecting data in developing nations and its implications for policy enhancement and development. Furthermore, the authors present various recommendations ranging from enhanced funding to recognising the need for methodological innovation to support continuous research in countries like The Bahamas.

Profile, performance, and perception of pharmacist preparedness for the COVID-19 pandemic.

INTRODUCTION: The lack of human resources for disease prevention and control is evident in times of health crisis, such as the COVID-19 pandemic. In public health emergencies, the capacity for adequate assistance and guaranteed access to pharmacological treatment are fundamental and contribute to impact reduction. We aimed to analyze the profile, performance, and characteristics related to the self-perception of preparedness among pharmacists who responded to the COVID-19 pandemic in Brazil. METHOD: A cross-sectional study was conducted in two stages: content validation of a questionnaire and its application to a representative sample of pharmacists in Rio de Janeiro. The snowball technique was used to recruit participants. A logistic regression model was adjusted to determine the effects of the factors on the probability of a pharmacist feeling prepared to act during the pandemic. RESULTS: Six experts approved and validated the questionnaire, and 376 pharmacists were included in the study, 60.6 % of whom were in places specially designated by health authorities to diagnose and treat COVID-19. Professionals participated in various activities related to pandemic demands, including medication management and population guidance. Postgraduate degrees increased the odds of participants feeling prepared to act during the pandemic. Furthermore, pharmacists who worked in reference facilities were more likely to feel ready than those who worked in other places. Professionals who knew treatment guidelines were almost three times more likely to feel prepared than the ones without the knowledge of treatment guidelines. Training or guidance on how to act during the pandemic increased pharmacists' odds of feeling prepared by 2.58 times. CONCLUSION: Pharmacists actuated from diagnosis to treatment and participated in the health activities required during the pandemic. Factors contributing to the self-perception of preparedness were identified. Such factors can be targets for interventions to promote the preparedness of the workforce for future health emergencies.

Earthquakes, Hurricanes, Pandemics: Pharmacy Students Impacting Pharmacy Practice in Puerto Rico Through Medication Therapy Management Services During Disasters.

BACKGROUND: Community-based medication therapy management advanced pharmacy practice experiences (MTM APPE) can engage pharmacy students in public health initiatives, including emergency response preparedness, to successfully impact patient care. This study aimed to evaluate pharmacy students' perceptions of their experience on an MTM APPE during disasters in Puerto Rico. METHODS: After completing the MTM APPE during times of hurricanes, earthquake or pandemic, pharmacy students were asked to voluntarily participate in a questionnaire about their perception of assisting during a disaster. The survey consisted of 5 questions. Four questions were based on a Likert scale with answers choices ranging from Agree, Not Sure, Disagree, or Not Applicable. One question requested free text comments from participants. RESULTS: Sixteen students completed the survey. Pharmacy students agreed that the MTM APPE taught them the clinical skills needed to assist and educate individual patients and the community that suffered from a disaster, and that the role of the pharmacist is vital when a disaster disrupts a community's health-care system. CONCLUSIONS: Training in emergency response to disasters should be a considered component of MTM APPE.

Promoting healthy populations as a pandemic preparedness strategy: a simulation study from Mexico.

Background: The underlying health status of populations was a major determinant of the impact of the COVID-19 pandemic, particularly obesity prevalence. Mexico was one of the most severely affected countries during the COVID-19 pandemic and its obesity prevalence is among the highest in the world. It is unknown by how much the COVID-19 burden could have been reduced if systemic actions had been implemented to reduce excess weight in Mexico before the onset of the pandemic. Methods: Using a dynamic epidemic model based on nationwide data, we compare actual deaths with those under hypothetical scenarios assuming a lower body mass index in the Mexican population, as observed historically. We also model the number of deaths that would have been averted due to earlier implementation of front-of-pack warning labels or due to increases in taxes on sugar-sweetened beverages and non-essential high-energy foods in Mexico. Findings: We estimate that 52.5% (95% prediction interval (PI) 43.2, 61.6%) of COVID-19 deaths were attributable to obesity for adults aged 20-64 and 23.8% (95% PI 18.7, 29.1%) for those aged 65 and over. Had the population BMI distribution remained as it was in 2000, 2006, or 2012, COVID-19 deaths would have been reduced by an expected 20.6% (95% PI 16.9, 24.6%), 9.9% (95% PI 7.3, 12.9%), or 6.9% (95% PI 4.5, 9.5%), respectively. If the food-labelling intervention introduced in 2020 had been introduced in 2018, an expected 6.2% (95% PI 5.2, 7.3%) of COVID-19 deaths would have been averted. If taxes on sugar-sweetened beverages and high-energy foods had been doubled, trebled, or quadrupled in 2018, COVID-19 deaths would have been reduced by an expected 4.1% (95% PI 2.5, 5.7%), 7.9% (95% PI 4.9, 11.0%), or 11.6% (95% PI 7.3, 15.8%), respectively. Interpretation: Public health interventions targeting underlying population health, including non-communicable chronic diseases, is a promising line of action for pandemic preparedness that should be included in all pandemic plans. Funding: This study received funding from Bloomberg Philanthropies, awarded to Juan A. Rivera from the National Institute of Public Health; Community Jameel, the UK Medical Research Council (MRC), Kenneth C Griffin, and the World Health Organization.

Combining Digital and Molecular Approaches Using Health and Alternate Data Sources in a Next-Generation Surveillance System for Anticipating Outbreaks of Pandemic Potential.

Globally, millions of lives are impacted every year by infectious diseases outbreaks. Comprehensive and innovative surveillance strategies aiming at early alert and timely containment of emerging and reemerging pathogens are a pressing priority. Shortcomings and delays in current pathogen surveillance practices further disturbed informing responses, interventions, and mitigation of recent pandemics, including H1N1 influenza and SARS-CoV-2. We present the design principles of the architecture for an early-alert surveillance system that leverages the vast available data landscape, including syndromic data from primary health care, drug sales, and rumors from the lay media and social media to identify areas with an increased number of cases of respiratory disease. In these potentially affected areas, an intensive and fast sample collection and advanced high-throughput genome sequencing analyses would inform on circulating known or novel pathogens by metagenomics-enabled pathogen characterization. Concurrently, the integration of bioclimatic and socioeconomic data, as well as transportation and mobility network data, into a data analytics platform, coupled with advanced mathematical modeling using artificial intelligence or machine learning, will enable more accurate estimation of outbreak spread risk. Such an approach aims to readily identify and characterize regions in the early stages of an outbreak development, as well as model risk and patterns of spread, informing targeted mitigation and control measures. A fully operational system must integrate diverse and robust data streams to translate data into actionable intelligence and actions, ultimately paving the way toward constructing next-generation surveillance systems.

The influence of risk awareness and government trust on risk perception and preparedness for natural hazards.

Risk perception is considered the primary motivator for taking preparedness actions. But people with prior experience and a high-risk perception are not necessarily more prepared. This relationship is even more complex when assessing preparedness levels for hazards with different characteristics. These inconsistent findings can be explained by how preparedness has been measured and the influence of other factors, such as trust and risk awareness. Thus, the main goal of this study was to analyze the role of risk awareness and trust in authorities on risk perception and intention to prepare for natural hazards in a coastal city in Chile. A representative sample of the city of Concepción, located in the center-south zone of Chile (n = 585), completed a survey. We measured risk awareness, risk perception, trust in authorities, and intention to prepare for two hazards: earthquakes/tsunamis and floods. Through structural equation models, we tested five hypotheses. We found that the perception of risk maintained a direct and positive influence on the intention to prepare for both hazards. The results showed that awareness and risk perception influence the intention to prepare and should be considered different concepts. Finally, trust did not significantly influence risk perception when faced with known hazards for the population. Implications for understanding the relationship between risk perception and direct experience are discussed.

Recent occurrence, diversity, and candidate vaccine virus selection for pandemic H5N1: alert Is in the air

The prevalence of the highly pathogenic avian influenza virus H5N1 in wild birds that migrate all over the world has resulted in the dissemination of this virus across Asia, Europe, Africa, North and South America, the Arctic continent, and Antarctica. So far, H5N1 clade 2.3.4.4.b has reached an almost global distribution, with the exception of Australia and New Zealand for autochthonous cases. H5N1 clade 2.3.4.4.b, derived from the broad-host-range A/Goose/Guangdong/1/96 (H5N1) lineage, has evolved, adapted, and spread to species other than birds, with potential mammal-to-mammal transmission. Many public health agencies consider H5N1 influenza a real pandemic threat. In this sense, we analyzed H5N1 hemagglutinin sequences from recent outbreaks in animals, clinical samples, antigenic prototypes of candidate vaccine viruses, and licensed human vaccines for H5N1 with the aim of shedding light on the development of an H5N1 vaccine suitable for a pandemic response, should one occur in the near future.

Capacity of community health centers to treat snakebite envenoming in indigenous territories of the Brazilian Amazon

Introduction The deaths from and morbidities associated with snakebites - amputations, loss of function in the limb, visible scarring or tissue damage - have a vast economic, social, and psychological impact on indigenous communities in the Brazilian Amazon, especially children, and represent a real and pressing health crisis in this population. Snakebite clinical and research experts have therefore proposed expanding antivenom access from only hospitals to include the community health centers (CHC) located near and within indigenous communities. However, there are no studies examining the capacity of CHCs to store, administer, and manage antivenom treatment. In response to this gap, the research team calling for antivenom decentralization developed and validated an expert-based checklist outlining the minimum requirements for a CHC to provide antivenom. Methods The objective of this study was thus to survey a sample of CHCs in indigenous territories and evaluate their capacity to provide antivenom treatment according to this accredited checklist. The checklist was administered to nurses and doctors from 16 CHCs, two per indigenous district in Amazonas/Roraima states. Results Our results can be conceptualized into three central findings: 1) most CHCs have the capacity to provide antivenom treatment, 2) challenges to capacity are human resources and specialized items, and 3) antivenom decentralization is feasible and appropriate in indigenous communities. Conclusion Decentralization would provide culturally and contextually appropriate care accessibility to a historically marginalized and underserved population of the Brazilian Amazon. Future studies should examine optimal resource allocation in indigenous territories and develop an implementation strategy in partnership with indigenous leaders. Beyond the indigenous population, the checklist utilized could be applied to community health centers treating the general population and/or adapted to other low-resource settings.

Assessing pandemic preparedness, response, and lessons learned from the COVID-19 pandemic in four south American countries: agenda for the future.

Introduction: The COVID-19 pandemic emerged in a context that lacked adequate prevention, preparedness, and response (PPR) activities, and global, regional, and national leadership. South American countries were among world's hardest hit by the pandemic, accounting for 10.1% of total cases and 20.1% of global deaths. Methods: This study explores how pandemic PPR were affected by political, socioeconomic, and health system contexts as well as how PPR may have shaped pandemic outcomes in Argentina, Brazil, Colombia, and Peru. We then identify lessons learned and advance an agenda for improving PPR capacity at regional and national levels. We do this through a mixed-methods sequential explanatory study in four South American countries based on structured interviews and focus groups with elite policy makers. Results: The results of our study demonstrate that structural and contextual barriers limited PPR activities at political, social, and economic levels in each country, as well as through the structure of the health care system. Respondents believe that top-level government officials had insufficient political will for prioritizing pandemic PPR and post-COVID-19 recovery programs within their countries' health agendas. Discussion: We recommend a regional COVID-19 task force, post-pandemic recovery, social and economic protection for vulnerable groups, improved primary health care and surveillance systems, risk communication strategies, and community engagement to place pandemic PPR on Argentina, Brazil, Colombia, and Peru and other South American countries' national public health agendas.
