Oropouche Fever, Cuba, May 2024.

Phylogenetic analyses showed that the virus responsible for a May 2024 Oropouche fever outbreak in Cuba was closely related to viruses from Brazil in 2023. Pools of Ceratopogonidae spp. biting midges and Culex quinquefasciatus mosquitoes were positive for Oropouche viral RNA. No cases were severe. Virus extension to new areas may increase case numbers and severity.

Replication-Competent Oropouche Virus in Semen of Traveler Returning to Italy from Cuba, 2024.

A febrile man in Italy who had traveled to Cuba in July 2024 was diagnosed with Oropouche fever. Reverse transcription PCR detected prolonged shedding of Oropouche virus RNA in whole blood, serum, urine, and semen. Sixteen days after symptom onset, replication-competent virus was detected in semen, suggesting risk for sexual transmission.

An island 'endemic' born out of hybridization between introduced lineages.

Humans have profoundly impacted the distribution of plant and animal species over thousands of years. The most direct example of these effects is human-mediated movement of individuals, either through translocation of individuals within their range or through the introduction of species to new habitats. While human involvement may be suspected in species with obvious range disjunctions, it can be difficult to detect natural versus human-mediated dispersal events for populations at the edge of a species' range, and this uncertainty muddles how we understand the evolutionary history of populations and broad biogeographical patterns. Studies combining genetic data with archaeological, linguistic and historical evidence have confirmed prehistoric examples of human-mediated dispersal; however, it is unclear whether these methods can disentangle recent dispersal events, such as species translocated by European colonizers during the past 500 years. We use genomic DNA from historical museum specimens and historical records to evaluate three hypotheses regarding the timing and origin of Northern Bobwhites (Colinus virginianus) in Cuba, whose status as an endemic or introduced population has long been debated. We discovered that bobwhites from southern Mexico arrived in Cuba between the 12th and 16th centuries, followed by the subsequent introduction of bobwhites from the southeastern USA to Cuba between the 18th and 20th centuries. These dates suggest the introduction of bobwhites to Cuba was human-mediated and concomitant with Spanish colonial shipping routes between Veracruz, Mexico and Havana, Cuba during this period. Our results identify endemic Cuban bobwhites as a genetically distinct population born of hybridization between divergent, introduced lineages.

Report of an unusual association of Oropouche Fever with Guillain-Barré syndrome in Cuba, 2024.

Oropouche virus is the aetiological agent of Oropouche fever. At present, this is currently considered one of the most important vector-borne diseases in Latin America. On 27 May 2024, the Ministry of Public Health of Cuba reported the first ever outbreak of Oropouche fever. In this report, we describe three human cases of Oropouche virus infection with symptoms and signs of neurological disease and clinical diagnosis of Guillain-Barré Syndrome. This study offers insights regarding that Oropouche virus is a causal agent of neurological disorders and it could be involved in the etiology of the Guillain-Barré Syndrome.

Assessing greenhouse gas emissions in Cuban agricultural soils: Implications for climate change and rice (Oryza sativa L.) production.

Assessing the impact of greenhouse gas (GHG) emissions on agricultural soils is crucial for ensuring food production sustainability in the global effort to combat climate change. The present study delves to comprehensively assess GHG emissions in Cuba's agricultural soil and analyze its implications for rice production and climate change because of its rich agriculture cultivation tradition and diverse agro-ecological zones from the period of 1990-2022. In this research, based on Autoregressive Distributed Lag (ARDL) approach the empirical findings depicts that in short run, a positive and significant impact of 1.60 percent % in Cuba's rice production. The higher amount of atmospheric carbon dioxide (CO2) levels improves photosynthesis, and stimulates the growth of rice plants, resulting in greater grain yields. On the other hand, rice production index raising GHG emissions from agriculture by 0.35 % in the short run. Furthermore, a significant and positive impact on rice production is found in relation to the farm machinery i.e., 3.1 %. Conversely, an adverse and significant impact of land quality was observed on rice production i.e., -5.5 %. The reliability of models was confirmed by CUSUM and CUSUM square plot. Diagnostic tests ensure the absence of serial correlation and heteroscedasticity in the models. Additionally, the forecasting results are obtained from the three machine learning models i.e. feed forward neural network (FFNN), support vector machines (SVM) and adaptive boosting technique (Adaboost). Through the % MAPE criterion, it is evident that FFNN has achieved high precision (91 %). Based on the empirical findings, the study proposed the adoption of sustainable agricultural practices and incentives should be given to the farmers so that future generations inherit a world that is sustainable, and healthy.

Which Stranger's Disease? Immigration, Immunization, and the Whitening of Cuba in the Age of Atlantic Revolutions.

In 1804, Cuban physician Tomás Romay tried and failed to create the first yellow fever vaccine. The article analyzes his experimental efforts, foregrounding the enslaved and enlisted subjects at the center of this early vaccine trial. Though a scientific failure, this brief experiment, the desires and logics embedded within it, and the measures deployed in its wake - in the form of European whitening campaigns - allow us to consider the political uses of immunity during the Age of Atlantic Revolutions. Historicizing these events within the wider geopolitics of the Caribbean, the article explicates the central role that yellow fever immunization played in Cuban authorities' attempts to shore up their political and economic sovereignty in the midst of anti-colonial and anti-slavery resistance. As such, it shows how yellow fever and its threat to social and economic order fits within a broader history of vaccination as a mechanism of colonial governance. Finally, by situating Cuban efforts to prevent yellow fever alongside the health concerns of enslaved people - concerns that arguably informed their resistance to slavery - the article also demonstrates how ideas about immunity and political belonging increasingly intersected through whiteness as an elite ideal in the era that Cuba first became a slave society.

'Y Compartimos. . .': the collective creation of performed fiction in practice.

This essay combines text and images in the style of a graphic novel to animate the lively and dynamic processes of a qualitative research approach that I call the collective creation of performed fiction. This is a form of projective storytelling in which participants draw on their own experiences to create and perform composite stories. Using fiction helps them avoid revealing sensitive details of their personal lives. The examples shared here are drawn from a long-term engagement with a group of youth in Old Havana, Cuba, where historic geopolitical tensions and emergent economic crises are interrupting the imagined futures of the young. This brief contribution documents key differences between three creative mediums used in this work (street theatre, film and animation), and addresses their varied capacities to mitigate the risks of self-disclosure.

First molecular characterization of Dirofilaria Immitis in Cuba.

BACKGROUND: Dirofilarioses are widespread diseases caused by mosquito-borne nematodes of the family Onchocercidae, genus Dirofilaria. The major etiologic agent of canine dirofilariosis in the American continent is the zoonotic parasite Dirofilaria immitis. Existing reports of filarioid nematodes in Cuba are based solely on morphological and immunological analysis which do not allow unambiguous identification and/or direct detection of causal agents. RESULTS: Here we present the molecular characterization of filarioid nematodes found in a dog in Cuba. Based on the molecular and phylogenetic analysis of the 5.8S-ITS2-28S region and cox1 gene fragments, the worms were unambiguously classified as D. immitis. Sequence analysis showed high identity of the gene fragments in this study with others previously obtained from D. immitis found in dogs, wolfs and jackals but also from mosquito vectors of D. immitis. CONCLUSIONS: Further studies are guarantee to better understand the epidemiological impact of canine dirofilariosis in Cuba as well as the competence of different species of culicid mosquitoes as vectors of Dirofilaria in the country.

Molecular study of a large cohort of 109 haemophilia patients from Cuba using a gene panel with next generation sequencing-based technology.

INTRODUCTION: In several countries, molecular diagnosis of haemophilia A (HA) and B (HB) is hampered by a lack of resources for DNA analysis. The advent of next-generation sequencing (NGS) has enabled gene analysis at a reasonable cost. AIM: Describe a collaboration between Cuban and Spanish researchers to identify candidate variants and investigate the molecular epidemiology of 106 Cuban haemophilia patients using NGS. PATIENTS/METHODS: The molecular analysis protocol included well-established LR-PCR procedures to detect F8 inversions, NGS with a 30-gene panel to sequence F8 and F9, and multiplex ligation-dependent probe amplification to identify large structural variants. RESULTS: One-hundred and thirty-one candidate variants were identified along F8, F9, and VWF; 72 were unique and 28 (39%) had not been previously recorded. Putative variants were identified in 105/106 patients. Molecular characterization enabled confirmation and reclassification of: 90 HA (85%), 15 HB (14%), and one type 2N VWD (1%). Null variants leading to non-production of FVIII or FIX were common in severe HA (64%), moderate HA (74%), and severe HB (60%), whereas missense variants were frequent in mild HA (57%) and moderate or mild HB (83%). Additional variants in VWF were identified in 16 patients. CONCLUSION: This is the first description of the molecular epidemiology of HA and HB in Cuba. Variants identified in index cases will be of value for local implementation of familial studies and prenatal diagnosis using the molecular approaches available in Cuba. The results of this protocolled genetic study improved the accuracy of the clinical diagnosis and will facilitate management of these patients.

'I did not get this disease on the street; it was brought home as a gift': Gender, violence and HIV vulnerability among Cuban women.

While gay, bisexual and other men who have sex with men are most affected by HIV in Cuba, infections among women have increased over time, but there has been little research to contextualise their vulnerability to HIV. The purpose of this study was to explore the role of gender and violence in shaping vulnerability to HIV among Cuban women. Qualitative in-depth interviews were conducted with women living with HIV at an outpatient HIV clinic in Havana. Narrative and thematic technique were used to systematically analyse the data. Participants described negotiating sexual relationships in a context where traditional gender norms merge with the paradox of increasing professional opportunities for women alongside growing economic precarity. Interconnected economic and emotional dependence along with violence influenced the acceptance of certain behaviours that heightened vulnerability to HIV, including inconsistent condom use and infidelity. Gender transformative approaches that recognise the complex interplay between gender norms, economic precarity and violence are needed to address women's vulnerability to HIV in the Cuban context. Such efforts can reinforce existing strategies to promote behaviourally focused prevention while creating an enabling environment for the integration and expansion of biomedical innovation in HIV prevention.

[The HEARTS Initiative in Cuba: experience of five years of implementationA Iniciativa HEARTS em Cuba: experiências após 5 anos de implementação]. / La Iniciativa HEARTS en Cuba: experiencias tras 5 años de implementación.

In order to describe the changes in the control of arterial hypertension from 2016 to 2021 and the relationship between the progress made and the maturity of implementation of the HEARTS Initiative at the first level of care in Cuba, a prospective implementation study was designed to promote the correct measurement of blood pressure with validated automatic sphygmomanometers, risk-based care, introduction of standardized antihypertensive treatment protocols, secondary prevention, and teamwork. Patient education, active case-finding, and community activities were also encouraged. Data were obtained from implementation logs and were analyzed with SPSS Statistics V21; outcome values and 95% confidence intervals were reported. Population indicators were evaluated: registration coverage, control between treatments, population control, and the HEARTS in the Americas Maturity Index. The number of participating centers increased from a single demonstration center in 2016 to 22 polyclinics in six provinces and seven municipalities in 2021. There was a significant increase in the absolute values for the total population served, number of hypertensive patients registered, controlled patients among those treated, and controlled hypertensive patients among all adults, although with annual variations in percentages of coverage, control between treatments, and population control. The greatest progress occurred in centers with high-performance health teams. Five years after implementation of the HEARTS Initiative in Cuba, the methodology is becoming institutionalized.

A fim de descrever as mudanças no controle da hipertensão arterial de 2016 a 2021 e a relação entre o progresso e a maturidade da implementação da Iniciativa HEARTS no primeiro nível de atenção em Cuba, foi elaborado um estudo prospectivo de implementação que promoveu a aferição correta da pressão arterial com esfigmomanômetros automáticos validados, cuidados baseados em risco, a introdução de protocolos padronizados de tratamento anti-hipertensivo, a prevenção secundária e o trabalho em equipe. A educação dos pacientes, a busca ativa de casos e as atividades comunitárias também foram incentivadas. Os dados foram obtidos a partir dos registros de implementação e foram analisados com o programa de estatística SPSS versão 21. São relatadas medidas de desfecho e seus intervalos de confiança de 95%. Foram avaliados os seguintes indicadores populacionais: cobertura de registro, controle entre os pacientes tratados e controle populacional, bem como o índice de maturidade dos processos da Iniciativa HEARTS nas Américas. Comparativamente, entre 2016 e 2021, o número de centros participantes aumentou de um só centro de demonstração para 22 policlínicas em 6 províncias e 7 municípios. Evidenciou-se um aumento significativo nos valores absolutos da população total atendida, do número de pessoas com hipertensão cadastradas, de pacientes controlados entre os tratados e de pessoas com hipertensão controlada entre todos os adultos, embora com variações anuais nos percentuais de cobertura, no controle entre os tratados e no controle populacional. Os maiores avanços ocorreram nos centros que têm equipes de saúde de alto desempenho. Cinco anos após a implementação da Iniciativa HEARTS em Cuba, avança-se rumo à institucionalização da metodologia.

Heavy metals in soils of Mayabeque, Cuba: multifaceted and hardly discernable contributions from pedogenic and anthropogenic sources.

Cuba is a country with considerable potential for economic growth, and special efforts are made to increase the agricultural output. As food production depends on the quality of soils, heavy metal concentrations were measured in 39 soils in the province of Mayabeque, Cuba, and interpreted in light of anthropogenic activities and pedogenic conditions (soil type and properties). With median concentrations of 1.8 Cd, 60.3 Cr, 48.1 Cu, 36.2 Ni, 16.7 Pb, 55.0 Zn, and 0.1 mg/kg Hg, soils of Mayabeque were mostly below Cuban quality reference values (QRV) representing benchmarks of quality standards but no official threshold values. Only Cd concentrations were in many cases above the QRV of 0.6 mg/kg and some Cu concentrations above the one of 83 mg/kg. While Cd, Cr, and Ni concentrations were rather pedogenically driven, Cu, Pb, Zn, and Hg contents were rather anthropogenically influenced. When evaluated statistically, Cd and Cr showed most times a significant influence of both sources. In contrast, Ni and Zn could not be significantly related with the origins investigated in this study. Hence, the allocation of heavy metal concentrations to pedogenic or anthropogenic contamination or pollution sources is tentative and needs further investigations. Nevertheless, the present data adds information on soil heavy metal concentrations in the Caribbean region, serves as reference before further industrial development, and sets the ground for adaptation of the QRV for Cd and possibly future national environmental standards.

Vaccinal chronicity: immunotherapy, primary care, and the temporal remaking of lung cancer's patienthood in Cuba.

The Cuban biotechnology industry is producing cancer immunotherapy, in particular, therapeutic vaccines that actively stimulate the immune system to stabilise the tumour. These products aim to transform metastatic malignancies into a chronic disease. Since 2010, this therapeutic concept has been integrated within a public health experiment, consisting of the large distribution of immunotherapies, including in primary healthcare centres, to enhance access and assess its effectiveness on a wider population of patients. Such experimental intervention, consisting of post-marketing clinical trials, has focused only on lung cancer, one of the most widespread and lethal cancers on the island. Combining interviews with ethnographic observations focusing on care performed by professionals, patients, and their relatives, this paper analyses the experience of lung cancer chronicity under this type of immunotherapy in Cuba. It shows how a certain form of continuity is made between prophylactic and therapeutic vaccination to shape a new temporality of cancer care, through the integration within primary care, constant access to biotechnology, and multiple care practices directed to strengthen the immunotherapy's efficacy. If vaccinal chronicity remains fragile due to its experimental dimension and the fact that long-term survivorship is still an exceptional phenomenon, lung cancer patienthood is deeply transformed through a shared effort of the people and the state to provide more stable, meaningful, and inclusive care.

Inequality of weight status in urban Cuba: 2001-2010.

BACKGROUND: Although understanding changes in the body weight distribution and trends in obesity inequality plays a key role in assessing the causes and persistence of obesity, limited research on this topic is available for Cuba. This study thus analyzed changes in body mass index (BMI) and waist circumference (WC) distributions and obesity inequality over a 9-year period among urban Cuban adults. METHODS: Kolmogorov-Smirnov tests were first applied to the data from the 2001 and 2010 National Survey on Risk Factors and Chronic Diseases to identify a rightward shift in both the BMI and WC distributions over the 2001-2010 period. A Shapley technique decomposed the increase in obesity prevalence into a mean-growth effect and a (re)distributional component. A univariate assessment of obesity inequality was then derived by calculating both the Gini and generalized entropy (GE) measures. Lastly, a GE-based decomposition partitioned overall obesity inequality into within-group and between-group values. RESULTS: Despite some relatively pronounced left-skewing, both the BMI and WC distributions exhibited a clear rightward shift to which the increases in general and central obesity can be mostly attributed. According to the Gini coefficients, both general and central obesity inequality increased over the 2001-2010 period, from 0.105 [95% confidence interval (CI) = 0.103-0.106] to 0.110 [95% CI = 0.107-0.112] and from 0.083 [95% CI = 0.082-0.084] to 0.085 [95% CI = 0.084-0.087], respectively. The GE-based decomposition further revealed that both types of inequality were accounted for primarily by within-group inequality (93.3%/89.6% and 87.5%/84.8% in 2001/2010 for general/central obesity, respectively). CONCLUSIONS: Obesity inequality in urban Cuba worsened over the 2001-2010 time period, with within-group inequality in overall obesity dominant over between-group inequality. In general, the results also imply that the rise in obesity inequality is immune to health care system characteristics.

Body-mass index, blood pressure, diabetes and cardiovascular mortality in Cuba: prospective study of 146,556 participants.

BACKGROUND: Cardiovascular disease accounts for about one-third of all premature deaths (ie, age < 70) in Cuba. Yet, the relevance of major risk factors, including systolic blood pressure (SBP), diabetes, and body-mass index (BMI), to cardiovascular mortality in this population remains unclear. METHODS: In 1996-2002, 146,556 adults were recruited from the general population in five areas of Cuba. Participants were interviewed, measured (height, weight and blood pressure) and followed up by electronic linkage to national death registries until Jan 1, 2017; in 2006-08, 24,345 participants were resurveyed. After excluding all with missing data, cardiovascular disease at recruitment, and those who died in the first 5 years, Cox regression (adjusted for age, sex, education, smoking, alcohol and, where appropriate, BMI) was used to relate cardiovascular mortality rate ratios (RRs) at ages 35-79 years to SBP, diabetes and BMI; RR were corrected for regression dilution to give associations with long-term average (ie, 'usual') levels of SBP and BMI. RESULTS: After exclusions, there were 125,939 participants (mean age 53 [SD12]; 55% women). Mean SBP was 124 mmHg (SD15), 5% had diabetes, and mean BMI was 24.2 kg/m2 (SD3.6); mean SBP and diabetes prevalence at recruitment were both strongly related to BMI. During follow-up, there were 4112 cardiovascular deaths (2032 ischaemic heart disease, 832 stroke, and 1248 other). Cardiovascular mortality was positively associated with SBP (>=120 mmHg), diabetes, and BMI (>=22.5 kg/m2): 20 mmHg higher usual SBP about doubled cardiovascular mortality (RR 2.02, 95%CI 1.88-2.18]), as did diabetes (2.15, 1.95-2.37), and 10 kg/m2 higher usual BMI (1.92, 1.64-2.25). RR were similar in men and in women. The association with BMI and cardiovascular mortality was almost completely attenuated following adjustment for the mediating effect of SBP. Elevated SBP (>=120 mmHg), diabetes and raised BMI (>=22.5 kg/m2) accounted for 27%, 14%, and 16% of cardiovascular deaths, respectively. CONCLUSIONS: This large prospective study provides direct evidence for the effects of these major risk factors on cardiovascular mortality in Cuba. Despite comparatively low levels of these risk factors by international standards, the strength of their association with cardiovascular death means they nevertheless exert a substantial impact on premature mortality in Cuba.

Seroprevalence of Toxoplasma gondii and associated risk factors in domestic pigs raised from Cuba.

A cross-sectional study was carried out to determine the seroprevalence of Toxoplasma gondii and associated risk factors in pigs in the largest pork-producing region in Cuba. Serum samples from 420 pigs, including 210 sows and 210 post-weaning pigs, were tested for antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay. Anti-T. gondii antibodies were detected in 56 animals (13.3%, 95% CI: 10.1-16.6). A generalized estimating equations model revealed that the risk factors associated with higher seropositivity in pigs were altitude (higher in farm's location < 250 m above sea level (masl) versus ≥ 250 masl) and age (higher in sows compared to post-weaning pigs). The results indicated that this protozoan parasite is widely distributed on pig farms in the study area, which is a public health concern since the consumption of raw or undercooked pork meat products containing tissue cysts is considered one of the main routes of T. gondii transmission worldwide. Control measures should be implemented to reduce the risk of exposure to T. gondii in pigs in Cuba.

Mortality rates immediately after severe hurricanes in Cuba have decreased over the past three decades.

OBJECTIVES: The objective of this study is to understand how Cuba responds to extreme weather events, which can help identify and disseminate good public health practice. STUDY DESIGN: The study design of this study is an observational study using routinely collected mortality data. METHODS: National daily mortality counts after severe hurricanes arrived on the Cuba landmass since 1990 were compared with baseline values. Incidence rate ratios of mortality during the hurricane and for the four weeks afterwards were calculated for four eligible hurricanes: Georges (1998), Dennis (2005), Ike (2008) and Irma (2017). RESULTS: Mortality rates decreased over time (P < 0.001 for interaction), and no excess mortality counts were observed after Hurricane Irma in 2017. CONCLUSIONS: Mortality rates for severe hurricanes that have made landfall in Cuba have decreased over three decades, despite the most recent hurricane (Irma) being one of the strongest observed in recent decades. This suggests that the Cuban public health preparations and responses to recent severe hurricanes are probably contributing to this mitigation in national mortality rates during these periods.

Equity and the Cuban National Health System's response to COVID-19.

Cuba's National Health System has managed to guarantee an effective and equitable response to COVID-19. Universal and free health coverage, based on primary care, follows the principle of equity and the greatest resources are allocated to areas of the lowest socioeconomic stratum (where higher risk is concentrated), followed by those of medium and high strata, in that order. This allowed for similar mortality rates in the three strata, and Cuban national mortality rate was one of the lowest in the Region of the Americas. Before the first case was identified in Cuba, a Plan for Coronavirus Prevention and Control was elaborated with multisectoral participation, and when the first case was confirmed the Temporary National Working Group to Fight COVID-19 was created as an advisory body of the government. The actions to face the pandemic began with preventive measures in the community, continued in the isolation centers and ended again in the community with actions of surveillance and follow up of recovered patients. Following the principle of territoriality, molecular diagnosis laboratories were created in the provinces that did not have one. Free medical care and treatment; the preparation of a single national intersectoral government plan; the use of particular strategies for research, diagnosis and case tracing; and the implementation of a universal protocol for disease prevention and treatment of confirmed cases made it possible to control the disease with a health equity perspective.

El Sistema Nacional de Salud de Cuba ha logrado garantizar una respuesta eficaz y con equidad en el enfrentamiento a la COVID-19. La cobertura de salud universal y gratuita, basada en la atención primaria, sigue el principio de equidad, por lo que los mayores recursos se asignan a los territorios del estrato socioeconómico más bajo, que concentra mayores riesgos de salud, seguidos de los de estratos medio y alto, en ese orden. Esto permitió tener tasas de letalidad similares en los tres estratos, y a nivel nacional la de Cuba es una de las tasas más bajas de la Región de las Américas. Antes de identificar el primer caso en Cuba, se elaboró el Plan para la Prevención y Control del Coronavirus, con participación multisectorial, y al confirmarse el primer caso se creó el Grupo Temporal de Trabajo para Enfrentar la COVID-19 como órgano asesor del Gobierno. Las acciones de enfrentamiento a la pandemia comienzan en la comunidad con medidas preventivas, continúan en los centros de aislamiento y terminan nuevamente en la comunidad, con acciones de vigilancia y acompañamiento a los enfermos recuperados. Siguiendo el principio de territorialidad, se crearon laboratorios de diagnóstico molecular en las provincias que no lo tenían. La atención médica y los tratamientos gratuitos; la preparación de un plan de gobierno intersectorial nacional único; la utilización de estrategias particulares para la pesquisa, diagnóstico y rastreo de casos; y la implementación de un protocolo universal para la prevención de la enfermedad y el tratamiento de los casos confirmados permitieron el control de la enfermedad con una perspectiva de equidad en salud.

O Sistema Nacional de Saúde de Cuba tem assegurado uma resposta eficaz e com equidade ao enfrentar a pandemia de COVID-19. A cobertura de saúde universal e gratuita baseada na atenção primária se pauta no princípio da equidade. Mais recursos são destinados às áreas de nível socioeconômico mais baixo que concentram risco de saúde maior e a seguir, nesta ordem, às áreas de nível socioeconômico médio e alto. Assim, a taxas de letalidade tem sido semelhante nos três níveis e a taxa nacional é uma das mais baixas da Região. Antes de o primeiro caso de COVID-19 ter sido detectado em Cuba, preparou-se o Plano para prevenção e controle do coronavírus com participação multissetorial. Quando o primeiro caso da doença foi confirmado, instituiu-se o Grupo de trabalho temporário para combater a COVID-19 como um órgão assessor do governo. As ações de combate à pandemia começam na comunidade com medidas preventivas, prosseguem nos centros de isolamento e retornam à comunidade com medidas de vigilância sanitária e o acompanhamento dos pacientes recuperados. E, seguindo o princípio de territorialidade, laboratórios de diagnóstico molecular foram instituídos nas províncias onde eles inexistiam. A atenção médica, o tratamento gratuito, a preparação de um plano de governo único intersetorial nacional, o emprego de estratégias próprias para pesquisa, diagnóstico e rastreio de casos e a implementação de um protocolo universal para prevenção da doença e tratamento dos casos confirmados possibilitaram controlar a doença de uma perspectiva de equidade em saúde.

Recommendations for coastal planning and beach management in Caribbean insular states during and after the COVID-19 pandemic.

The COVID-19 pandemic has implications for coastal planning and management. Rules for isolation and physical distancing, among other measures for human life protection, have led to the closure of most beaches around the world. The present critical situation has raised the following question: How can some recommendations be designed in sun, sea, and sand tourism-dependent-insular countries to face "the COVID-19 new normality?" We used the content analysis technique to analyze representative publications on a global level to ascertain information on best management practices. A survey of 58 experts provided additional information. We used inferential statistics for sample selection and produced a list of 43 practices and beach planning and management actions to face the COVID-19 pandemic. This led to 27 new recommendations designed for beach planning and management within insular contexts, some of which were tested in the Republic of Cuba. Recommendations aim to guarantee a culture of safety and improvement within the field of beach or coastal planning and management. These recommendations should prove useful for other insular countries, during the COVID-19 period, in the new normality that follows, and in other post-pandemic scenarios.

Immunogenicity of Intramuscular Fractional Dose of Inactivated Poliovirus Vaccine.

BACKGROUNDS: Intradermal (id) fractional inactivated poliovirus vaccine ([fIPV] one fifth of normal IPV dose) is safe and immunogenic; however, id administration is perceived as difficult. We compared fIPV immunogenicity administered id or intramuscularly (im). METHODS: This noninferiority trial was conducted among polio vaccine-naive Cuban infants who received 2 IPV doses at 4 and 8 months of age. Infants were randomized into 4 arms: (A) fIPV, 0.1 mL im; (B) fIPV, 0.2 mL im; (C) fIPV, 0.1mL id; and (D) IPV, 0.5 mL im. Blood collected before and after vaccinations was tested for poliovirus-neutralizing antibodies. RESULTS: A total of 196 of 214 (91.6%) enrolled children completed study. Seroconversion after 2 IPV doses in each arm were as follows: (A) 97.3% (90.6-99.7), 98.7% (92.7-99.9), and 90.5% (81.5-96.1) for serotypes 1, 2, and 3, respectively; (B) 97.2% (90.3-99.7), 100%, 95.8% (88.3-99.1) for serotypes 1, 2, and 3, respectively; (C) 89.3% (71.8-97.7), 92.9% (76.5-99.1), 82.1% (63.1-93.9) for serotypes 1, 2, and 3, respectively; and (D) 100%, 100%, 100% for serotypes 1, 2, and 3, respectively. Seroconversion with fIPV im was noninferior to fIPV id for all serotypes. CONCLUSIONS: We demonstrated noninferiority of fIPV im compared with id when administered at 4 and 8 months of age. Further investigations in an earlier infant schedule should be pursued to explore fIPV im as option for dose-sparing strategy in countries reluctant to use fIPV id due to programmatic difficulties of id administration.
