Abstract: Resumo Imunizações de rotina durante pandemias podem ser prejudicadas. Este estudo estimou a cobertura vacinal para influenza em idosos durante a COVID-19 através do EPICOVID-19, inquérito populacional realizado em 133 cidades sentinelas dos 26 estados brasileiros e Distrito Federal. Selecionou-se 25 setores censitários por cidade, amostragem proporcional ao tamanho, dez domicílios por setor e uma pessoa por domicílio, aleatoriamente. O quantitativo de 8.265 idosos (≥ 60 anos) (more) foram entrevistados e responderam se haviam sido vacinados contra gripe em 2020. A cobertura foi 82,3% (IC95% 80,1; 84,2), sem diferenças por sexo, idade ou região. Maiores coberturas ocorreram nos mais ricos (84,7% versus 80,1% nos mais pobres) e nos mais escolarizados (87,3% versus 83,2% nos menos escolarizados). Menor cobertura nos indígenas (56,9% versus coberturas superiores a 80% nos demais grupos étnicos). Houve associação positiva com número de comorbidades entre homens, mas não entre mulheres. A maioria vacinou-se na rede pública (97,5%), sendo a rede privada mais utilizada na região Sul, pelos mais escolarizados e mais ricos. Conclui-se que a cobertura vacinal ficou sete pontos percentuais abaixo da meta governamental (90%), e que desigualdades devem ser revertidas em futuras campanhas.

Abstract Routine immunization during pandemics can be harmed. This study estimated the influenza vaccination coverage in older adults during the COVID-19 through the EPICOVID-19, a population-based study conducted in 133 cities from the 26 Brazilian states and Federal District. We selected 25 census tracts per city, with probability proportional to the tract's size, ten households by census tract, and one random individual interviewed. A total of 8,265 older adults (≥60 years old) were interviewed and asked whether they had been vaccinated against flu in 2020. Vaccination coverage was 82.3% (95% CI: 80.1-84.2) with no difference by gender, age, and region; higher vaccination coverage was observed among the wealthiest (84.7% versus 80.1% in the poorest) and among the more educated (87.3% versus 83.2% less educated); lower coverage among indigenous (56.9% versus > 80% among other ethnic groups). A positive association was identified with the number of comorbidities among men but not among women. Most of the population was vaccinated (97.5%) in the public health system. The private network was chosen mainly in the South by the wealthiest and more educated. Vaccination coverage was seven percentage points lower than the government target (90%), and inequalities should be reversed in future campaigns.

Abstract: RESUMEN Introducción: La influenza tiene elevado impacto en la mortalidad humana y en Cuba la categoría influenza y neumonía ocupa el cuarto lugar entre sus causales generales. En los países templados, con marcada estacionalidad, esto se capta con modelos estadísticos, tarea que se dificulta en el trópico y pendiente en Cuba por la ausencia de igual definición estacional. Objetivo: Estimar el impacto histórico de la influenza tipo A y B y los subtipos A(H3N2) y A(H1N1) sobre la (more) mortalidad mediante el ajuste de un modelo de regresión a las condiciones estacionales específicas de Cuba. Métodos: Se ejecutó un estudio longitudinal y retrospectivo. En un primer paso se ajustaron dos modelos de Poisson con la mortalidad influenza y neumonía total y las personas ≥ 65 años de edad como variables respuestas en los cinco meses de mayor positividad en influenza, desde la temporada 1987-1988 hasta la 2004-2005 y los positivos en tipo A y en tipo B como explicatorias. En otro par de modelos se estimó el impacto del A(H3N2) y el A(H1N1), considerando como respuesta los fallecidos atribuidos previamente al tipo A. Resultados: Se atribuyeron a la influenza 7803 fallecidos entre todas las edades y 6152 entre las personas ≥ 65 años de edad, con un 56,3 % asociados al A(H3N2), el 17,6 % al A(H1N1) y el 26,1 % al tipo B. Conclusiones. Se logró estimar el impacto de la influenza sobre la mortalidad mediante el ajuste para Cuba de un modelo estadístico que permitió demostrar la asociación de la circulación de estos virus con la mortalidad en el país, lo que ratifica la necesidad de reforzar la vigilancia, el control y la vacunación contra esta infección viral. Se demuestra la posibilidad de ajustar estos modelos de regresión a otros virus respiratorios y a la actual pandemia por la COVID-19, en las condiciones estacionales de Cuba.

ABSTRACT Introduction: Influenza has a high impact on human mortality and in Cuba influenza and pneumonia rank fourth among its general causes. In temperate climate countries, with marked seasonality, this is captured by statistical models, a task that is difficult in the tropics and pending in Cuba due to the absence of the same seasonal definition. Objective: Estimate the historical impact of influenza type A and B and subtypes A(H3N2) and A(H1N1) on mortality, by adjusting a regression model to the specific seasonal conditions of Cuba. Methods: A longitudinal and retrospective study was performed. In a first step, two Poisson models were adjusted with influenza and total pneumonia mortality and people ≥ 65 years old as response variables in the five months with the highest positivity to influenza in the period 1987-1988 to 2004-2005, and the positive ones to type A and type B as explanatory variables. In another pair of models was estimated the impact of A(H3N2) and A(H1N1), considering as a response the deaths previously attributed to type A. Results: 7 803 deaths among all ages and 6 152 among 65-year-olds were attributed to influenza, with 56.3% associated to A(H3N2), 17.6% to A(H1N1) and 26.1% to type B. Conclusions: It was possible to estimate the impact of influenza on mortality by adjusting for Cuba a statistical model that demonstrated the association of the circulation of these viruses with the mortality in the country, which confirms the need to strengthen surveillance, control and vaccination against this viral infection. The possibility of adjusting in the seasonal conditions of Cuba these regression models to other respiratory viruses and the current pandemic by COVID-19 is demonstrated.

Abstract: RESUMO Apresentação de um caso de infecção por Influenza B e doença de Kawasaki em adolescente ocorrido durante a pandemia da COVID-19. Adolescente asmática evoluiu com febre e síndrome gripal por 7 dias e deu entrada com quadro de insuficiência respiratória aguda, necessitando de intubação orotraqueal. Evoluiu também com instabilidade hemodinâmica respondedora ao uso de droga vasoativa. Foram introduzidas antibioticoterapia e medidas de suporte. Apresentou melhora hemodinâmic (more) a e respiratória progressiva, porém mantinha febre e alteração de provas inflamatórias. Durante internação, evoluiu com conjuntivite não purulenta bilateral, descamação de mão e pés, língua em framboesa e linfonodomegalia cervical, recebendo diagnóstico de doença de Kawasaki. Recebeu gamaglobulina e, por conta de quadro clínico refratário, foi administrado também corticoide, evoluindo afebril 24 horas após. Não apresentou alterações coronarianas. O único agente isolado foi Influenza B, mesmo realizando painel viral e investigação para COVID-19 com reação em cadeia da polimerase e sorologia. Durante internação, apresentou tromboembolismo pulmonar, e, em investigação de coagulopatias, foi diagnosticada com mutação em heterozigose de fator V de Leiden. Há uma potencial associação entre doença de Kawasaki e infecção por Influenza B ou outros vírus, como o coronavírus e, por isso, esses diagnósticos devem ser investigados nos pacientes pediátricos, incluindo adolescentes, com quadros febris prolongados.

ABSTRACT We report a case of Influenza B infection and Kawasaki disease in an adolescent, diagnosed during the COVID-19 pandemic. An asthmatic female adolescent presented with fever and flu-like symptoms for 7 days and was admitted with acute respiratory failure requiring mechanical ventilation. She progressed with hemodynamic instability responsive to vasoactive drugs. Antibiotic therapy and support measures were introduced, showing progressive hemodynamics and respiratory improvement, however with persistent fever and increased inflammatory markers. During the hospitalization, she developed bilateral non-purulent conjunctivitis, hand and feet desquamation, strawberry tongue, and cervical adenopathy, and was diagnosed with Kawasaki disease. She was prescribed intravenous immunoglobulin and, due to the refractory clinical conditions, corticosteroid therapy was added; 24 hours later, the patient was afebrile. No coronary changes were found. A full viral panel including COVID-19 C-reactive protein and serology could only isolate the Influenza B virus. During the hospitalization, she was diagnosed with pulmonary thromboembolism; coagulopathies were investigated, and she was diagnosed with heterozygous factor V Leiden mutation. There is a potential association between Kawasaki disease and infection with Influenza B or with other viruses such as coronavirus. Therefore, this association should be considered in pediatric patients, adolescents included, with prolonged febrile conditions.

Abstract: Resumen Introducción: En el contexto de la pandemia de COVID-19 existe inquietud en cuanto al impacto de la temporada de influenza. Objetivo: Analizar el impacto del antecedente de inmunización contra influenza en pacientes con infección por SARS-CoV-2. Métodos: Se incluyeron pacientes mayores de 18 años con COVID-19, registrados entre marzo y agosto de 2020. Los datos fueron analizados mediante las pruebas exacta de Fisher y t de Student. Para evaluar el impacto en la mortalidad se (more) utilizó un modelo de regresión logística; la relación entre el porcentaje de pacientes a quienes se aplicó la vacuna contra la influenza y la mortalidad fue determinada con el coeficiente de correlación de Pearson. Resultados: Se incluyeron 16 879 participantes; 17 % tuvo antecedente de vacunación contra influenza. La mortalidad fue menor en el grupo con historia de vacunación (3.5 % versus 7 %, p < 0.0001). El porcentaje de vacunación presentó una relación inversa con el porcentaje de mortalidad (r de Pearson 0.922, p = 0.026). Conclusiones: La inmunización contra la influenza fue un factor protector independiente de mortalidad en pacientes con COVID-19. Aunque son necesarios más estudios para determinar la relación causal, será razonable incrementar la inmunización contra influenza en la población general.

Abstract Introduction: In the context of the COVID-19 pandemic, there is concern regarding the impact of the influenza season. Objective: To analyze the impact of influenza immunization history on patients with SARS-CoV-2 infection. Methods: Patients older than 18 years with COVID-19, registered between March and August 2020, were included. Data were analyzed using Fisher's exact test and Student's t-test. To evaluate the impact on mortality, a logistic regression model was used; the relationship between the percentage of patients who received the influenza vaccine and mortality was determined with Pearson's correlation coefficient. Results: 16,879 participants were included; 17 % had a history of influenza vaccination. Mortality was lower in the group with a history of vaccination (3.5 % vs. 7 %, p < 0.0001). The vaccination rate had an inverse relationship with the mortality rate (Pearson's r: -0.922, p = 0.026). Conclusions: Previous influenza immunization was an independent protective factor for mortality in patients with COVID-19. Although further studies are needed to determine a causal relationship, it would be reasonable to increase influenza immunization in the general population.

Abstract: Apesar de incipientes, estudos têm contribuído com orientações a respeito de procedimentos para o afastamento de trabalhadores expostos direta ou indiretamente ao SARS-CoV-2, com sintomas de Síndrome Gripal ou de Síndrome Respiratória Aguda Grave ou que testaram positivo para Covid-19. Ainda há lacunas sobre as condutas necessárias para avaliação do retorno ao trabalho que extrapolem a abordagem clínica. Este estudo visa orientar a tomada de decisão, o planejamento e a adoção (more) de medidas eficazes de proteção à saúde dos trabalhadores que retornam ao ambiente de trabalho após adoecimento por Covid-19. Realizou-se revisão da produção técnico-científica sobre Covid-19, afastamento e retorno ao trabalho e sistematização em documento orientador sobre o tema. Propõe-se elementos essenciais para a avaliação de retorno ao trabalho após adoecimento por Covid-19 mediante desenvolvimento de ações sincrônicas nas dimensões indivíduo, ambiente de trabalho e atores sociais. Tais ações consideram desde a real situação de saúde do(a) trabalhador(a) até as condições do ambiente de trabalho para o qual o(a) trabalhador(a) irá retornar, mediadas pelos atores envolvidos. A decisão sobre o tempo de afastamento do trabalho pautada apenas em critérios clínicos tende a ser restritiva e insuficiente frente à complexidade do processo de adoecimento por Covid-19, devendo-se incorporar aspectos psicossociais e adequações nos locais de trabalho.

Although incipient, studies have contributed with guidance regarding procedures for the removal of workers exposed directly or indirectly to SARS-CoV-2; with symptoms of Flu Syndrome or Severe Acute Respiratory Syndrome; and/or tested positive for Covid-19. There is still a gap on the necessary conducts for returning to work that go beyond the clinical approach. This study aims at guiding decision-making, planning and adoption of effective measures to protect the health of workers that return to the work environment after falling ill by Covid-19. A review of the technical-scientific production on Covid-19, removal and return to work was conducted, and systematized in a guiding document on the subject. Essential elements are proposed for the assessment of return to work after illness by Covid-19 by the development of synchronous actions in the individual, work environment and social actor dimensions. Such actions consider the real health situation of the worker and the conditions of the work environment to which the worker will return, mediated by the actors involved. The decision on the time away from work based only on clinical criteria tends to be restrictive and insufficient considering the complexity of the illness process by Covid-19, and psychosocial aspects and adaptations in the workplace should be incorporated.

Aunque incipientes, los estudios han contribuido con la orientación sobre los procedimientos del alejamiento de trabajadores expuestos directa o indirectamente al SARS-CoV-2; con síntomas de síndrome de gripe o síndrome respiratorio agudo severo, o que dieron positivo para Covid-19. Aún existen lagunas en las conductas necesarias para la reinserción al trabajo que van más allá del abordaje clínico. Este estudio tiene como objetivo orientar la toma de decisiones, la planificación y la adopción de medidas efectivas de prevención a la salud de los trabajadores que regresan al entorno laboral después de enfermarse por Covid-19. Se realizó una revisión de la producción técnico-científica sobre Covid-19, alejamiento y vuelta al trabajo y una sistematización en un documento guía sobre el tema. Se proponen elementos esenciales para evaluar la reinserción al trabajo después de la enfermedad por Covid-19 mediante el desarrollo de acciones sincrónicas en las dimensiones individual, de ambiente laboral y de actores sociales. Tales acciones contemplan desde la situación real de salud del trabajador hasta las condiciones del entorno laboral al que retornará el trabajador, mediadas por los actores involucrados. La decisión sobre el tiempo de baja laboral basada únicamente en criterios clínicos tiende a ser restrictiva e insuficiente ante la complejidad del proceso de enfermedad por Covid-19, debiendo incorporarse aspectos psicosociales y adaptaciones en el ámbito laboral.

Abstract: Resumo Objetivo Avaliar a proporção de pessoas idosas não vacinadas e os motivos que interferem na imunização contra influenza em localidades rurais ribeirinhas, discutindo as potenciais implicações na vacinação contra a infecção por SARS-CoV-2. Método Inquérito epidemiológico de base domiciliar realizado em 38 localidades rurais ribeirinhas de Manaus (AM), Brasil, assistidas por uma Unidade Básica de Saúde Fluvial. Os participantes responderam a um questionário (more) que investigou condições de vida, saúde e acesso aos serviços de saúde. Para este estudo foram avaliados os desfechos relacionados à imunização contra a Influenza nos últimos 12 meses e o principal motivo alegado para a não vacinação. Foi realizada análise descritiva dos dados, seguida por análise de regressão logística para identificar fatores associados à não vacinação. Resultados Das 102 pessoas idosas incluídas no estudo, 28 (27,5%) referiram não vacinação contra a Influenza no ano anterior. Os principais motivos foram a falta de informação sobre a vacinação (60,7%) e barreiras de acesso aos serviços de saúde (28,6%). Foi identificada maior chance de não vacinação entre aqueles que não consultaram o médico no último ano (RC=4,18; IC95%=1,57-11,11) e com maior renda domiciliar (RC=1,08; IC95%=1,02-1,14). Conclusão Verificou-se elevada proporção de pessoas idosas autorreferindo não imunização contra Influenza. Os motivos identificados para a não vacinação podem também representar barreiras à vacinação desse grupo populacional contra a covid-19. Dessa forma, faz-se necessário adequar o planejamento da vacinação em contextos rurais ribeirinhos, desenvolvendo estratégias mais contextualizadas para garantia de cobertura a essa população com maior vulnerabilidade aos efeitos de doenças respiratórias.

Abstract Objective To evaluate the proportion of unvaccinated older adults and the reasons that interfere with immunization against Influenza in rural riverside locations, discussing the potential implications on vaccination against SARS-CoV-2 infection. Method Household-based survey conducted in 38 rural riverside locations in Manaus, Amazonas, Brazil, covered by a primary care Fluvial Health Unit. Participants answered a questionnaire that investigated living conditions, health status and access to health services. In this study, the outcomes related to immunization against Influenza in the last 12 months and the main reported reason for non-vaccination were evaluated. Descriptive data analysis was performed, followed by logistic regression to identify factors associated with non-vaccination. Results Of the 102 older adults included in the study, 28 (27.5%) reported not vaccinating against Influenza in the previous year. The main reasons were lack of information about vaccination (60.7%) and barriers to accessing health services (28.6%). An increased chance of non-vaccination was identified among those who did not see a doctor in the last year (OR=4.18; 95%CI=1.57-11.11) and those with higher household income (OR=1.08; 95%CI= 1.02-1.14). Conclusion A high proportion of older adults reporting no immunization against Influenza was identified. The reasons for non-vaccination may also represent barriers to the vaccination of this population group against COVID-19. Thus, it is necessary to improve the vaccination planning in rural riverside contexts, developing more contextualized strategies to assure coverage for this population, more vulnerable to the effects of respiratory diseases.

Abstract: Influenza viruses exacerbate chronic obstructive pulmonary disease (COPD) with considerable morbidity and mortality. Zanamivir and oseltamivir are effective in treating influenza. However, their efficacy in relieving influenza symptoms in COPD patients remains unknown, with the lack of controlled trials in this subject. Therefore, we conducted this randomized controlled trial to investigate the clinical efficacy of both interventions in this population. Patients were allocated to two groups (more)
