Abstract Background Since their emergence in the Americas, chikungunya (CHIKV) and Zika (ZIKV) viruses co-circulate with dengue virus (DENV), hampering clinical diagnosis. We investigated epidemiological characteristics of arboviral infections during introduction spread CHIKV ZIKV through northeastern Brazil. Methods Surveillance for diseases among febrile patients was performed at an emergency health unit Salvador, Brazil, between September 2014 July 2016. interviewed to collect data on...
Vaccination is a major strategy to prevent the coronavirus disease 2019 (COVID-19). However, information about factors associated with men and women intention be vaccinated are scarce. To determine COVID-19 vaccine acceptance identify hesitancy according sex, we performed cross-sectional population-based random survey in Salvador, Brazil between Nov/2020-Jan/2021. Participants were interviewed obtain data on receive pay for vaccine, as well demographics, comorbidities, influenza vaccination...
Abstract Background Low-income urban communities in the tropics often lack sanitary infrastructure and are overcrowded, favoring Aedes aegypti proliferation arboviral transmission. However, as Ae. density is not spatially homogeneous, understanding role of specific environmental characteristics determining vector distribution critical for planning control interventions. The objectives this study were to identify main habitat types Aegypti , assess their spatial densities major hotspots...
After a chikungunya outbreak in Salvador, Brazil, we performed cross-sectional, community-based study of 1,776 inhabitants to determine virus (CHIKV) seroprevalence, identify factors associated with exposure, and estimate the symptomatic infection rate. From November 2016 through February 2017, collected sociodemographic clinical data by interview tested serum samples for CHIKV IgG. seroprevalence was 11.8% (95% CI 9.8%-13.7%), 15.3% seropositive persons reported an episode fever arthralgia....
ObjectivesTo investigate risk factors for persistent arthralgia in patients with chikungunya, and describe its impact on daily activities.MethodsFrom September 2014 to July 2016, a surveillance study enrolled acute febrile illness Salvador, Brazil, detected those chikungunya virus infection using IgM enzyme-linked immunosorbent assay or reverse transcriptase polymerase chain reaction. Telephone follow-ups were performed ascertain the progression of disease.ResultsOf 153 followed cases, 65...
The structural environment of urban slums, including physical, demographic, and socioeconomic attributes, renders inhabitants more vulnerable to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. Yet, little is known about the specific determinants that contribute high transmission within these communities. We therefore aimed investigate SARS-CoV-2 seroprevalence in an slum Brazil.
To evaluate whether oral fluids (OF) and urine can serve as alternative, non-invasive samples to diagnose chikungunya virus (CHIKV) infection via RT-qPCR, we employed the same RNA extraction RT-qPCR protocols on paired serum, OF collected from 51 patients with during acute phase of illness. Chikungunya were confirmed through in acute-phase sera (N = 19), IgM seroconversion between acute- convalescent-phase 12), or detection 20). The controls included non-arbovirus febrile illness 28)...
Background Adult T-cell leukemia/lymphoma (ATLL), a peripheral associated with the human lymphotropic virus type-1 (HTLV-1), has been classified following clinical forms defined by Shimoyama in 1991. A suggestion to modify Shimoyama’s classification was proposed 2007 differentiate within smoldering patients those who presented nodules or tumors skin without lung involvement, which named primary cutaneous tumoral (PCT) form of ATLL. In present study, according their clinicopathological...
The immunopathogenesis of chikungunya virus (CHIKV) infection and the role acute-phase immune response on joint pain persistence is not fully understood. We investigated profile serum chemokine cytokine in CHIKV-infected patients with acute disease, compared levels these biomarkers to those other febrile diseases (OAFD) healthy controls (HC), evaluated their as predictors chronic arthralgia development. Chemokines cytokines were measured by flow Cytometric Bead Array. Patients CHIKV further...
Background The first chikungunya virus (CHIKV) outbreaks during the modern scientific era were identified in Americas 2013, reaching high attack rates Caribbean countries. However, few cohort studies have been performed to characterize initial dynamics of CHIKV transmission New World. Methodology/Principal findings To describe shortly after its introduction Brazil, we semi-annual serosurveys a long-term community-based 652 participants aged ≥5 years Salvador, between Feb-Apr/2014 and...
This study investigated the self-rated general health, mental and work absenteeism among patients with laboratory-confirmed chikungunya.
The structural environment of urban slums, including physical, demographic and socioeconomic attributes, renders inhabitants more vulnerable to SARS-CoV-2 infection. Yet, little is known about the specific determinants that contribute high transmission within these communities.
A atenção primária à saúde é a porta de entrada do Sistema Único Saúde(SUS) e carrega o dever prestar preferencialmente primeiro atendimento ao usuário, orientando sobre prevenção doenças, promoção da saúde; assim como, também, sua função solucionar situações agravo saúde, direcionar os casos mais complexos aos demais níveis atenção. Ao longo dos anos muitas iniciativas foram desenvolvidas pelo SUS para aproximar população primária, sendo Estratégia Saúde Família(ESF) uma das principais....
Introdução: Doença renal crônica (DRC) é um termo geral usado para designar alterações que afetam tanto a estrutura, quanto função renal. Essas anormalidades podem apresentar múltiplas causas e prognóstico variado; Objetivo do estudo: Investigar associação entre problemas renais outras comorbidades em pacientes cadastrados na USF Alto das Pombas, no município de Salvador-Bahia; Material métodos: Trata-se estudo epidemiológico, observacional, corte transversal, analítico, visa descrever...
