Respiratory syncytial virus (RSV) and influenza are prevalent seasonal community viruses. Although not completely understood, SARS-CoV-2 may have the same means of transmission. Preventive social measures aimed at preventing spread could impact transmission other respiratory viruses as well. The aim this study is to report detection RSV during period distancing due COVID-19 pandemic in a heavily affected community.Prospective with pediatric adult populations seeking care for COVID-19-like...
COVID-19 manifests as a milder disease in children than adults, but the underlying mechanisms are not fully characterized. Here we assess difference cellular or humoral immune responses of pediatric and adult patients to see if these factors contribute severity dichotomy. Children's non-specific profile is dominated by naive lymphocytes HLA-DR
Changes in the epidemiology of respiratory infections during restrictions imposed as a response to coronavirus disease 2019 (COVID-19) pandemic have been reported elsewhere. The present study's aim was describe prevalence large array pathogens symptomatic children and adolescents Southern Brazil.Hospitalized outpatients aged 2 months 18 years with signs symptoms acute COVID-19 were prospectively enrolled study from May November 2020 two hospitals metropolitan area Brazilian city. All...
The viral dynamics and the role of children in spread severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are not completely understood. Our aim was to evaluate reverse transcription polymerase chain reaction (RT-PCR) cycle threshold (Ct) values among with confirmed SARS-CoV-2 compared that adult subjects.Patients (from months ≤18 years age adults) signs symptoms infection for less than 7 days were prospectively enrolled study from May November 2020. All participants performed...
Abstract Background The viral dynamics and the role of children in spread SARS-CoV-2 are not completely understood. Our aim was to evaluate RT-PCR Ct values among with confirmed compared that adult subjects. Methods Patients (aged from 2 months ≤18 years, adults) signs symptoms acute infection for less than 7 days, were prospectively enrolled study May November 2020. All participants performed assay detection; ORF1ab, N, S gene-targets, average all three probes used as surrogates load....
This is the third year of SARS-CoV-2 pandemic, and yet most children remain unvaccinated. COVID-19 in manifests as mostly mild or asymptomatic, however high viral titers strong cellular humoral responses are observed upon acute infection. It still unclear how long these persist, if they can protect from re-infection and/or disease severity. Here, we analyzed immune memory a cohort adults with COVID-19. Important differences between evident kinetics profile responses. Children develop early...
to evaluate the accuracy of an antibody point-of-care lateral flow immunoassay (LFI - Wondfo Biotech Co., Guangzhou, China) in a pediatric population.children and adolescents (2 months 18 years) with signs symptoms suggestive acute SARS-CoV-2 infection were prospectively investigated nasopharyngeal RT-PCR LFI at emergency room. was performed baseline, same time or scheduled for those less than 7 days clinical picture. Overall accuracy, sensitivity specificity assessed, as well according...
Streptococcus pneumoniae colonization patterns are influenced by host and environmental factors, which may be related to Invasive Pneumococcal Disease (IPD). Interestingly, COVID-19 pandemic witnessed a decline in the incidence of IPDs. Investigations with diligent data collection on prevalence nasopharyngeal associated serotypes during this unique period can yield novel insights. The aim current study was assess S. carriage among children adults who have sought care at emergency departments...
To investigate the prevalence and factors associated with no intention to exclusively breastfeed for first 6 months of life in a sample women 24 h postpartum during hospital stay.
Point-of-care serological tests for SARS-CoV-2 have been used COVID-19 diagnosis. However, their accuracy over time regarding the onset of symptoms is not fully understood. We aimed to assess a point-of-care lateral flow immunoassay (LFI). Subjects, aged 18 years, presenting clinical suggestive acute infection were tested once by both nasopharyngeal and oropharyngeal RT-PCR LFI. The LFI was assessed in periodic intervals three days relation symptoms. optimal cut-off point defined as number...
Abstract Epidemiological evidence that COVID-19 manifests as a milder disease in children compared to adults has been reported by numerous studies, but the mechanisms underlying this phenomenon have not characterized. It is still unclear how frequently get infected, and/or generate immune responses SARS-CoV-2. We performed profiling of pediatric and adult patients Brazil, producing over 38 thousand data points, asking if cellular or humoral could help explain children. In study, presented...

Abstract Background/Objectives The aim of this study was to evaluate the association between obesity and hospitalization in mild COVID-19 adult outpatients Brazil. Subjects/Methods Adults with signs symptoms suggestive acute SARS-CoV-2 infection who sought two hospitals (one public one private) emergency department (ED) were prospectively enrolled. Patients confirmed at inclusion followed by phone calls day (D) D7, D14 D28. Multivariable logistic regression models employed explore other...
Introduction: Pneumococcal pneumonia is a leading cause of severe disease, to approximately 2.2 million hospital admissions in 2019 Brazil.Since 2010, the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine was introduced Brazil, as part National Immunization Program (NIP) with universal access, approximated coverage 91.4% 2019.Although studies from many countries are available, there still need understand effect introduction on incidence hospitalizations...
O Streptococcus pneumoniae é uma das principais bactérias associadas a coinfecções virais. Informações quanto à colonização pneumocócica e são limitadas, incluindo possível associação com SARS-CoV-2. objetivo deste estudo foi descrever as frequências de S. identificação outros agentes respiratórios patogênicos comuns, durante o primeiro ano da pandemia COVID-19. Estudo observacional prospectivo em participantes idade >10 anos, sintomas respiratórios, entre maio novembro/2020. Foi realizado...
Streptococcus pneumoniae é um importante colonizador nasofaríngeo, e potencial causador de infecções graves invasivas em crianças. Desde 2010, a vacina pneumocócica conjugada 10 (PVC-10) está disponível pelo Programa Nacional Imunizações. O objetivo deste estudo foi descrever colonização S. identificar outros patógenos durante o primeiro ano da pandemia COVID-19. Foram recrutados observacional prospectivo, crianças (≤10 anos) dois hospitais do Sul Brasil entre maio novembro 2020. A presença...
Apesar do predomínio SARS-CoV-2 como etiologia das infecções virais em adultos durante o ano de 2020, outros agentes infecciosos podem fazer parte diagnóstico diferencial.
