To describe the clinical manifestations and severity of children adolescents affected by COVID-19 treated at Sabará Hospital Infantil.This is a cross-sectional, retrospective, observational study. All cases confirmed RT-qPCR patients seen hospital (emergency room, first-aid ICU) were analyzed. The was classified according to Chinese Consensus.Among 115 included, predominance boys (57%) verified, median age two years. A total 22 hospitalized, 12 in ICU. Of total, 26% had comorbidities with...
Background The respiratory syncytial virus (RSV) is recognized as an important cause of tract infections. Immunocompromised patients, healthcare workers (HCWs) and children contacts are at increased risk acquiring the infection. However, impact asymptomatic infection in transmission has not been well studied. Objectives: this study evaluated frequency viral load (VL) RSV nasal swab samples individuals with different factors for a university hospital Sao Paulo, Brazil. Methods We included 196...
In a single day, six of 150 (4%) asymptomatic visitors were diagnosed with COVID-19 at hospital universal masking policy. Two inpatients (contacts) subsequently developed symptoms. More rigorous protective measures during visitation periods may need to be included in infection control practices reduce nosocomial transmissions.
Neospora caninum, a cause of abortion and stillbirth in cattle, was studied by histology, immunohistochemistry, nested-PCR, using primers from the Nc5 region genomic DNA (PCR PLUS) ITS1 ribosomal JB).A total 105 fetal samples sent to Centro de Pesquisa e Desenvolvimento Sanidade Animal do Instituto Biológico January 2006 May 2008 were examined for evidence N. caninum.Histological examination revealed 71.4% with non-suppurative inflammation heart, lung, liver, kidney, placenta,...
Influenza A coinfections with other respiratory viruses were investigated in 25.8% (41/159) of the samples from patients hospitalized 2009 at our University Hospital. Out 41 influenza cases, nine cases (21.9%) coinfected viruses, a similar frequency among children and adults (p = 0.47), seasonal more prevalent than H1N1 virus. Adenovirus was most frequently detected (4/9) cases. Coinfection not associated higher morbidity or mortality 0.75).
During the first pandemic wave of influenza A H1N1 2009 virus, morbidity was particularly high in Brazil. Hospitalizations resulting from severe respiratory disease due to suspected influenza-like illness created an opportunity identify other viruses causing lower infections. The purpose this study assess viral etiologies among samples collected during hospitalized patients with cases a Brazilian Sentinel Hospital. Patients and methods: Viral were investigated 98 children 61 adults fever,...
INTRODUCTION: During the first pandemic wave of influenza A H1N1 2009 virus, morbidity was particularly high in Brazil. Hospitalizations resulting from severe respiratory disease due to suspected influenza-like illness created an opportunity identify other viruses causing lower infections. OBJECTIVE: The purpose this study assess viral etiologies among samples collected during hospitalized patients with cases a Brazilian Sentinel Hospital. PATIENTS AND METHODS: Viral were investigated 98...
INTRODUCTION: Human adenoviruses (HAdV) play an important role in the etiology of severe acute lower respiratory infection, especially immunocompromised individuals. The aim present study was detect HAdV through different methods: direct fluorescence assay (DFA) and nested-polymerase chain reaction (PCR-nested) from patients with infection (ARI) up to 7 days symptoms onset. METHODS: Samples (n=643) were collected risk groups during 2001 2010: 139 adults attended Emergency Room Patients...
The role of rhinovirus asymptomatic infections in the transmission among close contacts subjects is unknown. We tested health care workers, a pair one child and family member immunocompromised patients (n =191). HRV were detected on 22.9% symptomatic 3.6% cases suggesting lower contacts.
To produce an epidemiological map of neosporosis in Brazil and identify the types transmission this disease, present study evaluated occurrence Neospora caninum Nelore cattle (Bos indicus) Presidente Prudent, west region Sao Paulo state; its vertical transmission; early stage which fetuses are infected. achieve this, serum samples from 518 slaughtered pregnant heifers their were tested by ELISA technique fetal brain tissues subjected to PCR. One hundred three (19.88%) had antibodies N....
Adenoviruses play an important role in the etiology of severe acute lower respiratory infection, especially young children. The aim present study was to evaluate Human Adenovirus (HAdV) detection by different methods (Direct Fluorescence Assay - DFA and Nested Polymerase Chain Reaction nested PCR), among samples collected from groups pediatric patients.Collection made children with congenital heart disease (CHD 123 nasal aspirates years 2005, 2007 2008) community (CC 165 2008). Children were...

Abstract First in Manaus the Brazilian Northern region, Variant of Concern P.1 traveled 3800 kilometers southeast to endanger Sao Paulo contributing collapse health system. Here, we show evidence how fast VOC has spread most populated city South America.
INTRODUCTION: Influenza A H1N1 2009 is associated with a high morbidity rate among children around the world, including Brazil. This survey was conducted on samples of symptomatic (< 12 years) to investigate influenza virus as etiological agent respiratory infections in day care school health facility during first and second pandemic wave (2009-2010) São Paulo, METHODS: were determined by real-time PCR 34% (47/137) median age 5 years (8 months - years), from June October 16% (14/85) those...
The aim of this study was to determine if Toxoplasma gondii present in aborted bovine fetuses Brazil. Histopathology 105 cases with suspected infectious abortion, analyzed during the period from 2006 2008 at Centro de Pesquisa e Desenvolvimento Sanidade Animal Instituto Biológico, São Paulo, showed 75 indications abortion due apicomplexan protozoa. These were submitted PCR for verification laboratory diagnosis. Fetal DNA extracted central nervous system, heart, liver, muscle, and/or placenta...

Out 41 influenza cases, nine cases (21.9%) coinfected viruses, a similar frequency among children and adults (p = 0.47), seasonal more prevalent than H1N1 virus.

Em 2010, 96 pacientes com suspeita de infecção por influenza A (H1N1) foram hospitalizados no Hospital São Paulo, na cidade Paulo (SP). Desses, 4 (4,2%) diagnosticados - 3 e 1 sazonal 2 (2,1%) B. maioria dos casos suspeitos (63,5%) metade positivos ocorreram em crianças. segunda onda foi mais fraca Paulo. vacinação pode ter contribuído para a redução das internações devido essa 2010.
This study assessed the presence of influenza virus among young children and coverage vaccination from 2010 to 2012 in São Paulo, Brazil. Our results demonstrated a lower rate detection predominance B. A decrease through surveillance periods was observed.
Parainfluenza virus infections (PIV) were evaluated in patients with mild and severe through real time PCR. One thousand sixty-seven samples collected from subjects as follows: 233 adult renal transplanted outpatients, 129 children congenital heart disease, 381 hematopoietic stem cell 324 hospitalized suspected of influenza A (H1N1) pdm09 infection. PIV was detected 74 (6.9%) samples. VPI-3 the most frequent (60.8%) a higher risk observed for older adults (p = 0.018) those who transplanted....
