Resumo: El brote de la enfermedad por coronavirus 2019 (COVID-19), causado por el virus del síndrome respiratorio agudo severo tipo-2 (SARS-CoV-2), fue decla-rado como una pandemia en marzo de 2020. Las tasas de letalidad se estiman entre 1% y 3%, afectando principalmente a los adultos mayores y a aquellos con comorbi-lidades, como hipertensión, diabetes, enfermedad cardiovascular y cáncer. El perio-do de incubación promedio es de 5 días, pero puede ser hasta de 14 días. Muchos paci (mais)

Resumo: Influenza activity in the United States was low during October 2018, and, although it increased slowly during November, activity remains low across most of the country.* During the week ending December 1, 2018, the percentage of outpatient visits for influenza-like illness (ILI) was equal to the national baseline (Figure) and was at or slightly above the region-specific baseline in four of the 10 U.S. Department of Health and Human Services regions (Regions 4 and 7-9).

Single-Step Detection of the Influenza Virus Hemagglutinin Using Bacterially-Produced Quenchbodies.

Autor(es): Jeong, Hee-Jin; Dong, Jinhua; Ueda, Hiroshi
Fonte: Sensors (Basel);19(1)2018 Dec 23.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 30583603
Resumo: We have successfully generated a Quenchbody that enables the detection of the influenza virus hemagglutinin (HA), in a simple and convenient manner. By two-site labeling of the bacterially-produced anti-HA Fab with ATTO520, its fluorescence intensity was increased to 4.4-fold, in the presence of a nanomolar concentration of H1N1 HA. Our results indicate the potential use of this Quenchbody, as a sensor for the simple in situ detection of influenza A virus.

An equine influenza virus outbreak was identified in vaccinated and unvaccinated horses in a veterinary school hospital in São Paulo, SP, Brazil, in September 2015. The twelve equine influenza viruses isolated belonged to Florida Clade 1. The hemagglutinin and neuraminidase amino acid sequences were compared with the recent isolates from North and South America and the World Organisation for Animal Hea (mais)

Resumo: RESUMO No período sazonal compreendido entre 2014 e 2015, a maior parte das infecções por influenza decorreu do vírus influenza A H3N2. Mais de dois terços dos vírus influenza A H3N2 circulante eram antigênica e geneticamente diferentes (drift) do componente A H3N2 da vacina da influenza sazonal 2014 - 2015 para os hemisférios norte e sul. O objetivo deste trabalho foi relatar um caso de infecção por influenza A sazonal não H1N1 ocorrido em junho de 2015 em um paciente adulto com (mais)

Resumo: BACKGROUND: Mobile phones are commonly used by healthcare workers (HCW) in the working environment, as they allow instant communication and endless resource utilisation. Studies suggest that mobile phones have been implicated as reservoirs of bacterial pathogens, with the potential to cause nosocomial infection. This study aimed to investigate the presence of Respiratory Syncytial Virus, Adenovirus and Influenza Virus on HCWs mobile phones and to identify risk factors implied by HCWs practi (mais)

Resumo: BACKGROUND: There is increasing recognition of the role of B cell dysfunction in HIV pathogenesis, but little is known about how these perturbations may influence responses to vaccinations. METHODS: Healthy controls (n=16) and antiretroviral therapy (ART)-treated aviremic HIV-infected subjects (n=26) receiving standard-of-care annual influenza vaccinations were enrolled in the present study. Total bacterial 16S rDNA levels were assessed by quantitative polymerase chain reactions in plasma. (mais)

A systematic review of reported reassortant viral lineages of influenza A.

Autor(es): Pinsent, Amy; Fraser, Christophe; Ferguson, Neil M; Riley, Steven
Fonte: BMC Infect Dis;16: 3, 2016 Jan 05.
MEDLINE - Literatura Internacional em Ciências da Saúde PMID: 26732146
Resumo: BACKGROUND: Most previous evolutionary studies of influenza A have focussed on genetic drift, or reassortment of specific gene segments, hosts or subtypes. We conducted a systematic literature review to identify reported claimed reassortant influenza A lineages with genomic data available in GenBank, to obtain 646 unique first-report isolates out of a possible 20,781 open-access genomes. RESULTS: After adjusting for correlations, only: swine as host, China, Europe, Japan and years between 1 (mais)

Resumo: The probability of detecting influenza A virus (IAV) in oral fluid (OF) specimens was calculated for each of 13 assays based on real-time reverse-transcription polymerase chain reaction (rRT-PCR) and 7 assays based on virus isolation (VI). The OF specimens were inoculated with H1N1 or H3N2 IAV and serially diluted 10-fold (10(-1) to 10(-8)). Eight participating laboratories received 180 randomized OF samples (10 replicates × 8 dilutions × 2 IAV subtypes plus 20 IAV-negative samples) and p (mais)
