Pechirra, Pedro; Cristóvão, Paula; Costa, Inês; Conde, Patrícia; Silva, Susana; Torres, Ana Rita; Machado, Ausenda; Rodrigues, Ana PaulaRelatório anual do Programa Nacional de Vigilância da Gripe (PNVG). A presente publicação descreve a caraterização clínica e laboratorial da atividade gripal na época 2019/2020. O PNVG assegura a vigilância epidemiológica da gripe em Portugal, integrando as componentes de vigilância clínica e laboratorial. A componente clínica possibilita o cálculo de taxas de incidência permitindo descrever a intensidade e evo...
ESCALA DE MATURAÇÃO MACROSCÓPICA E MICROSCÓPICA DO VERDINHO (Micromesistius pou...
Gonçalves, Patrícia; Costa, Ana M.; Ferreira, Ana Luísa; Resende, Adelaide; Carmo Nunes Silva,; Abreu, Paula; Pechirra, PedroBlue whiting (Micromesistius poutassou) is a mesopelagic teleost, of the gadidae family and widely distributed along the Atlantic North and Mediterranean. On the Portuguese coast, the main spawning season for this species occurs between January and March. At IPMA, the biological sampling of blue whiting is carried out regularly, in samples from discards collected onboard commercial vessels, fishing landings (Pe...
Influenza vaccine effectiveness estimates using the test-negative design with d...
Gómez, Verónica; Kislaya, Irina; Machado, Ausenda; Pechirra, Pedro; Costa, Inês; Cristóvão, Paula; Conde, Patrícia; Guiomar, Raquel; Nunes, BaltazarBackground: The test-negative design (TND) has been used to monitor influenza vaccine effectiveness (IVE). Negative controls are those that tested negative for any influenza virus - however, there are issues related to the selection of the negative controls; As it is hypothesized a potential bias introduced by virus interference in TND, some authors suggest to use other respiratory virus as control group. Hence...
Predominance of influenza virus A(H3N2) 3C.2a1b and A(H1N1)pdm09 6B.1A5A geneti...
Melidou, Angeliki; Hungnes, Olav; Pereyaslov, Dmitriy; Adlhoch, Cornelia; Segaloff, Hannah; Robesyn, Emmanuel; Penttinen, Pasi; Olsen, Sonja J.Background: The 2018/2019 influenza season in the WHO European Region was dominated by influenza A (H1N1)pdm09 and (H3N2) viruses, with very few influenza B viruses detected. Methods: Countries in the European Region reported virus characterization data to The European Surveillance System for weeks 40/2018 to 20/2019. These virus antigenic and genetic characterization and haemagglutinin (HA) sequence data were ...

Rose, Angela; Kissling, Esther; Emborg, Hanne-Dorthe; Larrauri, Amparo; McMenamin, Jim; Pozo, Francisco; Trebbien, Ramona; Mazagatos, ClaraBackground: Influenza A(H1N1)pdm09, A(H3N2) and B viruses were co-circulating in Europe between September 2019 and January 2020. Aim: To provide interim 2019/20 influenza vaccine effectiveness (VE) estimates from six European studies, covering 10 countries and both primary care and hospital settings. Methods: All studies used the test-negative design, although there were some differences in other study characte...

Gómez, Verónica; Kislaya, Irina; Pechirra, Pedro; Conde, Patrícia; Costa, Inês; Nunes, Baltazar; Guiomar, Raquel; Machado, AusendaThe results to be presented are related to the 2018/19 EuroEVA season (the Portuguese component of the multicentre I-MOVE study) and aimed to estimate the end of season influenza vaccine effectiveness i) in general population; ii) in <65 and ≥65 years age groups; iii) in the target group for vaccination and iv) by influenza A subtype.
Epidemiology and genetic variability of respiratory syncytial virus in Portugal...
Sáez-López, Emma; Cristóvão, Paula; Costa, Inês; Pechirra, Pedro; Conde, Patrícia; Guiomar, Raquel; Peres, Maria João; Viseu, Regina; Lopes, PauloRespiratory syncytial virus (RSV) is associated with substantial morbidity and mortality since it is a predominant viral agent causing respiratory tract infections in infants, young children and the elderly. Considering the availability of the RSV vaccines in the coming years, molecular understanding in RSV is necessary.
Mortalidade atribuível ao vírus sincicial respiratório em Portugal entre 2014 e...
Rodrigues, Ana Paula; Silva, Susana; Torres, Ana Rita; Guiomar, Raquel; Pechirra, Pedro; Cristóvão, Paula; Nunes, BaltazarO vírus sincicial respiratório (RSV) tem sido reconhecido como um importante agente patogénico, especialmente em crianças menores de cinco anos e idosos. Nos adultos a infeção por RSV é geralmente pouco grave e autolimitada, mas em termos populacionais tem sido reconhecido o impacto na morbilidade e mortalidade. Com este trabalho pretendemos estimar a mortalidade por todas as causas atribuível à infeção por RSV...
Hospital-based test negative case control study to measure seasonal influenza v...
Gómez, Verónica; Kislaya, Irina; Pechirra, Pedro; Conde, Patrícia; Costa, Inês; Cristóvão, Paula; Nunes, Baltazar; Guiomar, Raquel; Machado, AusendaObjectives: The aim of the EVA Hospital study was to measure IVE against influenza laboratory confirmed SARI hospitalized in the older adult population at national level and contribute to the European estimate. In specific, it was intended to estimate 2018-19 seasonal influenza VE against SARI laboratoryconfirmed influenza requiring hospitalization, when possible: by age group (65-79 years, 80+ years) and; by p...
