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.

Sáez-López, Emma; Cristóvão, Paula; Costa, Inês; Pechirra, Pedro; Conde, Patrícia; Guiomar, Raquel; Peres, Maria João; Viseu, Regina; Lopes, PauloIntroduction: Respiratory 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. Objective: The objective of the present study was to describe RSV epidemiolog...
Influenza virus type/subtype and different infection profiles by age group duri...
Guiomar, Raquel; Pechirra, Pedro; Cristóvão, Paula; Costa, Inês; Conde, Patrícia; Côrte-Real, Rita; Branquinho, Paula; Garcia, David; Conde, SílviaBackground: Influenza has a major impact in hospitalization during each influenza season. We analysed the influenza type/subtype distribution by age group and medical care wards (ambulatory, hospital, intensive care unit). Material and Methods: During 2017/2018 season, 14 hospitals from Portugal mainland and Atlantic Island (Azores and Madeira) reported to the National Influenza Centre 13747 cases of respirator...
Influenza seroprotection correlates with predominant circulating viruses during...
Guiomar, Raquel; Cristóvão, Paula; Conde, Patrícia; Costa, Inês; Pechirra, Pedro; Rodrigues, Ana Paula; Pereira da Silva, Susana; Nunes, BaltazarBACKGROUND: Population immune profile for influenza is highly affected by circulating influenza viruses, thus changing the risk of infection for influenza. This study aims to assess influenza immunity in the Portuguese population by age groups, during 2014 and 2015 and establish a relationship between seroprotection and circulating influenza viruses in 2014/15 and 2015/16 seasons. METHODS: Two cross-sectional s...
Influenza severe cases in hospitals, between 2014 and 2016 in Portugal
Guiomar, Raquel; Pechirra, Pedro; Cristóvão, Paula; Costa, Inês; Conde, Patrícia; Corte-Real, Rita; Branquinho, Paula; Silvestre, Maria JoséBackground: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) case...
