New perspectives on respiratory syncytial virus surveillance at the national le...
Teirlinck, Anne C.; Johannesen, Caroline K.; Broberg, Eeva K.; Penttinen, Pasi; Campbell, Harry; Nair, Harish; Reeves, Rachel M.; Bøås, HåkonLearning from the COVID-19 pandemic and considering the effects of this pandemic, we provide recommendations that can guide towards sustainable RSV surveillance with the potential to be integrated into the broader perspective of respiratory surveillance.
The epidemiological signature of influenza B virus and its B/Victoria and B/Yam...
Caini, Saverio; Kusznierz, Gabriela; Garate, Verònica Vera; Wangchuk, Sonam; Thapa, Binay; de Paula Júnior, Francisco JoséWe describe the epidemiological characteristics, pattern of circulation, and geographical distribution of influenza B viruses and its lineages using data from the Global Influenza B Study. We included over 1.8 million influenza cases occurred in thirty-one countries during 2000-2018. We calculated the proportion of cases caused by influenza B and its lineages; determined the timing of influenza A and B epidemic...
Distribution of influenza virus types by age using case-based global surveillan...
Caini, Saverio; Spreeuwenberg, Peter; Kusznierz, Gabriela F.; Rudi, Juan Manuel; Owen, Rhonda; Pennington, Kate; Wangchuk, Sonam; Gyeltshen, SonamBackground: Influenza disease burden varies by age and this has important public health implications. We compared the proportional distribution of different influenza virus types within age strata using surveillance data from twenty-nine countries during 1999-2014 (N=358,796 influenza cases). Methods: For each virus, we calculated a Relative Illness Ratio (defined as the ratio of the percentage of cases in an a...
Antiviral drug profile of seasonal influenza viruses circulating in Portugal fr...
Correia, Vanessa; Andrade, Helena Rebelo de; Santos, Luís A.; Lackenby, Angie; Zambon, MariaA research project on antiviral drug resistance of influenza viruses circulating in Portugal has been carried out since 2007. Here, the first results obtained regarding the evaluation of susceptibility to amantadine and oseltamivir are presented. Information about antiviral prescription and exposure was available through the National Influenza Surveillance Programme. Amantadine susceptibility was evaluated by p...
