A. A.流感A相比，流感B被标记为“ B”团队，据信与某些流感菌株（例如H3N2）相比，据信是一种温和的病毒。比H1N1这样的流感A菌株更有效[4]。实际上，多项研究表明，流感B病毒在引起严重疾病和死亡率方面增加了效力。流感B是每四到五年最突出的流感菌株。 Furthermore, influenza B infections carried higher risks of hospitalisations compared to influenza A infections in HIV patients [5]. Similarly, influenza B has been described to have significantly higher mortality rates compared to influenza A strains. For example, during the flu season in 2010–2011, influenza B was responsible for 38% of deaths in the paediatric population. National Respiratory and Enteric Virus Surveillance System collaborating laboratories indicated that only 26% of circulating strains of flu were influenza B viruses during this period [6]. Similarly, a Canadian study from 2004 to 2013 found significantly higher mortality rates due to influenza B compared to influenza A in children younger than 16 years of age [7]. These data strongly refute the claims that influenza B is the milder version of the flu. In this issue of the European Respiratory Journal, the study by Bui et al. [8] sheds light on influenza B interactions within the human respiratory tract and lung to demonstrate its pathogenicity and its potential to spread and cause severe lung infections.Influenza B virus can be as virulent as influenza A http://bit.ly/2SnBZ72 ER -
