In the Lancet Respiratory Medicine, Nienke Scheltema and colleagues¹ shed some light on a simple question that has been stubbornly difficult to answer: does respiratory syncytial virus (RSV)-related lower respiratory tract infection in early infancy cause asthma later in childhood? The answer is important because it influences the value proposition for RSV prevention products under development. RSV disease in infancy is clearly a notable problem, with an estimated 118 220 RSV-related childhood deaths and more than 3·2 million RSV-related hospital admissions each year worldwide.

喘息或不喘息：预防RSV的问题

Nienke Scheltema及其同事¹在《柳叶刀呼吸医学》上阐明了一个一直难以回答的简单问题：婴儿早期与呼吸道合胞病毒（RSV）相关的下呼吸道感染是否会导致儿童期哮喘？答案很重要，因为它会影响正在开发的RSV预防产品的价值主张。婴儿中的RSV疾病显然是一个显着的问题，全世界估计每年有118220例与RSV相关的儿童死亡，每年有超过3·200万例与RSV相关的医院住院。
