This overview of severe acute respiratory syndrome coronavirus 2 circulation over 1.5 years in Guinea demonstrates that virus clades and variants of interest and concern were progressively introduced, mostly by travellers through Conakry, before spreading through the country. Sequencing is key to following virus evolution and establishing efficient control strategies.
本研究概述了 1.5 年来塞内加尔境内严重急性呼吸综合征冠状病毒 2 的传播情况，表明病毒的进化枝和感兴趣的变异株和关切变异株主要是通过旅行者经科纳克里传入，随后在国内传播。病毒进化的关键是测序和建立有效的控制策略。
