研究：新冠病毒或借助大气污染物颗粒传播
<p>意大利科学家的最新研究显示，新冠病毒能够附着在大气污染物颗粒上，这或许可以使病毒传播得更远，导致更多人感染。</p><p> <span word="Lines">Lines</span> <span word="of">of</span> <span word="cars">cars</span> <span word="are">are</span> <span word="pictured">pictured</span> <span word="on">on</span> <span word="Guomao">Guomao</span> <span word="Bridge">Bridge</span> <span word="in">in</span> <span word="Beijing">Beijing</span>, <span word="Dec">Dec</span> 8, 2019.
