/></p><p><span>基于目前的流行病学调查和研究结果，潜伏期为1-14天，多为3-7天；发病前1-2天和发病初期的传染性相对较强；传染源主要是新型冠状病毒感染的患者和无症状感染者；主要传播途径为经呼吸道飞沫和密切接触传播，接触病毒污染的物品也可造成感染，在相对封闭的环境中长时间暴露于高浓度气溶胶情况下存在经气溶胶传播的可能。</span></p><p><br /></p><p><span>由于在粪便、尿液中可分离到新型冠状病毒，应当注意其对环境污染造成接触传播或气溶胶传播。人群普遍易感。感染后或接种新型冠状病毒疫苗后 可获得一定的免疫力，但持续时间尚不明确。</span></p><p><br /></p><section data-mpa-template="t" mpa-from-tpl="t" data-mid=""><section
