自2019年12月新型冠狀病毒肺見相炎（coronavirus disease 劇歌2019，COVID-19）暴發(fā)以來，世界各國(guó)相繼科時出現了大量新型冠狀病毒（severe acu件音te respiratory syndrome corona器熱virus 2，SARS-CoV-2）小新感染病例。SARS-CoV-2對(duì)全球公共海購衛生安全造成(chéng)了巨大威脅。疫情發(的開fā)生以來，相關科研人員從SARS-CoV-2的病原學(x去業ué)特點、流行病學(xué)特征、病原學(xué)檢測、科明治療與愈後(hòu)症狀等方面(miàn)進(jìn)行了研究。本文對(d鄉數uì)上述幾個方面(miàn)的研究成(chéng)果進(的廠jìn)行了彙總。研究發(fā)現：SARS-Co制有V-2以其遺傳多樣(yàng)性和重組頻繁的特點不斷産生變異體，以山動更大的傳播力感染人群；目前已知的2種(zhǒn通輛g)傳染途徑爲跨物種(zhǒng)傳播和空金人際傳播，其中飛沫傳播和接觸傳播是人際傳播制還的主要傳播途徑；感染人群遍布各個煙裡年齡段，其中患有慢性疾病的老年人更容易發(fā紅哥)展成(chéng)危重病人；臨床檢測時(shí)聯合核酸件線和抗原抗體檢測，將(jiāng)有助于提高SARS-CoV-2些愛感染的檢出率并排除其他冠狀病毒感染的可能(néng)性；目前尚未有治療C森農OVID-19的特效藥物，臨床上廣泛使用廣譜抗病毒藥物或中藥來治療各知林種(zhǒng)症狀；全球各國(guó)正在加緊研發湖訊(fā)SARS-CoV-2疫苗話市，部分疫苗已進(jìn)入臨床試驗階段。本文有助于全面(miàn)了解SA坐來RS-CoV-2的研究狀況，也爲熱分其後(hòu)續研究及防治提供了參考。
